Isolated rupture of the teres major tendon.
Acute isolated rupture of the teres major is an uncommon injury. This article presents the first report of midterm subjective and objective functional results following nonoperative management of an isolated teres major rupture. A 30-year-old right hand dominant man presented after a waterskiing traction injury to his left upper extremity. On physical examination, the patient had swelling and retraction of the teres major at the lower scapular border, which was accentuated with resisted adduction of the extremity. His teres major attachment at the humerus was not palpable. Magnetic resonance imaging revealed an isolated teres major tendon rupture. The patient was treated non-operatively with a rehabilitation protocol emphasizing rotator cuff, periscapular, and latissimus muscle strengthening. By 3 months postinjury, the patient had returned to all of his usual sporting activities, despite a persistent muscle retraction deformity over the teres major. At 3-year follow-up, the patient had no subjective complaints in the injured extremity and excellent functional outcome scores. A mean 37 kg loss of internal rotation strength (as measured by dynamometer) in the affected extremity with the arm abducted to 90° existed, although this difference was not subjectively appreciable. Although previously published reports have presented various options for the management of teres major injuries, the present case demonstrates that nonoperative treatment can produce excellent midterm subjective results in spite of objective internal rotation weakness.
