TENNIS ELBOW
The injury leading to the disability is not uncommon in those who take much physical exercise, particularly lawn-tennis, whence the name TENNIS ELBOW. However, athletic sports in which strenuous and exact movements of the arm play an important part, are not the only causes of the trouble. The history of the affliction in those in whom it occurs in the course of their favorite exercise is almost invariably as follows: Immediately after a stroke, or occasionally some few hours or days afterwards, pain is noted in the elbow, usually the right, in the neighborhood of the external condyle. This pain may be so severe and sudden as to seem to paralyze the arm temporarily, so that all movements are performed with the greatest difficulty or not at all. This pain is usually markedly increased by extension of the forearm, not so much by flexion and may be intermittent or constant, and returns immediately the exercise is taken up again. Lesser degrees of pain or disability are noted in many cases. The pain is most sharply limited limited to the neighborhood of the external epicondyle of the humerus.
