TENNIS ELBOW (LATERAL EPICONDALGIA) Pain and tenderness over the lateral epicondyle of the elbow (or, more accurately, the bony inseion of the common extensor tendon) is a common complaint among tennis players - but even more common in non-players who perform similar activities involving forceful repetitive wrist extension. It is the extensor carpi radialis tendon (which automatically extends the wrist when gripping) which is pathological in tennis elbow . Like supraspinatus tendinitis, it may result in small tears, fibrocailaginous metaplasia, microscopic calcification and a painful vascular reaction in the tendon fibres close to the lateral epicondyle.
