Introduction: The shoulder joint of the human body is one of the most important joints. The glenoid cavity of the scapula plays a major role in the formation of the joint, as it has got variable morphology. Anatomical variations of glenoid cavity are also important for understanding the various pathologies involving the shoulder joints. The present study tries to determine the measurements of various dimensions of the glenoid cavity including the variations of its shape and surface area. Materials and methods: The study was carried out on 53 dry, unpaired adult human scapulae of unknown sex in the Department of Anatomy, Sikkim Manipal Institute of Medical Sciences, Gangtok. Out of which, 21 belong to right side and 32 of left side. Results: The mean superior-inferior diameter of the glenoid cavity was observed, in this study as 34.12 ± 3.16mm. The mean Anterior Posterior-1 and Anterior Posterior-2 were 23.28 ± 2.99 mm and 18.04 ± 2.57 mm respectively. The mean surface area of the glenoid cavity was observed as 5.56 ± 1.33mm Conclusion: The diameters of the glenoid cavity observed in this present study were almost similar to those recorded in other studies by various authors except for the shapes. An explanation of this finding may be the numbers of the specimens were less. Since the present study was carried out in limited number of specimens, so further cadaveric or radiological studies are required.
