Shape and dimensions of the glenoid cavity are important in the design and fitting of glenoid components for total shoulder arthroplasty. An understanding of variations in normal anatomy of the glenoid is essential while evaluating pathological conditions like osseous bankart lesions and osteochondral defects. In the present study done on 224 dry scapulae, three glenoid diameters were measured. The average superiorinferior diameter on right and the left side were 33.68±4.32mm and 32.09±4.11mm respectively. The average anteriorposterior diameter of the lower half of the right glenoid was 23.29±2.34mm and that of the left glenoid was 24.90±2,95mm. the mean diameter of the upper half of the right glenoid was 15.74±1.75mm and that of the left glenoid was 16.81±1.74mm. The left glenoid cavity was slightly shorter in length, but broader especially in the upper part as compared to the left glenoid cavity. The current study also recorded a higher percentage of glenoid cavities having the glenoid notch in the anterior margin of the glenoid as compared to earlier studies. While evaluating defects and lesions of the glenoid, this fact could be useful. Smaller dimensions of the glenoid cavities in the south Indian population may have to be taken into consideration while designing and fitting glenoid components while performing total shoulder arthroplasty.
