Abstract

The coracoid process is aptly defined as the “light house of the shoulder” since an important principle of shoulder surgery is to board an approach which is lateral to the coracoid process. This is done to evade the neurovascular structures passing medially; besides, many important tendinous and ligamentous attachments are anchored here. Loss or damage of any of the structures could lead to alterations in the structure of coracoid process. Therefore, a more comprehensive study of the morphology of coracoid process is needed.

Aim: To study the coracoid process of scapula and its clinical significance.

Material and Methods: The present study was conducted on 100 dry human scapulae. Coracoglenoid shape was examined and classified into Type I - round bracket, Type II - square bracket and Type III fish hook. Morphometric parameters such as length, breadth, thickness and height, acromiocoracoid and coracoglenoid distance were measured and statistical analysis was carried out.

Results: Type I Coracoglenoid shape was observed in maximum number of specimens. Differences observed in the morphometric parameters observed on right and left side were statistically insignificant.

Clinical Significance: The coracoid is involved in many surgical interventions on the glenohumeral joint, hence variant dimensions of the coracoid process are of importance for Radiologists and Orthopaedic surgeons for planning reparative procedures on the shoulder and is also useful in Forensics for gender determination.

Conclusion: The outcomes of the present study establish the proportions of the coracoid process which can aid in finding the suitable approaches for repair of a coracoid fracture.
