The distinctive morphology and sexual dimorphism of the human hip bone makes it of interest from the anatomical, anthropological and forensic points of view. The shape of the greater sciatic notch has attracted great attention in the past. In the current investigation, an attempt has been made to find the baseline data of various parameters pertaining to the greater sciatic notch of 100 hip bones of known sex (male:female = 80:20) and side (right:left = 50:50), obtained from the Department of Anatomy, Government Medical College, Amritsar, Punjab, India, during the period 2007-2009. Seven parameters of the notch, viz. width, depth, posterior segment width, total angle, posterior segment angle, index I and index II of the greater sciatic notch were studied. The results thus obtained were compiled, tabulated, statistically analysed and were compared with the accessible literature. Out of all the parameters studied, width of the notch, posterior segment width, total angle, posterior segment angle and index II of notch were found to be significantly greater in women as compared with men. Thus the greater sciatic notch can serve as a reliable sex indicator even when the complete hip bone has not been well preserved.
人类髋骨独特的形态和两性差异使其在解剖学、人类学和法医学方面备受关注。坐骨大切迹的形状在过去就引起了极大关注。在本次研究中，试图获取2007年至2009年期间从印度旁遮普邦阿姆利则政府医学院解剖学系获得的100块已知性别（男:女 = 80:20）和侧别（右:左 = 50:50）的髋骨中与坐骨大切迹相关的各种参数的基线数据。研究了该切迹的七个参数，即宽度、深度、后段宽度、总角度、后段角度、坐骨大切迹指数I和指数II。将所得结果进行整理、列表、统计分析，并与现有文献进行比较。在所有研究的参数中，发现女性的切迹宽度、后段宽度、总角度、后段角度和切迹指数II均显著大于男性。因此，即使完整的髋骨保存不佳，坐骨大切迹也可作为可靠的性别指标。
