Background: The shoulder joint is vulnerable for dislocation due to disproportionate articular surfaces. The morphology of shoulder bones is well investigated in the western population, whether Glenoid conforms to the same dimensions in Indian population is sparsely known. The knowledge of bony morphometry, their variation and racial differences are of paramount significance in the diagnosis and management of shoulder diseases and to produce a more anatomical result in shoulder replacement surgery. Aim: The current investigation was aimed to study and analyze morphometric data of Glenoid in Indian population. Materials and Methods: We studied sixty seven wet scapulae of known sex, retrieved from embalmed human cadavers age varied from sixty to eighty years. The Glenoid parameters under consideration were height, breadth and version. The data obtained was analysed and discussed with other osteological studies. Results: The mean combined glenoid height recorded was 34.07±3.79mm and the average combined anteriorposterior diameter of the lower half of glenoid was 24.44 ±2.98 mm .The values of glenoid version showed wide distribution in our study ranging from-10 0 to +6 0 The mean glenoid version of the left side-1.00±4.06 0 and on the right side-3.30±3.63 0 Conclusion: The glenoid version showed a wide variation ranging from (-10 0 to +6 0) on comparison, the right shoulders were found to be more retroverted than the left. The glenoid height and width noted was in accordance with other Indian studies. However significant variation with respect to western bone morphology has emerged.

Introduction: It is know that Asian shoulders are small and require attention while planning replacement surgeries. The prostheses currently available are based on western database and only few sizes fit into the Asian shoulders. The native database will also help us to calculate humerus bone loss and prostheses designing.
