摘要：Introduction: The scapula (shoulder blade) is a triangular flat bone that lies on the posterolateral aspect of thethorax. The scapula bears various angles namely superior, inferior, lateral, medial, acromial and coracoidangle. The three borders meet strategically to form the referenced three angles (lateral, superior, and inferior. Itslateral angle, truncated and broad, bears the glenoid cavity which articulates with the head of the humerus at theglenohumeral joint. The morphology of the glenoid cavity is highly variable. The glenoid rim presents a notch inits upper and front partMaterials and Methods: This study included thorough observation of 120 dry human scapulae, 67 from left sideand 53 from right side, obtained from department of Anatomy, Sri Guru Ram Rai Institute of medical and healthsciences Dehradun following standard guidelines. All the metric and non metric parameters were observed andrecorded in tabulated form.Results: The mean length of scapula of left side was observed as 127.35±12.35 and right side was 128.10±11.21.Thetotal mean value for length of scapula was noted as 130.21±12.65 . The mean breadth of scapula was recordedas 96.98±7.62mm. The mean value of scapular index was listed as 68.47±3.98 . The mean of infraspinous lengthwas recorded as 99.14±9.54 and the infraspinous index was 99.65±8.32.The mean AP glenoid diameter 1 was24.54±2.65mm, the mean AP glenoid diameter 2 was 16.56±2.45mm and the mean AP glenoid diameter 3 was17.09±2.75 The shape of the glenoid cavity was recorded as type 1(oval) 17.50%, Type2 (pear) 48.14%,Type3(inverted coma) and Type4(other).Conclusion: To summarize, the present study provides a base line data of different scapular dimensions on theleft and right sides. Knowledge of the measurements and indices of various parameters of scapula such aslength, width and various parameters of glenoid cavity can be used for comparative anatomy and also fordefining the race.
