Humeral epicondylitis

Abstract

Abstract We concur with this opinion, but narrow our definition of tennis elbow to elbow pain that can be related to the extensor movements of the wrist joint. These extensors commonly attach to the lateral epicondyle, so the term lateral epicondylitis is preferable to tennis elbow, especially since the syndrome com monly occurs in non-athletes whose occupations involved repeated gripping activities, such as carpenters, The lateral epicondyle of the humerus is a point of origin for the wrist extensors, including extensor carpi radialis longus, extensor carpi radialis brevis, extensor digitorum, and extensor digitiminimi. These muscles attach jointly to the lateral epicondyle via a tendinous expansion known as the common extensor tendon, or extensor aponeurosis (Fig. 6.1). In addition, the supinator muscle partially attaches to the lateral epicondyle and lies underneath the wrist extensor muscles mentioned above
