Elbow

Lateral epicondylalgia (tennis elbow)

Mechanism
Overload of the common extensor tendon at the lateral epicondyle, usually in the extensor carpi radialis brevis tendon. Repeated forceful gripping with the wrist extended is the usual load.
Recognition
Point tenderness just distal to the lateral epicondyle, pain on gripping, and a positive Cozen test: resistance against wrist extension with the elbow extended.
Course
The -itis ending has been abandoned: histologically there is no inflammation but tendon degeneration. The course is long but favourable; most are symptom-free within a year, even without intervention.
