Pectoralis major transfer for scapular winging

Abstract

Scapular winging secondary to serratus anterior dysfunction is often initially misdiagnosed. When it is refractory to conservative treatment, tendon transfers are commonly prescribed. The principal goal of surgical treatment is to re-establish dynamic scapular stability to reduce pain and dysfunction. Multiple surgical reconstruction techniques have been described. Transfer of the sternal head of the pectoralis major muscle is the most commonly utilized technique. In this paper, we describe a minimally invasive technique using a hamstring allograft to augment the tendon to bone fixation of the sternal head of the pectoralis major tendon.
