Muscle Transfer for Shoulder Reconstruction in Erb's Palsy

Introduction: Patients with Erb's palsy have internal rotation deformity of the shoulder with loss of overhead elevation. These patients could be treated by derotation osteotomy or muscle transfer around the shoulder. Advantages of muscle transfer is that it is functional and rebalances the shoulder. The use of a posterior and transaxillary approach allows release of the subscapularis muscle fom its origin with the possibility of relocation of the posteriorly subluxated head and insertion of the transferred muscles directly at the insertion of rotator cuff to provide stability for the head of the humerus.
