Tennis Elbow - Lateral Epicondylitis

Tennis elbow, or lateral epicondylitis, is one of the most common elbow injury sports. Exactly what causes tennis elbow is unknown, but it is thought to be due to small tears of the tendons that attach the muscles of the forearm to the arm bone at the elbow joint.

The muscle group involved, the wrist extensors, function to cock the wrist back and stabilize the wrist while gripping such as a bat, racquet, or club.
