Technique for repair of the subscapularis tendon.

Patients with sudden loss of active motion after an external rotation or hyperextension injury should be viewed with a high index of suspicion for a subscapularis tear. Exaggerated external rotation and the presence of a positive lift off or belly press test on physical examination combined with appropriate imaging studies will lead to an early diagnosis. Careful surgical repair combined with a thoughtful rehabilitation program will lessen both the length and degree of disability from this clinical entity.
