The bipedal gait and consequential freedom of the upper limb in human beings has made the movements of the shoulder joint a subject of extensive investigations. The scapular angles provide the base and leverage to various muscles and have been correlated with the different movements of the shoulder joint.
In the present study, different angles of scapula namely superior, inferior, lateral, medial, acromial and coracoid angles were measured in the North Indian population. The study was conducted on 100 scapulas (R:L=50:50) obtained from Department of Anatomy, Government Medical College, Amritsar. For measuring the angles, centimetre scales and protractor were used.
The mean value of superior angle was observed to be 100.830 (R=100.320 : L=101.340); inferior angle was 63.620 (R=68.10:L=59.140); lateral angle was 61.720 (R=65.90 : L=57.540); medial angle was 147.640 (R=151.320 : L=143.960); acromial angle was 106.470 (R=107.680 : L=105.260) and coracoid angle was 83.30 (R=84.240:L=82.020).
It was observed that all angles were higher in the right sided bones except superior angle. Also a wide range was seen in all the angles.
人类的双足步态以及随之而来的上肢活动自由，使得肩关节的运动成为广泛研究的课题。肩胛角为各种肌肉提供了基础和杠杆作用，并与肩关节的不同运动相关。
在本研究中，对北印度人群的肩胛骨不同角度进行了测量，即上角、下角、外侧角、内侧角、肩峰角和喙突角。研究使用了从阿姆利则政府医学院解剖学系获得的100块肩胛骨（右：左 = 50：50）。使用厘米尺和量角器测量角度。
观察到上角的平均值为100.83°（右侧 = 100.32°：左侧 = 101.34°）；下角为63.62°（右侧 = 68.1°：左侧 = 59.14°）；外侧角为61.72°（右侧 = 65.9°：左侧 = 57.54°）；内侧角为147.64°（右侧 = 151.32°：左侧 = 143.96°）；肩峰角为106.47°（右侧 = 107.68°：左侧 = 105.26°）；喙突角为83.3°（右侧 = 84.24°：左侧 = 82.02°）。
观察到除上角外，右侧骨骼的所有角度均更高。所有角度也都有较宽的范围。
