Anatomical variations in scapula: A study with correlation to gender and sides

Introduction: Anatomical variation is defined as the normal flexibility in the topography and morphology of body structures. The present study was planned to study anatomical variations in dry scapula of North Indian population and their comparison between males and females on both sides. Material and Methods: The study was performed at the Department of Anatomy, PGIMS, Rohtak, on fifty pairs of human scapulae, out of which thirty were males and twenty were females. Various anatomical variations were noted such as sulcus for circumflex scapular artery, costal facets, horizontal inferior border, scapular foramina, and facet on inferior surface of acromion process. Morphological types of tip of acromion process, inferior surface of acromion process, and superior border of scapula were studied. These parameters were compared in both sexes on both the sides. Results: Majority of the anatomical variations were common in females in comparison to males. Discussion and Conclusion: Knowledge of the anatomical variations of scapula is the key to a successful outcome in the clinical setting.
