An Anatomical Study on Acromion, Coracoid and Glenoid Processes of Scapula

The current study involves the measurement of different dimensions of the three processes of scapula as well as determination their morphology.

The shape of the acromion plays a crucial role in impingement syndrome and the pathophysiology of rotator cuff disorders. Many surgical procedures involving the shoulder joint require the coracoid process. When developing glenoid components for total shoulder replacement, the dimensions of the glenoid process are critical. The current study was a descriptive study and included 42 unpaired human scapulae available in the departmental museum of Anatomy of a Medical College in Eastern India. Acromion morphology appears to have a predictive value for determining success of conservative or surgical treatment of shoulder joint impingement. Various open surgical and arthroscopic access to the shoulder revolve around coracoid process. So, its morphometry is of pivotal importance in surgeries involving shoulder joint. The current study will be of immense help in orthopaedic surgeries on the shoulder joint and in biomechanical engineering for designing implants for total shoulder replacement.

The results will be highly relevant in orthopaedic surgery and manufacturing shoulder prosthesis.
