Pectoralis Major Muscle Rupture Repair: Technique Using Unicortical Buttons

Abstract Over the past few decades, there has been increased awareness of pectoralis major muscle injuries necessitating further evaluation of management options and, in particular, surgical repair. Injury typically occurs when an eccentric load is applied to the muscle, such as with bench pressing, and failure usually occurs through the tendon. Although nonoperative management is sometimes appropriate, given the injury's propensity for young, active male patients, surgical intervention is often warranted. Because the injury typically occurs at the muscle-tendon interface, surgery focuses on repair of the avulsed tendon into its anatomic attachment site. We describe the use of a unicortical suture button to repair the ruptured tendon. This technique achieves the goals of strong fixation and anatomic repair of the tendon back into its native footprint.
