Q: What is Tennis Elbow ?

Tennis elbow, or lateral epicondylitis, is the most common injury in patients seeking medical attention for elbow pain. Exactly what causes tennis elbow is unknown, but it is thought to be due to small tears of the tendons that attach forearm muscles to the arm bone at the elbow joint. The muscle group involved, the wrist extensors, function to cock the wrist back. Specifically, the extensor carpi radialis brevis has been implicated in causing the symptoms of tennis elbow.
