Khan Hijab A, Dhamangaokar AC
Introduction: The snapping scapula syndrome is an infrequently described cause of shoulder pain .This syndrome was first described by Boinet in 1867. Milch and Burman described this phenomenon to be secondary to an abnormality between the anterior surface of scapula and the thoracic wall Aims and Objective: To study human scapula concerned with Snapping Scapula Syndrome Methodology: One hundred and one unpaired (56 left and 45 rights sided), complete and undamaged dry human scapulae were obtained from a teaching medical institute of Mumbai. The bones were of unknown age and gender. The parameters measured were recorded in the proforma. The study was conducted after receiving approval from institutional ethics committee. Data was entered in Microsoft Excel 2007 and then transferred to SPSS version 17. Statistical analysis was done using SPSS software version 17 and mean, median, range and standard deviation were calculated. Result: Distance between the inferior surface of acromial process and supraglenoid tubercle was 29.38+/-2.8 mm. Average forward angulation of base of coracoid process at costal surface was141.95+/-8.25 degrees. Superomedial angle of the costal surface was137.93+/-8.85 degrees. Average anteroposterior thickness of superior angle of scapula was 3.28+/-1.06 mm. Anteroposterior thickness of inferior angle of scapula measured in this study ranged from 3.8 mm to 9.5 mm with average of 6.75+/-1.06 mm. Out of 101 studied scapulae, rhinocerous horn was present in 16.83 percent.
