Reconstruction of Chronic, Retracted Pectoralis Major Tendon Tear With Achilles Tendon Allograft.

Rupture of pectoralis major tendon (PMT) is an uncommon injury, but its incidence has been increasing in the past 2 decades. Although open repair of the torn tendon is the preferred choice of treatment in acute and chronic cases, this often is not possible for chronic retracted tendon injuries. While several techniques have been described for PMT reconstruction, these allografts and autografts are often smaller and less thick than the native PMT. In this study, we describe the use of the Achilles tendon allograft with unicortical suture buttons for the reconstruction of a chronic and retracted PMT. Furthermore, the advantages and disadvantages of this technique are discussed.
