Medial epicondylitis, also called golfer’s elbow, is tendinopathy of the medial common flexor tendon of the elbow due to overload or overuse. It may also be referred to as pitcher’s elbow, or termed tendinosis or epicondylalgia instead of epicondylitis. The medial epicondyle is the common origin of the flexor and pronator muscles of the forearm. The pronator teres, flexor carpi radialis, palmaris longus, and flexor digitorum superficialis originate on the medial epicondyle and are innervated by the median nerve. The flexor carpi ulnaris also inserts on the medial epicondyle and is innervated by the ulnar nerve. Together these five muscles share the same origin, forming the conjoined flexor tendon of the medial epicondyle of the humerus. This tendon is approximately three centimeters long, crosses the medial ulnohumeral joint, and runs parallel to the ulnar collateral ligament where it serves as a secondary stabilizer.
内侧上髁炎,也称为高尔夫球肘,是由于过载或过度使用导致的肘部内侧屈肌总腱的肌腱病。它也可能被称为投手肘,或者被称为肌腱变性或上髁痛而不是上髁炎。内侧上髁是前臂屈肌和旋前肌的共同起点。旋前圆肌、桡侧腕屈肌、掌长肌和指浅屈肌起源于内侧上髁,并由正中神经支配。尺侧腕屈肌也附着于内侧上髁,并由尺神经支配。这五块肌肉共同起源,形成肱骨内侧上髁的联合屈肌腱。该肌腱约三厘米长,穿过内侧尺肱关节,并与尺侧副韧带平行,在此处作为二级稳定器。
