Ossified Coraco acromial ligament: A rare anomaly with clinical significance

Susmita Saha, Neelam Vasudeva

Abstract :

 The Coracoacromial Ligament (CAL) is a strong triangular band, extending from the coracoid process to the acromion process. This ligament, together with the coracoid process & the acromion, form a vault for the protection of the head of the humerus. It is also one of the major components of Coraco acromial arch. Impingement of the tendinous cuff beneath this arch is an established cause of chronic shoulder disability mainly in rotator cuff impingement pathology. Anatomical texts allude to many variations in the morphology of the acromion process as well as coracoid process of the scapula but ossified CAL in dry bony specimen has not been mentioned very routinely because in the dry bone normally this ligament is not found. In the present study, we report a completely ossified CAL extending from the tip of the coracoid process to the undersurface of the acromial process in a single dry bony specimen in the osteology museum department of Anatomy, MAMC, New Delhi. Studies have been undertaken to define various morphologic pattern of this particular ligament in the cadavers but little anatomic information exists about the status of this ligament in dry bones. Moreover, most of the studies were based on western population; little attention has been paid to this anatomic issue in the Indian population. Though this type of anatomic information is thought to be one of the most important factors in the pathogenesis of impingement syndrome as it can press upon the supraspinatus tendon, so knowledge and awareness of such variations is extremely helpful to the orthopaedic surgeons for the diagnosis and management of impingement of shoulder joint.
