Tennis Elbow (Lateral Epicondylitis)
Tennis elbow, or lateral epicondylitis, is one of the most common elbow injury seen. 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.
Tennis elbow often involves a tendon that inserts on the lateral epicondyle known as the extensor carpi radialis brevis. Pain is often elicited with wrist or finger extension, and it can radiate down the forearm. There are several treatments for tennis elbow, and it can be a difficult problem to treat.
Initial treatments include anti-inflammatories and avoiding causative activities. Braces or physical therapy can also be helpful. Injections, such as cortisone or platelet rich plasma can also be used. Percutaneous or open surgery can be done if tennis elbow persists despite conservative treatment.
