The costocoracoid ligament: A case report

During routine dissection of a human cadaver, the costocoracoid ligament was observed as a thick, fibrous band extending from the ventral surface of the costal cartilage of the 1 rib to the coracoid process. It is part of the clavipectoral fascia and lies close to the costoclavicular space of the superior thoracic aperture, consequently affecting structures passing through it like the subclavian vessels and the brachial plexus. Abnormalities in the costocoracoid ligament may therefore result in clinical conditions, surgical complications and/or cosmetic deformities.This is one of the few papers describing the anatomy of the costocoracoid ligament in a cadaver, and aims to provide a better understanding of the topic. A better understanding of the anatomy and practical significance of the costocoracoid ligament could aid in better understanding of the anatomy of the surrounding region and improve the course of healthcare for relevant cases.
