Peroneal Tendon Instability , A Rare But Important Ankle Injury

Peroneal Tendon Instability

Ankle sprain is a common injury in Singapore athletes as well as the active adult. Most of the time, the ankle heals with a little care (rest, taping, ice). But one rare complication of lateral ankle sprains is a condition called peroneal tendon instability. A lateral ankle sprain means the side of the ankle away from the other leg is sprained. The two peroneal tendons go down the leg and around the back of the ankle bone. The tendons set down inside a tunnel formed by bone and connective tissue called the retromalleolar groove. A fibrous band (the superior peroneal retinaculum) goes across the tendon to hold them in the groove. […]

Ganglion Cysts

About ganglion cysts

Ganglion cysts are fluid-filled sacs. They can occur at any joint in your body, but are most common around the wrist. Ganglion cysts may also appear on the feet.

Ganglion cysts form when the natural lubricating fluid leaks out of a joint or tendon, making a little sac (or cyst).

Biceps Instability

Biceps instability takes the form of either frank dislocation or more subtle subluxation. As noted previously, the primary restraining structures holding the LHB in the bicipital groove are the medial sling and subscapularis tendon. Habermayer and Walch divided LHB dislocations into extra-articular or intra-articular. The much less common extra-articular dislocations dislodge from the bicipital groove […]

Biceps Tendinitis

Biceps tendinitis has been partitioned into primary tendinitis versus secondary tendinitis. Primary tendinitis involves inflammation of the tendon within the bicipital groove. To be considered primary, no other pathological findings (such as impingement, bony abnormalities within the groove, or biceps subluxation) should be present. It is considered an uncommon condition and should be thought of […]

Pathophysiology

Multiple classification schemes have been developed to describe disorders of the LHB tendon. These divisions have been only marginally useful in regards to diagnosis and treatment decisions. More important is to understand the various pathological processes involving the biceps tendon and how to treat each process accordingly. The three biceps tendon pathologies that we will […]

Small Tears Less Than 1 Centimeter

Smaller tears are easily missed as patients present with findings and symptoms consistent with impingement. Occasionally weakness is present, but even following the Neer test, significant weakness may not be detected.

These tears usually involve the supraspinatus tendon insertion, and pain is the primary presenting complaint. Examination usually reveals normal motion and strength.

After the […]

Tennis Elbow / Lateral Humeral Epicondylitis

WHAT IS TENNIS ELBOW OR LATERAL HUMERAL EPICONDYLITIS?

Tennis elbow is characterized by soreness or pain on the outside of the upper arm near the elbow. There may be a partial tear of the tendon fibers which joins the muscle to bone near their point of origin on the outside of the elbow.

HOW IS […]

Carpal Tunnel Syndrome

WHAT IS CARPAL TUNNEL SYNDROME?

Carpal tunnel syndrome occurs when the median nerve which runs from the forearm into the hand becomes pressed or squeezed at the wrist. This results in pain, weakness, or numbness in the hand and wrist, radiating up the arm.

HOW IS CARPAL TUNNEL SYNDROME DIAGNOSED?

A physical examination help determine […]

Rotator Cuff Injury

WHAT IS SHOULDER PAIN DUE TO ROTATOR CUFF INJURY?

Rotator cuff injury is the damage to the rotator cuff. This condition is one of the most common causes of shoulder pain.

HOW IS SHOULDER PAIN DUE TO ROTATOR CUFF INJURY DIAGNOSED?

Diagnosis is done through understanding the patient’s history of activities and symptoms of pain […]

Shoulder instability / shoulder dislocation

WHAT IS SHOULDER DISLOCATION?

A dislocated shoulder occurs when the humerus separates from the scapula at the glenohumeral joint.

HOW IS SHOULDER DISLOCATION DIAGNOSED?

Diagnosis includes physical examination where there is a significant pain, which can sometimes be felt past the shoulder, along the arm. The person is unable to move the arm from its […]
