Abstract

Background: Scapula is the important flat bone which plays important role in movement of shoulder girdle. Scapular index can be used in comparative anatomy and manufacturing prosthetic products. Present study was carried out with objective to determine the scapular index. Methods: Fifty adult scapula were collected from Department of Anatomy, Chitwan Medical College for study. Gender and ethnicity of scapula were undefined. Bony landmarks are well located. Scapular breadths and lengths were measured using digital vernier caliper. Scapular index was calculated. Statistical analyses were done using SPSS 16 software. Results: Among the fifty scapulae, 52% contributes right sided scapula and 48% left sided scapula. Mean and standard deviation for scapular breadth were 95.84 mm and 3.843 mm respectively. Maximum number (48%) of scapula was found in the range of 90-< 95 mm breadth followed by 95-<100 mm (19%) and 100-<105 mm (14%). Mean and standard deviation for scapular length was 129.28 mm and 11.83 mm respectively. Maximum (22%) of scapula was found in range of 120-<125 mm followed by 125-<135 mm (18%) and 135-150mm (5%). Mean and standard deviation for scapular index were 75.32 mm and& 7.32 mm respectively. Maximum value (46%) of scapular index was found in the range of 70-<75% followed by 65-<70% (16%); 80-85% (14%); 90-<95% (10%); 60-65% (4%) and 85-90% (2%). Conclusions: Scapular breadth, length and indices like scapular index can be used in comparative anatomy and manufacturing prosthetic products and procedure like prosthesis positioning.

人肩胛骨指数的测定

背景:肩胛骨是重要的扁平骨，在肩带运动中起着重要作用。肩胛骨指数可用于比较解剖学和制造假体产品。本研究的目的是确定肩胛骨指数。方法:从奇旺医学院解剖学系收集成人肩胛骨50例进行研究。肩胛骨性别和种族未明确。骨标记定位良好。使用数字游标卡尺测量肩胛骨宽度和长度。计算肩胛骨指数。采用SPSS 16软件进行统计学分析。结果:50块肩胛骨中，右侧肩胛骨占52%，左侧肩胛骨占48%。肩胛骨宽度的平均值为95.84 mm，标准差为3.843 mm。肩胛骨宽度在90 ~ < 95 mm范围内最多(48%)，其次是95 ~ <100 mm(19%)和100 ~ <105 mm(14%)。肩胛骨长度的平均值和标准差分别为129.28 mm和11.83 mm。肩胛骨在120 ~ <125 mm范围内最大(22%)，其次是125 ~ <135 mm(18%)和135 ~ 150mm(5%)。肩胛骨指数的平均值为75.32 mm，标准差为7.32 mm。肩胛骨指数的最大值在70 ~ <75%之间(46%)，其次是65 ~ <70% (16%);80 - 85% (14%);90 - < 95% (10%);60-65%(4%)和85-90%(2%)。结论:肩胛骨宽度、长度及肩胛骨指数等指标可用于比较解剖学、假体产品制造及假体定位等手术。
