Lateral epicondylitis: review and current concepts

Lateral epicondylitis is a painful and functionally limiting entity affecting the upper extremity and is frequently treated by hand surgeons. The anatomic basis of the injury to the extensor carpi radialis brevis origin appears to be multifaceted, involving hypovascular zones, eccentric tendon stresses, and a microscopic degenerative response.
