Pectoralis Major Tear - Everything You Need To Know - Dr. Nabil Ebraheim

Dr. Ebraheim’s educational animated video describes the condition of pectoralis major tendon tear. Follow me on twitter: https://twitter.com/#!/DrEbraheim_UTMC Pectoralis Major Tear The pectoralis major insertion is just lateral to the long head of the biceps tendon. The pectoralis major insertion is just lateral to the long head of the biceps tendon. Insertion of the tendons in the proximal part of the humerus: medial to the long head of the biceps is the latissimus dorsi tendon insertion and medial to the latissimus dorsi is the teres major muscle insertion. The subscapularis tendon inserts superiorly on the lesser tuberosity, medial to the biceps tendon. Pectoralis major tear usually occurs in young, male weight lifters during bench pressing from eccentric contraction or lengthening of the muscle. Usually there is pain around the shoulder area, and the patient will feel a “pop” in the shoulder area while performing the bench press. There will be discoloration and burning over the pectoralis into the axilla. There will be swelling, ecchymosis and a palpable defect. The patient will have loss of contour of the axillary fold. MRI will confirm the diagnosis, will localize the site of the tear, and will also differentiate between partial and complete tear. Tendon avulsion is the most common type of injury to the pectoralis major muscle, and the tear is usually a complete tear. Hemorrhage and edema at the level of the proximal humeral shaft indicates a pectoralis major tendon rupture. To treat, reinsert the involved tendon into the humeral shaft, lateral to the biceps tuberosity. Chronic tears will need tendon graft, which is a more complicated surgery. The tendon is usually retracted, and the outcome is not as good as in case of acute repair.
