Diagnosis, treatment, and rehabilitation of the thrower's elbow.

The overhead throwing motion generates enormous force in the elbow. Repetitive near failure loads lead to chronic adaptive changes and occasionally acute injury. The physician caring for the thrower must understand the complex anatomy and function of the elbow joint, along with the biomechanics of throwing, to accurately diagnose and treat elbow pathology. Evaluation of elbow pain in the throwing athlete must begin with a thorough and detailed throwing history including duration of symptoms, location of pain, timing during the phases of throwing motion, and associated symptoms. Physical examination should include inspection, range of motion, palpation, and specific tests to better define the pathology. A detailed history and physical examination will allow the astute clinician to obtain the proper diagnosis and start the appropriate operative or nonoperative treatment often without reliance on ancillary testing. Treatment and rehabilitation of these injuries must be tailored to the pathology present and focused towards a return to the athlete's activity.
