Pectoralis Major Repair With Unicortical Button Fixation And Suture Tape

Abstract

Although injuries of the pectoralis major muscle are generally uncommon, ruptures of the pectoralis major are occasionally seen in younger, more active patients who participate in weightlifting activities. These injuries usually occur during maximal contraction of the muscle, while in extension and external rotation. In the case of a rupture, operative treatment is advocated especially in young, active patients regardless of the chronicity of the injury. Various surgical techniques for reattachment of the avulsed tendon have been described, but bone tunnel and suture anchor repair techniques are most widely used. In this Technical Note, we present our preferred technique for acute pectoralis major rupture repair involving use of cortical buttons for tendon stump-to-bone fixation.

Pectoralis Major Ruptures: Tear Patterns and Patient Demographic Characteristics

“…We have also seen several new descriptions of surgical repair techniques for both acute and chronic ruptures. 3 , 6 , 7 , 22 …”

Clinical Outcomes of Pectoralis Major Tendon Repair with and without Platelet-Rich Plasma

“…Surgical repair techniques of PMT tears have previously been published 4 , 14 and are briefly reviewed here. The patient was placed in the beach-chair position with the operative extremity in a pneumatic arm holder (Tenet T-MAX Beach Chair and Spider arm positioner; Smith & Nephew, Memphis, TN) that positions the humerus in a flexed and internally rotated position.…”

Anatomic Pectoralis Major Repair With Intramedullary Anchor Fixation

“…Several repair techniques have been described including bone trough, transosseous fixation, suture anchor, and cortical button techniques; all have reported high rates of success. 7 , 8 , 9 , 10 The bone trough technique docks the pectoralis tendon within the humeral canal and provides excellent fixation; however, this technique requires a large cortical defect within the proximal humerus. The transosseous fixation technique requires multiple unicortical tunnels; this method is technically difficult and requires multiple drill tunnels, which increases the number of stress risers.…”
