The Pectoralis major is a very powerful muscle that forms the chest prominence and. It moves the shoulder forwards and across your chest. It is best known as the muscle that you develop with the bench press exercise.
The pec major attaches to the humours bone (upper bone of arm) and is divided into two parts. The upper part is known as the ‘clavicular head’ and the lower part the ‘sternal head’, based on their origins from the clavicle and sternal bones respectively.
Surgery for Pec Major Tears:
The pec major muscle is not essential for normal daily shoulder function, but is important for strenuous activities. Patients who wish to return to active athletic and manual activities are likely to benefit from surgical repair. However, it is important to bear in mind that this is an uncommon injury and the literature is based largely on case reports, small series, and systematic reviews of these small series. There is a lack of high-quality good evidence for surgical versus non-surgical management and early versus delayed repairs. Outcomes in the literature are also presented heterogeneously, so it is difficult to compare them.
