Clinical correlation

Lateral epicondylitis ("tennis elbow")

It is a painful injury from repeated use of the superficial extensors of the forearm. The pain lies over the lateral epicondyle and runs down the posterior surface of the forearm; it worsens on opening a door or lifting a glass. Strong, repeated flexion and extension of the wrist strain the attachment of the common extensor tendon and inflame the periosteum of the lateral epicondyle.
