2024年2月27日 · A rare acute injury caused by avulsion of the pectoralis major tendon and usually seen in weightlifters. Diagnosis is generally made clinically and is confirmed with MRI studies. Treatment is usually surgical repair when presenting acutely.

2024年4月1日 · A ruptured pectoralis major tendon (sometimes referred to as a “pec tear”) occurs most frequently in men aged 20 to 40 while performing a bench press. Other activities commonly associated with pectoralis major injury include skiing, football, wrestling, rugby and direct trauma.

2016年9月17日 · In type 1 torn pectoral, the tendon of the pectoralis major tears directly off of the humerus – the easiest to fix. In type 2 torn pectoral the tear occurred where the muscle starts transitioning into a tendon – the muscle-tendon junction- harder to fix, but still possible. In type 3 pec ruptures, the tear is completely within the muscle itself.

2023年8月7日 · Traumatic injury of the pectoralis major most commonly occurs due to excessive tension on a maximally eccentrically contracted muscle. This setup typically occurs during the downward portion of a bench press, with the arm in the final 30 degrees of humeral extension and external rotation while pushing against heavy resistance.

2024年6月13日 · A pectoralis major tear happens when you injure your pec tendon or chest muscle. This type of injury is rare, and it typically happens to athletes or weightlifters.

Pectoralis major tendon rupture is a rare shoulder injury commonly seen in weight lifters. This injury is being seen more regularly due to the increased emphasis on healthy lifestyles.[1]

The injury occurs with excessive tension on a maximally contracted muscle and the most commonly occurs with the pectoralis tendon tearing away from the bone (tendinous avulsion). Classification of Injury

2022年11月29日 · Pectoralis major ruptures are uncommon injuries that have become more prevalent over the past 20 years due to increased participation in weight lifting. Patients often present with localized swelling and ecchymosis, muscular deformity, thinning of the anterior axillary fold, and weakness in adduction and internal rotation of the affected arm.

In this article we describe the clinical anatomy and the mechanism of injuries of PM and we review the surgical procedures for acute and chronic ruptures. Keywords: pectoralis major, rupture, surgical procedure. Pectoralis major (PM) muscle is the powerful dynamic stabiliser of the shoulder that acts as a flexor, adductor and internal rotator 1.

What causes a pectoralis major rupture? A pectoralis major rupture includes either a partial or total tear of the muscle or tendon. It is usually caused by activities that involve a large amount of force, such as bench press exercises during weightlifting.
