Pectoralis major rupture:

case report of an unusual rupture

Keywords: Case Reports, Pectoralis Muscles, Magnetic Resonance Imaging

Abstract

Although not very common, in the last 20 years, there has been a significant increase in reports of rupture of the pectoralis major, normally associated with the practice of physical activity in which intense contraction occurs and/ or the use of heavy loads exerting resistance on the muscle. In this case report we have a 51-year-old patient reporting pain in his right chest and right arm for 3 days after trying to fix his motorcycle’s handlebars. He had asymmetry of the pectorals, loss of strength in the right upper limb, difficulty moving and hematoma. Magnetic resonance imaging demonstrated complete rupture of the myotendinous junction of the pectoralis major, with tendinopathy with insertional and intrasubstantial infraspinatus fissures and tendinopathy with partial rupture of the subscapularis tendon. An orthopedic doctor recommended follow-up with the use of analgesic medication.
