Tight<unk><unk>  has been shown to be a contributor to chronic shoulder pain and chronic back pain. Because the<unk><unk>  connects the spine to the humerus, tightness in this<unk>  can manifest as either sub-optimal glenohumeral joint (shoulder) function which leads to chronic pain or tendinitis in the tendinous fasciae connecting the<unk><unk>  to the thoracic and lumbar spine. The<unk><unk>  is a potential source of<unk>  for breast reconstruction surgery after mastectomy (e.g. Mannu flap) or to correct pectoral hypoplastic defects such as Poland's syndrome. An absent or hypoplastic<unk><unk>  can be one of the associated symptoms of Poland's syndrome. Cardiac support For heart patients with low cardiac output and who are not candidates for cardiac transplantation, a procedure called cardiomyoplasty may support the failing heart. This procedure involves wrapping the<unk> s around the heart and electrostimulating them in synchrony with ventricular systole. Injury Injuries to the<unk><unk>  are rare. They occur disproportionately in baseball pitchers. Diagnosis can be achieved by visualization of the<unk>  and movement testing. MRI of the shoulder girdle will confirm the diagnosis.<unk>  belly injuries are treated with rehabilitation while tendon avulsion injuries can be treated surgically, or with rehab. Regardless of treatment, patients tend to return to play without any functional losses.
