Abstract We present a new surgical technique for a pedicled teres major muscle transfer to improve shoulder abduction and flexion in children with sequelae of obstetric brachial plexus palsy. In addition we provide the clinical outcome in the first l7 operated children. Introduction Muscle weakness is a frequent sequela after obstetric brachial plexus palsy obpp and might be improved by muscle transpositions especially at the shoulder level 1 . The teres major muscle tmm is included in the technique described by Hoffer 2 to enhance active lateral rotation of the shoulder where this muscle should address the function of the infraspinatus muscle. We propose a single transfer of the tmm in selected conditions in children suffering obpp sequelae 1. when shoulder flexion and or abduction are weak against gravity active ROM less than 90 with a strength less or equal M3 2. when the tmm shows cocontractions during shoulder abduction mixed reinnervation of the dorsal cord .
