Medial epicondylopathy is the most frequent cause of medial elbow pain, but is 3-10 times less common than lateral epicondylopathy. (2,12-15) It is most prevalent in the fourth and fifth decade and affects men and women fairly equally.
A condition that may plague adults, particularly males in the 20-40 year age range, is avascular necrosis of the lunate. This has been termed Kienbock’s disease in reference to the doctor who first diagnosed the disease in 1910.
The Achilles tendon may be acutely strained or ruptured as the result of an excessive stretch or eccentric force. Consistent with other types of acute strains, Achilles tendon injuries may occur when the musculotendinous unit transitions from eccentric deceleration to concentric propulsion
Carpal tunnel syndrome (CTS) is caused by mechanical compression of the median nerve within the carpal tunnel. This compression causes local ischemia and results in sensory and/or motor deficits in the distribution of the median nerve.
Biceps tendinopathy describes a painful inflammation or degeneration of the tendon of the long head of the biceps. (1,2) The term “tendinopathy” may suggest either an inflammatory or degenerative origin. (3) In the case of a recent acute insult, inflammation (tendinitis) may be a valid explanation. However, current evidence suggests that many cases of tendinopathy occur without inflammation and are the result of chronic overload, which leads to microscopic tearing, failed healing and subsequent degenerative changes within the tendon. (3) Injuries that have been present over three months consistently demonstrate fibrosis and degeneration with very little inflammation. (3)
