Golfers Elbow

Excerpt

Medial epicondylitis, also called golfer’s elbow, is tendinopathy of the medial common flexor tendon of the elbow due to overload or overuse. It may also be referred to as pitcher’s elbow, or termed tendinosis or epicondylalgia instead of epicondylitis.

The medial epicondyle is the common origin of the flexor and pronator muscles of the forearm. The pronator teres, flexor carpi radialis, palmaris longus, and flexor digitorum superficialis originate on the medial epicondyle and are innervated by the median nerve. The flexor carpi ulnaris also inserts on the medial epicondyle and is innervated by the ulnar nerve. Together these five muscles share the same origin, forming the conjoined flexor tendon of the medial epicondyle of the humerus. This tendon is approximately three centimeters long, crosses the medial ulnohumeral joint, and runs parallel to the ulnar collateral ligament where it serves as a secondary stabilizer.
