Pectoralis Major Muscle Tear Diagnosed with Magnetic Resonance Imaging and Ultrasound-A Case Report

Traumatic tears of the pectoralis major muscle are rare, but they are becoming more prevalent as the numbers of both professional and recreational athletes increase. Pectoralis major injuries typically occur in active individuals who do manual labor or participate in sports. Wightlifting is by far the most common sport associated with pectoralis major ruptures. Diagnosis can usually be made based upon history and physical examination; however, ultrasound and magnetic resonance imaging are helpful tools in diagnosis and pre-operative planning. Specific treatment options should be based upon the severity of the injury and the patient's individual needs. Initial post-injury immobilization and subsequent physical therapy can contribute to a patient regaining full shoulder motion and being able to conduct normal daily activities. Surgery with repair of the pectoralis major rupture is able to restore normal chest-wall contours and muscular strength.
