Chronic Pectoralis Major Muscle Belly Repair and Reconstruction With Achilles Allograft Augmentation

Abstract

Case: A 60-year-old man presented with a chronic right pectoralis major muscle belly tear of the lower sternal head that was missed and previously treated with tendon repair of the sternal and clavicular heads. The tear was repaired and reconstructed with an Achilles allograft. At the 1.5-year follow-up, the patient had excellent outcome scores on the Short Form Survey-36 and American Shoulder and Elbow Surgeons Scores, cosmesis, and strength. Conclusions: To our knowledge, this is the first report of a chronic pectoralis muscle belly tear reconstructed with an Achilles allograft, an uncommon injury traditionally treated nonoperatively.
