Surgical treatment of pectoralis major muscle rupture with adjustable cortical button

Abstract

© 2016 Sociedade Brasileira de Ortopedia e Traumatologia Objective To assess the tendon reconstruction technique for total rupture of the pectoralis major muscle using an adjustable cortical button. Methods Prospective study of 27 male patients with a mean age of 29.9 (SD = 5.3 years) and follow‐up of 2.3 years. The procedure consisted of autologous grafts taken from the semitendinosus and gracilis tendons and an adjustable cortical button. Patients were evaluated functionally by the Bak criteria. Results The surgical treatment of pectoralis major muscle tendon reconstruction was performed in the early stages (three weeks) in six patients (22.2%) and in 21 patients (77.8%), in the late stages. Patients operated with the adjustable cortical button technique obtained 96.3% excellent or good results, with only 3.7% having poor results (Bak criteria). Of the total, 85.2% were injured while performing bench press exercises and 14.8%, during the practice of Brazilian jiu‐jitsu or wrestling. All weight‐lifting athletes had history of anabolic steroid use. Conclusion The early or delayed reconstruction of ruptured pectoralis major muscle tendons with considerable muscle retraction, using an adjustable cortical button and autologous knee flexor grafts, showed a high rate of good results.
