Carpal tunnel syndrome is a compressive neuropathy affecting the median nerve. Compressive neuropathy is characterized by a progressive injury to a nerve caused by pressure—either constant or intermittent—typically from surrounding soft tissues like muscles, ligaments and tendons. The median nerve relays nerve impulses from the hand and wrist along the arm, and it is commonly compressed at the carpal tunnel, which is formed at the wrist by the transverse carpal ligament. When this happens, the outer covering of the nerve, called the myelin sheath, is injured due to a lack of blood flow, reducing the nerves’ ability to conduct signals. Small nerve fibers, such as those that conduct light touch and temperature, are affected by compression of the median nerve first. If carpal tunnel syndrome progresses, the larger fibers, like those that conduct impulses to muscles, can be affected as well. Unfortunately, this condition is progressive: if left untreated, carpal tunnel syndrome will result in increased damage to the nerve until it no longer functions.

The most common symptoms of carpal tunnel syndrome are numbness and tingling in digits innervated by the median nerve—the thumb, index, long and half of the ring finger. This numbness and tingling may be especially present at night time, and can very often wake you up. Some patients also complain of weakness, loss of dexterity, and repeated instances of dropping objects. Pain can be present, but it is not always there; some people who suffer from carpal tunnel never experience pain outside of the discomfort of numbness and tingling.

Carpal tunnel syndrome is the most common hand-related problem we treat. Despite it’s mythical status, the age-old idea that carpal tunnel syndrome is caused by typing has been disproven. Carpal tunnel syndrome is more accurately described as a disorder of aging. As we get older, our tissues become less compliant and therefore are less able to tolerate transient swelling (tendonitis) which can be aggravated by wrist position while sleeping.  Sleeping with your wrists bent can cause irritation and swelling of the nerve, which will in turn increase the daytime symptoms of carpal tunnel syndrome. Furthermore, people with comorbidities like diabetes, thyroid disorders, rheumatoid arthritis and obesity are prone to carpal tunnel syndrome. Carpal tunnel syndrome can also present as a swelling-related complication of pregnancy, although it is relatively rare.

There are a number of treatment options available to you, depending on how your carpal tunnel syndrome is graded. Mild carpal tunnel syndrome is often treated with nighttime splinting and reassessment at a later date to ensure there has been no progression of symptoms. Moderate and severe carpal tunnel syndrome often requires surgical intervention, known as carpal tunnel release (CTR). Unfortunately, there are many studies showing there is no significant benefit from steroid injections, therapy, ultrasound, or any other non-operative treatment for patients with moderate to severe carpal tunnel syndrome. We recently published an article in the Journal of Hand Surgery showing that those with moderate carpal tunnel syndrome have superior outcomes at any given time tested after surgery when compared to patients with severe carpal tunnel syndrome. This study also showed that if a patient has moderate carpal tunnel syndrome and has surgery the outcome is predictable, while those with severe carpal tunnel syndrome have a more unpredictable outcome.

Carpal Tunnel Syndrome

Medial epicondylitis “Golfer’s Elbow” is a tendinosis (degeneration, not inflammation) of the tendon insertion at the elbow of the muscles that flex the wrist and pronate the forearm (turn the hand palm down). It is a very common condition, but not anywhere near as common at lateral epicondylitis or tennis elbow.

The most common symptoms of medial epicondylitis are a pain at the inside of the elbow when gripping, lifting or swinging a racket or stick for sport. This is what gives the condition its moniker. In addition, almost all patients will have pain at the bump on the inside of the elbow (medial epicondyle of the humerus).

The age range is similar to those with lateral epicondylitis at 35-65 years of age.  While tennis elbow is usually not caused by tennis, golfers’ elbow can in fact be caused by golf, especially if one’s swing needs “some work.” Other causes of the condition can be overuse with any type of lifting exercise, improper weight lifting (straight bar biceps curls), or sudden pulling with the wrist flexed. Patients often experience pain inside the elbow with use or activity.

It is important to remember that the condition is a result of tendon degeneration, not inflammation. For this reason, traditional anti-inflammatory medications do not work. These include NSAIDs and steroid injections. There are no definitive studies telling us what treatment works best.  In addition, most all treatments work the same as doing nothing. Therefore, we generally set patients up with a trial of physical therapy. Eccentric exercises and aggressive soft tissue mobilization set up by a trained therapist with a home program will usually decrease symptoms and allow the patient to return to sport. However, there is no need to wait for healing to return to sports or work either. We believe that if a patient will do the exercises before their activity, they will be able to perform better and without pain. The program should be incorporated as part of the warm-up. In rare cases, patients may need surgical treatment. The surgery is simple–but will require post-operative immobilization for 10-14 days followed by a supervised therapy regimen.

Golfer’s Elbow

The scaphoid is the most commonly injured of the carpal bones. We have eight total carpal bones set in two rows. The scaphoid ‘bridges’ both rows of bones, which is why it is commonly fractured in a fall.

First, the scaphoid bone can suffer a non-displaced fracture that does not show up on routine x-rays. The bone itself is in the shape of a twisted peanut, making visualization difficult.  This may lull patients into a false sense of security of thinking the bone isn’t broken just because initial x-rays were read as ‘normal’. However, a non-displaced fracture can easily transition into a displaced fracture if not detected and immobilized. Second, the blood supply to the scaphoid comes from the distal or hand side–this means the blood supply comes through the bone, not into the bone. Therefore, the blood supply is disrupted if the bone is broken, which can cause the bone to heal properly and, in some cases, even die.

Most scaphoid fractures occur in males, with an average age of 25. Up to 61% of scaphoid fractures occur during a sporting event. Furthermore, because of the nature of those typically injured, they can often present weeks or months following the injury with an unhealed fracture.

Non-displaced scaphoid fractures can be treated in a cast. A non-displaced fracture will have less than 1mm of a ‘step-off’ or gap at the fracture site and is usually found in younger children.  Any complete fracture will need operative fixation. In minimally displaced fractures, this is done with a screw, but sometimes bone grafting is needed because the fracture is comminuted or in multiple pieces.

Scaphoid Fractures

Arthritis describes joint destruction and is broken down into three types: osteoarthritis, inflammatory arthritis and post-traumatic arthritis. The most common form is Osteoarthritis (OA), which is when the smooth layer of cartilage breaks down and does not heal. Inflammatory arthritis, which is less common than OA, is an autoimmune attack on the cells that line the joints and tendons (synovial cells). Post-Traumatic arthritis is also called “wear and tear arthritis” as it occurs when persistent joint irregularities and joints remain unstable or loose and cause a loss of their cartilage. 

Surprisingly, the most common symptom of arthritis in the fingers is a painless swelling at the distal interphalangeal joint or the end knuckle of the finger. It is very common to get osteoarthritis in this joint. It usually doesn’t hurt, but it can limit motion. Arthritis will first cause swelling and loss of motion, but pain can arise as the joint spaces become narrowed or irregular.  Sometimes arthritis can give rise to mucinous cysts in this joint, a common side effect.

Osteoarthritis is by far the most common type of arthritis in the hands and fingers. For some reason, it is more common in women than in men. Some people can get osteoarthritis at a very young age (20-30) whiles others may live into their 90s with no arthritis.

Activity modification, anti-inflammatory medication, and splinting can help individuals who have minor arthritis. However, there is nothing to prevent or slow the progression of osteoarthritis or post-traumatic arthritis. If an individual has inflammatory arthritis, treatment by a rheumatologist is warranted, as some patients can benefit from disease-modifying medications. Surgical treatment is reserved for those with continued pain. Surgical treatment for finger arthritis will not increase motion or function; it will only decrease pain. Surgical intervention for finger arthritis is mostly dependent on the location of the arthritic joint.

Finger Arthritis

The flexor tendons are the long tendons that run from the mid-forearm to the fingertip; each finger has two flexor tendons, and the thumb has one. The muscles that connect to these tendons originate in the forearm even though their action is in the hand. Their actions are complex, and their injuries to them are devastating.

The most common flexor tendon injury mechanism is a laceration from a sharp object like a knife, saw, or glass. You can also rupture a tendon when grabbing something or trying to tackle an opponent, hence the common name for an avulsion injury: “jersey finger.”  Frequently, an avulsion injury is thought to be a “sprain” as the finger hurts and swells but can still partially flex.

Researchers have published thousands of papers about the operative repair of flexor tendons, and surgeons have trialed numerous methods and implants. Today, the preferred method for repairing lacerations is multiple sutures crossing the gap (the area where the tendon is lacerated). Unfortunately, the treatment of choice for avulsions is less clear; if possible, surgeons fix the tendon to the bone with added sutures. Physical therapy with a Certified Hand Therapist (CHT) is mandatory for anyone recovering from a flexor tendon injury. Often, patients will be sent to see a hand therapist before surgery.

Flexor Tendon Injuries

The triceps is a tripinnate muscle, meaning it is made up of three parts–the long, medial, and lateral heads. It extends the elbow and allows the arm to be held in place in space. The triceps originates on the humerus and runs down the upper arm where it attaches to the olecranon process of the ulna. The triceps tendon can get tendonitis or suffer a frank rupture. Both can look similar. Furthermore, a rupture is often not ‘complete’ and can confuse the diagnosis.

Inflammation of the triceps as it inserts on the olecranon tip, which causes pain on the tip of the elbow and weakness. This inflammation is likely not an inflammatory state, but rather a degenerative one (like tennis elbow and golfer’s elbow).

Most often, males that participate in vigorous activity suffer from triceps tendon injuries. Common injury mechanisms include weight lifting, football, or heavy manual labor.  It is typically caused by an eccentric load on an outstretched arm.

Loss of extension strength of the elbow is helpful for diagnosis but is not always present. Often, the triceps is incompletely ruptured, and some extension is possible. An MRI or ultrasound will make a definitive diagnosis. In those individuals with less than a 50% rupture in children and the non-athlete, we can treat a rupture using physical therapy with excellent results. However, those with significant ruptures or athletes are generally treated with surgical repair.

Triceps Tendons Injuries

The distal radius is the end (distal) portion of the forearm bone (radius). It connects to the carpal bones at the wrist and runs parallel to the ulna, which is the other bone of the forearm. The radius transmits up to 80% of the forces across the wrist to the forearm. In traumatic injuries, the distal radius breaks close to or at its joint with the carpal bones of the wrist. These fractures most often occur as the result of a fall on an outstretched wrist. It is the most common type of fracture in the arm.

Many distal radius fractures are dorsally displaced due to the nature of the injury (a fall on an outstretched hand). They can be extra-articular—meaning the joint is not involved—or intra-articular, meaning the fractures spread into the wrist joint.  Intra-articular fractures have a worse prognosis as they involve fractures of multiple bones, not just the radius. After a fall, there will often be swelling, pain, and limited motion in the affected wrist. In extreme cases, there can be an obvious, or visible, deformity in the wrist.

Distal radius fractures are very common in two subsets of patients: children and the middle-aged. They are the most common arm fracture in kids, as they spend a great deal of time at play, which can lead to falls. These fractures are typically non-displaced, or ‘greenstick,’ fractures. At the other end of the age spectrum, middle-aged patients, particularly those with moderate osteoporosis, commonly experience these fractures as the result of falls brought on by instability in gait and balance. Of course, anyone who participates in activities capable of generating enough force to break bones—think contact sports, roller or ice skating, cycling, etc.—can experience a distal radius fracture.

Non-displaced distal radius fractures can be treated in a cast until swelling and pain have subsided. For an adult, a non-displaced distal radius fracture will heal over the course of six to ten weeks. Over the course of healing, frequent x-rays are taken to ensure there has been no significant displacement of the bone as it is healing. A fracture brace can also be used in place of a splint. Displaced distal radius fractures in children are most often externally reduced and casted. Sometimes the reduction needs to be held in place with an external pin. In either case, the reduction is done under sedation to ensure the patient does not feel pain during the procedure. Displaced distal radius fractures in adults are usually treated with open reduction and internal fixation. This is most often accomplished with a plate placed on the palm side of the forearm. With stable plate fixation, patients can often go into a removable brace two to four weeks after surgery.

Distal Radius Fracture

In general, arthritis describes joint destruction. Arthritis can be broken down into three broad types. Osteoarthritis (OA), which is the most common form, is when the smooth layer of cartilage breaks down and does not heal. Much less common than OA, inflammatory arthritis is an autoimmune attack on the cells that line the joints and tendons (synovial cells). Post-Traumatic arthritis is also called “wear and tear arthritis” as it occurs when persistent joint irregularities and joints remain unstable or loose and cause a loss of their cartilage.

The first symptom is typically a loss of motion, especially in extension. Patients report that they can’t “get their elbow out.” Pain at the end of flexion can also occur. Swelling, instability, and mechanical symptoms can also occur as the condition progresses. Numbness in the pinky and weakness in the hand can occur from compression of the ulnar nerve at the elbow.

Comprehensive arthritis care, NSAIDS, glucosamine, and elbow sleeves can all help the pain. Steroid injections can also help with the pain. However, none of these interventions will halt the progression of arthritis. Surgical therapies include arthroscopic or open capsule release and removal of loose bodies and heterotopic bone. They are aimed at increasing motion and decreasing symptoms. If these do not help, the ultimate surgical treatment for elbow arthritis is a total elbow replacement.

Elbow Arthritis

Dupuytren’s is not actually a disease, but rather it is a disorder. It is a benign (non-cancerous) proliferation of tissue in the hands that may cause a contracture. This contracture and proliferation starts in the palmar fascia. This tissue in Dupuytren's is made up of a disproportionate amount of type III collagen. Type III collagen is the collagen in wound healing and has contractile properties. The condition in inherited, occurring mostly in white people of northern European descent. It has been called the “Viking Disease” for this reason.

Dupuytren’s usually starts with a painless bump. Often, those affected notice a lump or a “pucker” of the skin in the palm. With time, these lumps may grow or proliferate causing a contracture. Dupuytren’s does not hurt unless one tries to stretch out a contracture. As contractures worsen, patients complain of the inability to place their hands in certain positions.

The most common patient with Dupuytren’s is a white male in the sixth decade of life. It can occur, however, as early as the third decade in women. There is a strong genetic basis for Dupuytren’s. Some people get Dupuytren’s at an early age. When presenting young, Dupuytren’s tends to be aggressive.

Many times, patients are told that they do not require surgery. A painless bump or a ‘cord’ does not need intervention if it does not cause a contracture. Indications for intervention are a contracture of the metacarpophalangeal joint (knuckle) of 40° or any contracture of the proximal interphalangeal joint (the first joint of the finger). Surgery or enzyme injection can treat the contracture. Nothing will "cure" a patient of Dupuytren’s. The decision for which type of treatment will be made depending on the level of the contracture and the severity of the contracture.

Xiaflex: Xiaflex is a clostridium toxin. It cleaves type III collagen and works well to disrupt cords and can help to straighten fingers in those with Dupuytren’s contracture. It is a surgical procedure. Early reports have shown it to be about equal long-term in safety and recurrence to surgical treatment. More recent reports have shown it to be less effective long-term and have higher complications than surgical treatment and needle aponeurotomy. However, we no longer use Xiaflex due to its complications and expense.

Aponeurotomy: Aponeurotomy is a procedure done in the office. Under local anesthesia, a small needle is used to break up the cords. This allows the finger to straighten. This is used in minor cases and cases primarily with an MP contracture. A splint is worn for three weeks at night. Sometimes this does not achieve full correction.

Surgery for Dupuytren's: Intervention is indicated when one can’t use the hand appropriately and if the PIP joint is affected. Surgery is performed as an outpatient. Many times, patients will require therapy after surgery. Surgical outcomes are affected by the degree of contracture and the length of time the contracture has been present. Surgical correction of a 90° PIP contracture averages 45° residual contracture long term. This is the reason for intervention before the contracture is severe.

Dupuytren’s Contracture

The triangular fibrocartilaginous complex (TFCC) is a soft tissue structure located on the small (pinky) finger side of the wrist. It is the primary stabilizer of the wrist in pronation and supination (rotation). It also cushions and supports the small bones of the wrist, especially while the hand is gripping. An injury to the TFCC can cause chronic wrist pain, but, fortunately, successful treatment does not depend on the chronicity of the injury, so patients with long-standing pain can often get better.

TFCC tears cause pain on the “ulnar side” of the wrist, the side opposite the thumb. It sits directly on top of the ulna bone, the small bone in the forearm. The radius rotates around the ulna when you pronate (palm down) or supinate (palm up) the hand. The most common symptom of a TFCC tear is pain and weakness at end range supination, with grip, and when bearing weight on the affected arm. There also can be numbness and tingling radiating toward the small finger.

Outcomes for the nonsurgical acute casting of TFCC tears is excellent. Unfortunately, the only patients who are typically seen early enough for this type of treatment are high-level athletes. Surgical treatment for traumatic tears is generally better than degenerative tears. As in most orthopaedic injuries, younger patients do better than older patients. The good news is that it doesn’t matter how long a TFCC has been injured; surgery has been performed on patients who have had tears for more than eight years with excellent results.

TFCC Tears

De Quervain syndrome is a tendonitis of the first dorsal extensor compartment sheath, which is located at the wrist. It is a very common cause of wrist and thumb pain.  In this condition, the tendons that move the thumb become swollen and inflamed and have difficulty gliding through the first dorsal compartment. This constriction, in turn, leads to even more inflammation, further progressing the condition.

De Quervain’s is a common overuse tendonitis. It can happen in anyone that performs repetitive activity. It is also common during or after pregnancy—which is why it is also sometimes called “mommy thumb.” Most often, however, the cause is unknown.

The vast majority of the time, a simple injection followed by a period of rest will alleviate De Quervain’s syndrome. We generally use a simple brace over a three to four-week period following the injection. If the injection is unsuccessful in alleviating symptoms, a simple surgical procedure may be required. This is done on an outpatient basis and even can be done under local anesthesia in the office.

De Quervain’s Syndrome

The radial head is the most proximal portion of the radius bone and is located on the outside or lateral aspect of the elbow. It is made up mostly of cartilage and acts as a secondary stabilizer to elbow stress.

Radial head fractures almost always result from a fall on an outstretched arm, when the forces impact the radial head and cause injury. Often there is an associated ligamentous injury. The worse the radial head fracture is, the more likely there is to be a ligament injury as well.

They can occur in kids as well as adults. Most commonly, they occur in postmenopausal women after a routine fall due to osteoporosis. Radial head fractures also happen with high energy falls (ice, stairs, ladders), where they often have other fractures or ligament injuries associated with them.

Radial head fractures are treated non-operatively or operatively. Individuals with a non-displaced fracture with NO BLOCK to motion or MECHANICAL symptoms can be treated in a sling. There is often a ligament injury associated with the fracture, so a slow increase in activity is required. Individuals with a block to motion or an articular step-off are treated surgically. If there are only one or two fragments to the fracture, it is reduced and fixed with screws. Often, the fracture is in too many pieces to ensure healing. In this case, it will be replaced with a metal end cap. This metal cap is called a radial head arthroplasty.

Radial Head Fractures

Lateral epicondylitis “Tennis Elbow” is an age-related pain phenomenon that exists at the lateral side of the elbow. The wrist extensor muscle, called the extensor carpi radialis brevis (ECRB), inserts on the lateral epicondyle of the elbow. This muscle stabilizes the wrist in extension and more importantly gives it the strength and stability necessary for a “power grip.” It is thought that degeneration or tearing of the tendon, either acutely or over time, at the attachment to the elbow bone is the cause of symptoms of lateral epicondylitis. However, the exact pathophysiology of symptoms is unknown.

One of the classic symptoms of lateral epicondylitis is pain with pressure on the bony prominence of the elbow. Lateral elbow pain with power grip and pain with wrist extension are also hallmarks of lateral epicondylitis. There is often pain with passive wrist flexion as well.

One of the most common questions we hear regarding lateral epicondylitis is “I don’t play tennis, why do I have tennis elbow?” You have to keep in mind that this nickname is just that, a nickname; the condition is by no means limited to people who play tennis! Lateral epicondylitis is most common in individuals between the ages of 35-65 years old, regardless of their activity level. Sometimes a patient will report a sudden increase in pain, or it can be a more insidious onset. Furthermore, lateral epicondylitis is thought to be an overuse injury, but the actual pathogenesis is not fully understood.

Even in the evidence-based literature, there are hundreds of papers studying different treatment modalities for lateral epicondylitis, but almost all treatment results are equal to placebo (in essence, doing nothing). This includes bracing; injections of blood, platelets, or bone marrow; shock wave treatment; ultrasound-guided methods, etc. We do know that steroid injections into the elbow are worse than doing nothing and anti-inflammatory medications won’t work because lateral epicondylitis is not an inflammatory condition.

What is Thumb Ulnar Collateral Ligament Injuries?

The thumb metacarpophalangeal joint contains two important ligaments: the ulnar collateral ligament, which is on the pinky side of the thumb, and the radial collateral ligament, which is on the free side of the thumb. These collateral ligaments are critical for the stability of the thumb and for pinch and grip activities of daily living. The ulnar collateral ligament to the thumb is a complex ligament, comprised of the UCL proper and the accessory UCL. Together, they stabilize the thumb for pinch and grip activities; without this ligament, you would have very little pinch or grip strength and very poor overall dexterity.

UCL injuries were originally called “gamekeepers’ thumb,” although a more apt name would be “skiers’ thumb” because skiing is one of the most common mechanisms of injury. However, any blow to the inside of the thumb can cause the ligament to tear. It can also be weakened over time by the degenerative aging process. There is also a serious complication of UCL injuries known as a Stener lesion, in which the ulnar collateral ligament is torn, displaced and ultimately caught between the muscle that moves the thumb and the thumb bone. If this happens, there is no chance for healing, even if the tear is caught acutely and casted immediately. The ligament simply can’t get itself back into place if it is stuck beneath the muscle.

Partial tears and minimally displaced tears can be treated in a cast, which is worn for four weeks followed by a removable splint until motion and stability are returned. Complete tears that are displaced are treated surgically. This procedure requires your surgeon to surgically reattach the ligament. Most everyone can get back to the same level of function after surgery, even those who have been injured chronically. Oftentimes, patients will present with instability long after an injury. Fortunately, these injuries can usually be treated by mobilizing the ligaments and performing a primary repair; sometimes, a graft is used. In any case, these patients usually have good success. If a UCL injury is not treated, the metacarpophalangeal joint will become arthritic due to prolonged instability. Once the joint is arthritic, the only treatment is an arthrodesis or fusion of the joint. An arthrodesis is well tolerated in this joint, but a reconstruction of the UCL is obviously a much better treatment option.

Thumb Ulnar Collateral Ligament Injuries

The extensor tendons run along the back of the hand and wrist and extend the fingers. These are tendons you see on the back of your hand when you flex your fingers. The muscles for the extensor tendons attach in the forearm and go through tight compartments and pulleys on the back of the wrist before inserting on the finger.  The index and small finger have two tendons, the long and ring fingers only have one extensor tendon, and the thumb has two extensors, but they attach at different joints.

Traumatic injuries or lacerations can easily injure extensor tendons because they are so close to the skin. They can also rupture as a result of excessive swelling from a fracture or rheumatological condition.

Extensor tendon injuries are usually easier to treat than flexor tendon injuries, and they have better postoperative results. Acute lacerations are treated with a primary repair, and ruptures are typically treated by transferring one of the extra tendons to the injured one. The long thumb extensor tendon is the most common site of rupture. In this case, we take the extra index finger tendon and transfer it to the thumb. In addition to occupational therapy, it is crucial to have a therapist make a custom splint for the patient that accounts for their individual level of injury to increase the chance of optimal outcomes. We often send the patient to the therapist before surgery to get acquainted with the process and to make a splint.

Extensor Tendon Injuries

Radial Tunnel Syndrome, also known as radial neuritis, is a confusing and challenging condition affecting the terminal branch of the radial nerve in the arm, the posterior interosseous nerve.  It is often misdiagnosed as lateral epicondylitis (tennis elbow) due to the prevalence of that condition. However, this condition is a constriction or irritation of the posterior interosseous nerve in the proximal, lateral arm.

Pain in the proximal lateral forearm is the most common symptom of radial tunnel syndrome. There is usually not numbness associated with the condition.  Radial tunnel syndrome can occur at the same time as lateral epicondylitis, making the diagnosis more confusing. However, the pain is more distal, or toward the hand, than tennis elbow. There is pain with grip, activities and fine control of the fingers. We do not know definitively what causes radial tunnel syndrome, but we believe the posterior interosseous nerve is compressed at the proximal border of the supinator muscle.  This muscle has a thick, fibrous tendon-like border that the nerve must travel under, and as the band becomes thicker and therefore less compliant, it can cause constriction of the nerve. Some less common causes are ganglion cysts in the elbow and vascular malformations.

Patients are usually 35-65 years of age, and men and women are affected equally.  Radial tunnel syndrome can occur in tennis players and in golfers.  It also happens in those with true overuse conditions with repetitive wrist motion, especially rotation.

Generally, physical therapy works most of the time to treat radial tunnel syndrome.  Aggressive massage of the area combined with specific exercises will cure radial neuritis most of the time. Surgery is reserved for patients who do not get better with therapy or those with significant weakness, which is a sign of a much more severe compression.  Surgery consists of exploration of the nerve and release of the proximal supinator muscle. Some patients will get a temporary worsening of the weakness with surgery, but this almost always recovers.

Radial Tunnel Syndrome

Little Leaguer’s elbow is an injury to the growth plate on the inside of the elbow, which is known as the medial epicondyle. Growth plates are areas of long bones that are comprised of cartilage, the same soft tissue that makes up your nose and ears. This soft tissue is what ultimately allows for the longitudinal growth of bones as they develop and grow. Unfortunately, because it is made up of cartilage, the growth plate is the weakest part of a growing bone. In Little Leaguer’s elbow, stress to the medial elbow, or medial epicondylar growth plate, can cause injury.

The most common symptom of Little Leaguer’s elbow is elbow pain with a loss of velocity. The injury usually develops during an accelerated period of growth. Longer arms mean more torque, which, coupled with a weaker growth plate, can lead to damage. Therefore, any symptom of pain in a young thrower should result in cessation of pitching and rest. If the pain persists, then an evaluation by a trained orthopedic surgeon should be the next step.

Of course, to have an injury at the growth plate, one must be growing, so this injury typically occurs in young individuals who are rapidly developing. Overuse is thought to be the most common underlying cause of the injury; to that end, year-round baseball, playing for multiple teams, and not tracking pitch counts are the most common offenders. Most kids with this problem already know they are pitching and throwing too much, so they will often downplay their activity level. Once an individual stops growing, their growth plates close and are finally comprised of solid bone.  At this point, excess stress on the medial elbow will cause ligament damage known as a ‘Tommy John’ injury.   The most common age for Little Leaguer’s elbow is between 10-14 years old because most boys’ growth plates usually close by age 14, and they typically are not able to throw with enough velocity to cause an injury before age 10.

One word: education. With a better understanding of the pathology of this condition, we can stop the offending activities before they can cause injuries.  Pitch counts, rest, rotating pitchers, and regular evaluation of throwing mechanics are critical. However, it is essential to know that even if you do everything right, a young boy can still develop Little Leaguer’s elbow. Once a diagnosis of Little Leaguer’s elbow is made, we will generally cast the elbow because it is tough to keep a preteen boy from throwing. We have found that the most effective way to enforce rest is with a long arm cast. Return to play is usually six to eight weeks, but can be longer. After the resolution of symptoms, coaches and trainers should initiate a throwing program as the player slowly returns to sport. Once the player has returned to sport, the constant evaluation of throwing mechanics is essential to ensure that the injury does not persist.

Little Leaguer’s Elbow

A bursa is a fluid-filled sac that can be found in areas of the body that require the skin or tendons to glide. Common sites include the elbow (olecranon), the knee (patellar) and the shoulder (rotator cuff). Olecranon bursitis is the inflammation of the olecranon bursa. It is generally referred to as any swelling on the posterior elbow.

There are three primary causes of olecranon bursitis: trauma, inflammation, and infection. If the elbow is injured and there is bleeding in the bursa, olecranon bursitis can occur. Prolonged pressure from a traumatic event can also have the same effect. Second, patients with gout, rheumatoid arthritis or other inflammatory conditions can inflame the bursa and cause olecranon bursitis. Finally, an infection of the bursa will cause the sac to fill with fluid.

A non-infected bursa can be treated with the use of an elbow sleeve and, if necessary, an aspiration to remove excess fluid. Oftentimes, an aspiration is needed to diagnose infection or gout. A chronic bursa or one that has been infected before is usually treated with surgical excision. This requires patients to use a splint, followed by an elbow sleeve, for three to four weeks. In the case of an infected bursa, the infection must be controlled, which requires antibiotics and immobilization. In the case of a severe infection, this can require hospitalization and emergent surgery, combined with strong antibiotics.

Olecranon Bursitis

Cubital Tunnel Syndrome (CTS) is a compressive neuropathy of the ulnar nerve at the point behind the inside of the elbow where the nerve travels through the cubital tunnel. A compressive neuropathy is a progressive injury to a nerve caused by constant, unrelenting pressure; as the condition progresses, the outer covering of the nerve, which is called the myelin sheath, is injured due to a lack of blood flow. Small nerve fibers, those that conduct light touch and temperature, are affected first. Larger fibers, like those that conduct impulses to muscles, are affected later with chronic progression of the injury.

The most common presenting symptoms of cubital tunnel syndrome are numbness and tingling in the digits innervated by the ulnar nerve. These may be especially present at night time, often waking the sufferer up from sleep. Some people also complain of weakness, loss of dexterity, and a problem with consistently dropping objects.  Fine motor activities of the hand are also affected because the ulnar nerve controls all the small muscles of the hand. This can make typing and writing very difficult.

Cubital tunnel syndrome is often related to elbow position; to that end, sleeping with the elbow bent is the most likely culprit. Prolonged elbow flexion while typing or driving can also worsen symptoms. Like carpal tunnel syndrome, cubital tunnel syndrome often gets worse as individuals age and soft tissues become less compliant and less able to tolerate compression. Furthermore, people with diabetes, thyroid disorders, and obesity are more prone to compressive neuropathies. Finally, an estimated 10% of the population has a naturally subluxing ulnar nerve, which can be exacerbated by rapid elbow movements—like lifting weights, baseball, tennis—and this can cause symptom progression as well.

Mild cubital tunnel syndrome is treated with nighttime splinting and periodic reassessment to ensure there is no progression. The most reliable splint is an elbow pad or even a children’s knee pad worn backward so that the pad is anterior to the elbow. Either of these times, when worn while sleeping, can often relieve symptoms in mild compression on their own. However, in some cases, workplace and activity modification may also be required. Moderate and severe ulnar neuropathy is usually relegated to surgical treatment. One recent study done at Harvard demonstrated that severe ulnar neuropathy did improve with surgical treatment, but not to ultimately to normal levels. Therefore, surgical treatment before progression to severe disease is paramount. We treat patients surgically by releasing the nerve and placing it anterior to the elbow, allowing the nerve to be unaffected by the elbow position. Following surgery, patients are treated in a posterior elbow splint for two weeks. From week two to four they are relegated to limited activities but are encouraged to progress to activities as tolerated by four weeks post-op.

Cubital Tunnel Syndrome

A bunion, medically termed hallux valgus, occurs when the big toe leans too far into the second one and causes a swelling on the side of the big toe joint. Forming on the base of metatarsophalangeal joint (MTP) of your big toe, a bunion is a bony bump that forces your big toe to grow abnormally big and stick out.

Bunions can be various sizes and some aren’t even particularly painful. However, it is possible for the big toe to put pressure on the second toe, causing what is known as a hammer toe. It is also possible for the first two toes to cross over, resulting in difficulty in walking.

Other than the noticeable bony bump on the base on the outside of your big toe, other symptoms of bunions include:

Soreness or redness surrounding the big toe joint.

Restricted and limited movement of the big toe.

Calluses and corns, which may develop when the first and second toe overlap.

Skin thickening around the big toe joint.

Bunions generally occur when the big toe leans too far over into the second toe. The area swells and as shoes begin to rub against it, and inflammation and pain results. Bunions tend to be genetic, therefore many people who suffer from the condition have a family history already.

Individuals who are prone to bunions should never wear tight footwear. It’s this factor that results in the condition being far more of an issue for females than males. Pointed-toe, tight, and high-heeled shoes are not the primary cause of bunions, however, they can be a contributing factor.

Other causes of bunions include muscle imbalances and foot injuries. Arthritis, especially inflammatory types, such as rheumatoid arthritis, may also be a causal factor in developing bunions.

A Pensacola foot and ankle specialist can identify a bunion by a physical examination. This physical examination may reveal a bony bump, redness, swelling, and limited range of motion, which are hallmark signs of bunions. An X-ray will show the extent of the bunion and whether there is any associated arthritis in the affected area.

Treatment options for bunions including conservative non-surgical treatments and surgery.

As many as 50 percent of all bunion sufferers do not require surgery. Non-surgical treatments aim to prevent the development of ulcers and pressure sores, as well as relieve pressure on the foot.

In many cases, purchasing new, well-fitting and comfortable shoes alleviates pain. A Pensacola orthopedic specialist can also prescribe an orthotic. This is a device inserted within footwear, which can prevent the condition from deteriorating.

Other non-surgical treatments include ice, rest, steroid injections, and medications, as well as taping, padding, and/or splinting.

For some, surgery is the only way to correct their bunions and restore proper function to the big toe. Surgical procedures for bunions correction may include:

Removals of swollen tissue surrounding the big toe joint.

Removal of part of the bone to straighten the big toe.

Straightening of the abnormal angle of the big toe.

Joining of the bones of the affected joint.

For many years, bunion surgery had the reputation of being incredibly painful. Nowadays, however, modern surgery is far less invasive and more sophisticated. Each patient undergoing bunion surgery is assessed on their lifestyle as well as on the extent of the deformity of their bunion.

The best approach in terms of outcome, therefore, is to have a multi-disciplinary team of specialists working in tandem in order to achieve positive and lasting results.

Since you carry most of your weight and your joint flexes while you walk with every step, walking becomes difficult and painful when you have a bunion. This worsens the bigger your bunion is.

Narrow, pointed or tight shoes can cause bunions. Avoid high heels, especially those that have heels higher than two inches. These types of shoes also put you at risk of forming bunions. Tight footwear can contribute to the swelling and pain of bunions. Those complaining of bunions, tend to be those wearing closed shoes.

If your bunion is causing you pain or is disabling you and you've already tried conservative treatments with no luck, you may need surgery. Your orthopedic surgeon may perform a bunionectomy if your bunions are mild. This is where your North Florida Bone & Joint Specialists - Ankle and Foot Center orthopedic surgeon shaves off any extra bone from your first metatarsal bone on its outside. They then realign your tendons, ligaments and muscles of your big toe.

If you have a moderately deformed bunion, your surgeon will likely cut your bone that's near your metatarsal head in order to place it into the correct position. Pins and screws will hold your bone in place while you're healing.

If your bunions are severe, your surgeon cuts the extra bone of the first metatarsal head away as well as the bone at your first wedge-shaped metatarsal base.

You may be seen by a podiatrist who practices podiatric medicine. They specialize in diagnosing and treating ankle and foot problems, including bunions. However, you may need to see an orthopedic specialist or surgeon, depending on the severity of your bunion.

To prevent bunions, being proactive is key. Learn your risk factors and if you have any mechanic issues with your feet.

Your podiatrist will analyze your foot, the wear pattern of your shoes and your stride if you're unsure if you have an issue. They'll then provide you with an honest evaluation.

Be sure you're making the right shoe choices. Women shouldn't wear footwear with high heels as much as possible. Ensure your shoes have a deep, wide toe box. Shoes shouldn't crowd or squish your toes. Purchase shoes that have rocker soles which will take the pressure off the area where your bunion is.

Regularly check your feet. Look for any swelling, redness or discoloration. Check for stiffness by flexing your toes. Call us if you notice any of these signs if they persist for several days.

Women commonly get bunions. People who wear shoes that are closed get bunions more than those who are barefoot. Arthritic diseases like RA and abnormal bone formation of your foot at birth are both risk factors. People who perform ballet tend to get bunions often.

Bunions may cause sores and blisters due to them rubbing against your shoe on the inside. If you don't have these wounds treated, they can become infected and even lead to life-threatening complications.

If you notice a bunion and treat it early, you can slow the deformity down or even stop it. Cold packs, rest and other palliative self-treatments are good. Large pharmacies or orthopedic shoe stores sell silicone bunion shields. While they don't correct the issue, they do relieve pain from bunions.

Bunions

The space between the top of the shoulder (the acromion) and rotator cuff tendon is known as the subacromial space. If pain occurs when the humerus is rotated inward it is known as shoulder impingement syndrome. When the arm moves to certain positions, the tendon and the bursa are pinched and trapped between the top of the acromion bone and the humerus bone. Shoulder impingement syndrome can cause micro tearing of the rotator cuff and gradual degeneration. Over time, impingement syndrome can progress to a full tear of the rotator cuff.

As a result, the tendons of the rotator cuff become inflamed. This condition can be caused by a number of things, including:

An injury during a motor vehicle accident

Playing sports that involve excessive overhead use of the shoulder, including swimming, weightlifting, tennis and baseball

Shoulder impingement is also known as swimmer’s shoulder, tennis shoulder and rotator cuff tendinitis.

The symptoms of shoulder impingement syndrome include one or several of the following:

Minor pain, which presents itself with both activity and rest

Pain that radiates from the front of the shoulder to the side of the arm

Sudden piercing pain with lifting and reaching movements

As shoulder impingement syndrome progresses, the symptoms tend to increase, and include:

Difficulty participating in activities that require the arm to be placed above the head or behind the back, such as combing the hair or putting on a jacket or shirt

The causes of shoulder impingement syndrome vary, and can include:

Repeated stress to the shoulder, which is caused by activities that involve throwing or raising the arm

Most commonly occurs in young athletes and the middle-aged. Athletes who participate in swimming, baseball, tennis, and weightlifting, and construction workers whose jobs involve repetitive lifting or constantly raising the arms above the head

Anatomical factors can also place a person at greater risk of developing this condition, such as the shape of the acromion or the degenerative changes that some people experience. Poor posture and weak or imbalanced shoulder musculature can also lead to impingement syndrome.

Initially, your doctor takes your full medical history and performs a physical examination. During the physical examination, you will be asked to:

Move your arm above your head and behind your back, on your own.

Relax your arm while your doctor moves your arm above your head and behind your back.

X-rays are routinely obtained and MRI scans are sometimes useful in diagnosing shoulder impingement syndrome, as these scans allow your doctor to rule out arthritis or rotator cuff tears as a cause of the pain and limited motion.

Non-surgical and surgical treatments can be used for impingement. The vast majority if shoulder impingement can be treated nonoperatively with PT to correct imbalances of the muscles around the shoulder, and occasionally steroid injections.

Non-steroidal anti-inflammatory medicines

Surgery may be recommended when non-surgical methods aren’t effective. Arthroscopic surgery performed by an orthopaedic surgeon is minimally invasive and re-creates space for the rotator cuff to move smoothly. Inflamed bursa that surround the rotator cuff tendon are also removed.

Generally, physical therapy is recommended during recovery from impingement surgery. After surgery, your arm may be placed in a sling to limit movement and provide support for a few days. A rehabilitation program will be recommended by your doctor, and will address your specific needs, and includes exercises that improve the range of motion and strengthen the arm. It usually takes between 6-12 weeks to completely heal.

Why does shoulder impingement hurt more at night?

Why shoulder impingement hurts more at night isn't completely understood. Inflammation could be part of the reason, which can occur when you hold your joint in one position for an extended period of time. When you hold your arm close to your body, you can restrict blood flow to your bursa and rotator cuff tendon.

Pain is sometimes associated with this position. When you're experiencing pain during the night, especially if you're a professional or high school athlete, it’s a definite red flag something's wrong, and you need to seek your doctor for expert care. However, even non-athletes can have shoulder impingements and experience pain.

Can shoulder impingement cause headaches?

Absolutely. Headaches could occur with shoulder and neck pain simultaneously. In fact, studies have shown that tension-type headaches often go along with increased tenderness in the shoulder and neck muscles.

When you have tender spots in your body's connective tissue or muscles, it's called "trigger points" and when touched, are painful. These trigger points may feel like knots, nodules or tight muscles.

Patients often describe the pain in tension-type headaches as a feeling of pressure in or around their head or like a band is tightening around their head. Research estimates up to 80 percent of adults have tension-type headaches. If you're experiencing these headaches with your shoulder impingement, Dr. O'Grady and his staff can help alleviate the pain they cause.

Where should I ice my shoulder impingement?

When you get any new muscle injury, your first step is to reduce the swelling, inflammation and pain associated with it. You may be tempted to use heat on your sore shoulder, but during the first seven days after you are injured, you'll want to use ice only. Ice helps reduce your inflammation, swelling and pain. Apply the ice to your skin for around 15 minutes; if needed, wrap the ice bag in a towel to avoid irritating the skin.

Will steroids or acupuncture help shoulder impingement?

Yes. While your orthopaedic surgeon at North Florida Bone & Joint Specialists treats most shoulder impingements with physical therapy, they do use steroid injections occasionally. Acupuncture may also help to manage pain and reduce inflammation if you have an acute shoulder impingement.

Yes. Taping helps align your shoulder back to its normal position and provide space for your injured structures to heal.

Shoulder Impingement

The shoulder is the most mobile joint in the body. Its ability to function properly relies on the strength of the muscles and ligaments that allow it to move. The rotator cuff is one of the most crucial components of the shoulder.

The rotator cuff enables the muscles to lift and rotate the bone of the upper arm (the humerus.) These muscles are located under the acromion – a part of the shoulder blade – and as such, are prone to damage. When the rotator cuff is damaged, it tears, and this tearing can cause extreme pain and compromise the strength of the shoulder, limiting the use of the shoulder and the entire arm.

A torn rotator cuff can result from a traumatic event, or it can tear slowly over time. The primary symptom of a torn rotator cuff is pain and reduced range of motion; however, other symptoms may present and can vary. Additional symptoms of a torn rotator cuff include:

Difficulty sleeping, especially when lying on the affected shoulder

Restricted motion and difficulty completing tasks that require reaching, such as combing your hair, or trying to scratch your back

Feelings of instability in the shoulder and/or arm

A torn rotator cuff can either be the result of a traumatic injury to the shoulder or can be caused by the progressive degeneration, (wear and tear) of the muscles. Common causes of a torn rotator cuff include:

The development of bone spurs around the shoulder blade

The following factors can increase the risk of a torn rotator cuff:

As you age, your risk of tearing your rotator cuff increases. This condition is most common in people over the age of 35.

Sports that require the use of repetitive arm motions can increase the chances of tearing the rotator cuff. These sports include but are not limited to, baseball, tennis, archery, golfing, and surfing, and basketball.

These types of jobs often require the use of repetitive, overhead arm movements, which can damage the rotator cuff. House painters, construction workers, and carpenters, for example, are susceptible to torn rotator cuffs. In addition, firefighters and law enforcement officers are also susceptible.

There may be a genetic component that can increase the chances of developing a torn rotator cuff. Individuals who have family members who have developed this condition may be more apt to develop it themselves.

Although x-rays and MRIs are extremely valuable diagnostic tools for identifying a torn rotator cuff, history and physical examination is by far the most valuable way to evaluate the cause of shoulder pain. This examination will allow the doctor to determine the cause of the pain, and also evaluate if it is coming from locations other than the shoulder, such as the neck or the heart.

When properly diagnosed, the majority of shoulder pain can be treated successfully without surgery. Although some rotator cuff tears need to be fixed, many of these can also be treated without surgery.

This may include altering the activities that the patient participates in, physical therapy, anti-inflammatory medications, and injections.

Arthroscopy is a minimally-invasive surgical treatment for a torn rotator cuff. Arthroscopic treatment of rotator cuff tears allows for a much more thorough evaluation of all of the structures of the shoulder. An experienced shoulder surgeon will be able to fix even the most complex rotator cuff tears arthroscopically.

Dr. O'Grady uses the latest surgical techniques and methods such as the Rotation Medical Rotator Cuff Repair System.

There are four phases of recovery in returning to activities and sports:

You may experience stiffness and tenderness during recovery, especially in the first phase, which will improve with strength training and physical therapy. During each phase of recovery, it is vital to listen to the aftercare instructions provided by your medical professional.

Can rotator cuff tears cause pain in other areas of the body?

While rotator cuff tear pain is primarily thought to be located in the injured shoulder, it can also radiate along the outside of your upper arm all the way down to the thumb in the case of a supraspinatus tendon injury, or down the back of the arm in the case of a subscapularis injury.

When the infraspinatus muscle is injured, you may feel pain deep in the shoulder joint all the way to the outer part of your arm and hand. In some cases, you may feel pain and tingling in your fingertips resulting from your rotator cuff injury. Dr. O’Grady and his staff at North Florida Bone & Joint Specialists will work with you to determine the scope and severity of your rotator cuff tear so you can make informed decisions about what your next move will be.
