The pectoralis major is the muscle one develops when doing a bench press exercise. It moves the shoulder forwards and across the body. It has two parts – the clavicular head and the sternal head which attach to the humerus bone.
The rupture of a pectoralis major is becoming more common due to an increase in power sports with weight training.
This muscle is important in strenuous activities and therefor repair is indicated.
The earlier the surgery is done, the easier it is. If it is left too late the tendon retracts and might become impossible to repair primarily and a tendon graft might be necessary.
