|Evaluation of morphological variation in shape and size of scapulae|
Background: The scapulae are a pair of triangular, large, flat bones that are situated dorsally in the ribcage in relation with the second to seventh ribs. The present study was conducted to evaluate scapulae of both genders. Materials & Methods: The present study was conducted on 50 scapuale bones of both gender. We classified scapula into three types; pear shaped or inverted comma shape in presence of a glenoid notch & oval in absence of notch. We calculated Superior-Inferior Glenoid Diameter (SI), Anterior-Posterior Glenoid Diameter-1 (AP-1), Anterior-Posterior Glenoid Diameter-2 (AP-2) and Glenoid cavity index (GCI). Results: Pear type was present in 25, inverted comma in 15 and oval in 10 scapulae. The difference was significant (P< 0.05). The mean length on left side was 134.6 mm and on right side was 136.2 mm, width was 97.5 mm and 98.4 mm on both sides, superior-inferior glenoid diameter was 35.7 mm and 36.3 mm on both sides, anterior-posterior glenoid diameter-1 was 24.6 mm and 23.2 mm in both sides, anterior-posterior glenoid diameter-2 was 16.7 mm and 17.2 mm in both sides and glenoid cavity index was 65.4 mm and 66.2 mm in both sides. The difference was significant (P< 0.05). Conclusion: Authors suggested that common type of scapula was pear type followed by inverted comma and oval shaped.
