Reconstruction of the Pectoralis Major Tendon Using Autologous Grafting and Cortical Button Attachment: Description of the Technique

摘要

Total rupture of the pectoralis major muscle in athletes is not a common type of lesion, but with the quest for bodily perfection and muscular hypertrophy and the use of anabolic steroids, this injury has brought increasing numbers of weight-lifting athletes to the hospital. Although techniques have evolved over recent decades, chronic and acute lesions without reinsertion possibility still present challenging reconstructions for orthopedic surgeons. This study is a current prospective study involving 6 weight-lifting athletes who exhibited total rupture of the pectoralis major muscle over a 3-month period and had muscular retraction. The tendons were reconstructed using autologous grafting of the flexor tendons from the ipsilateral knee and attached to the cortical bone of the humerus using 2 endobuttons to maintain the grafts within the humerus for better integration between the tendon and the bone. Although this technique requires more follow-up, it represents a viable option for reconstruction of the tendon of the pectoralis major muscle in chronic and acute patients for whom reinsertion of the remaining tendon is not possible.
