Tennis elbow (lateral epicondylitis) is characterized by pain at the origin of the extensor carpi radialis brevis (ERCB) muscle from the lateral epicondyle of the humerus. A connection was found between tennis elbow and repetitive load in this area. In patients who suffer from elbow pain, tennis elbow is the most common cause, affecting 1-3% of the adult population each year. The diagnosis of tennis elbow is mainly clinical, based on medical history and physical examination. There are several possible treatments ranging from anti-inflammatory drugs and physiotherapy to various local injections (steroids, hyaluronic acid, etc.) and surgical treatment with debridement or release of the ECRB.
