Copectomy is a surgical procedure that involves the removal of a portion of the rib cage, specifically the costal cartilage and sometimes the ribs, to alleviate pressure on underlying structures or to treat various medical conditions. It is often performed in cases of thoracic outlet syndrome, severe trauma, or certain tumors. The goal of the surgery is to improve respiratory function, relieve pain, or enhance mobility. As with any surgical intervention, potential risks and complications should be considered.
