Modified latissimus dorsi and teres major transfer for external rotation deficit of the shoulder.

Variable impairment occurs following birth associated brachial plexus injury. Muscle transpositions have evolved in response to patient need for functional reconstruction. Loss of external rotation limits the ability to perform activities with the arm in an overhead position. A modification of the combined latissimus dorsi and teres major transfer is described by means of which increased excursion of the transfer may be achieved.
