Background: The scapula is a large, flat, triangular bone lying posterolaterally on the chest wall, overlying second to seventh ribs. The variations of shape and size of glenoid cavity of scapula is of importance in understanding the rotator cuff disease, shoulder dislocation and to decide the proper size of the glenoid component in the shoulder arthroplasty.

Aims and objectives: Present study aims to determine various anthropometric parameters of glenoid cavity including the variations of its shape.

Materials and Methods: A total of 106 (Rt -52, Lt – 54) dry scapulae available in the Department of Anatomy of Calcutta National Medical College, kolkata and N R S Medical College, Kolkata were taken for the study. The glenoid fossa were measured in supero-inferior(SI) diameter, and antero-posterior diameter at three places from upper to lower direction (AP1,AP2,AP3), The depth of Glenoid (Gd): The depth of glenoid was measured by filling the glenoid fossa with modelling dough, and keeping it on to a plane surface to make the outer surface plane and at the middle of this mould the highest thickness was measured. The measurements are taken via spreading slide calipers in milimeters. For observing the shape the edge of glenoid fossa were highlighted with coloured chalk.

Results: Both sided scapulae were analysed separately for shape and their morphometric analysis done. Pear and comma shaped glenoid were of equal number in right side and pear shape were predominant in left side. both sided oval shape were least common. Mean values for SI were 35.065+3.59mm (Right side) and 34.149+3.50mm(Left side). Mean values for AP1 were 15.34+1.67mm (Right side) and 15.29+1.96mm (Left side). Mean values for AP2 were 22.08+3.56mm (Right side) and 21.47+3.17mm (Left side). Mean values for AP3 were 23.46+3.21mm (Right side) and 23.46+3.21mm (Left side). Mean values for depth of glenoid (Gd)3.54+0.73mm (Right side) and 3.692+0.62mm(Left side). No statistically significant difference in findings recorded between the right and left side.

Conclusion: This study   will contribute some relevant data and help the orthopaeditians in dealing with cases of shoulder pathology and shoulder arthroplasty cases.
