Abstract: One hundred nine obstetrical palsy patients with defective shoulder abduction and
external rotation had subscapularis release and transfer of teres major to infraspinatus with
or without pedicle transfer of the clavicular head of pectoralis major to deltoid. The age at
surgery averaged 67 months (11-192) and follow-up averaged 36 months (12-80). Thirty-
nine cases had follow-up CT scan of both shoulders.
