AbstractPectoralis major rupture is a very uncommon injury first time described by Patissier in 1822. Tears are classified on the type (partial and complete) or on the site (tendinous, myotendinous junction, intramuscular). Ruptures are reported in young high-performance athletes as results of eccentric contractions of the musculotendinous unit. The most probable mechanism in elderly patients is a brisk tearing movement applied to stiff atrophic muscle. Injuries generally involve the sternal portion; the localization to the clavicular portion is rare and can be misdiagnosed as muscle sprain. Preoperative planning include MRI as gold standard regarding operative versus non operative treatment decisions. Surgical repair is recommended in cases of complete tears because of loss of strenght in adduction, flexion and internal rotation. Aim of the current study is to describe the surgical repair of acute pectoralis major tendon rupture in 5 patients. Surgery was performed through a modified delto-pectoral approach; pectoralis major tendon was attached at its anatomic insertion using two metallic anchors. The patient as been immobilized in a sling for 30 days and then assisted physiotherapy begun; strenght exercises were allowed at 90 days. At a mean follow-up of 24 months results were excellent in all cases with restoration of strenght and coming back to previously sports activity.
