The distinctive morphology of the human innominate bone (os coxae) and its clear sexual dimorphism make it of interest from anatomical, anthropological and forensic points of view. The features of the greater sciatic notch of the coxae are characteristic and are commonly used to determine sex in unknown individuals. In this study, several measurements of the greater sciatic notch, e.g. width (AB), depth (OC) and width of the posterior segment (OB) were taken and indices I and II were calculated in 64 adult (32 men and 32 women) and side (right: left) coxae radiography (A-P view). Results indicated that out of all the parameters studied, width of the notch (right and left) (P < 0.001), posterior segment width (right and left) (P < 0.001), right (P = 0.036) and left (P = 0.008) index II of notch were found to be significantly greater in women as compared with men. Discriminant function analysis showed that the accuracy of sex determination varied from 100% in the men and 40% in the women groups to 70% for the total group. These results can be used as an aid to the identification of human skeletal remains in Iranian people.
人类无名骨（髋骨）独特的形态及其明显的性别二态性，从解剖学、人类学和法医学角度来看都颇受关注。髋骨坐骨大切迹的特征很典型，常用于判定身份不明个体的性别。在本研究中，对64例成人（32名男性和32名女性）髋骨的X线前后位片测量了坐骨大切迹的多项指标，如宽度（AB）、深度（OC）和后段宽度（OB），并计算了指数I和指数II。结果表明，在所研究的所有参数中，切迹宽度（左右）（P < 0.001）、后段宽度（左右）（P < 0.001）、切迹右侧（P = 0.036）和左侧（P = 0.008）的指数II在女性中显著大于男性。判别函数分析表明，性别判定的准确率在男性组为100%，女性组为40%，总体为70%。这些结果可用于辅助识别伊朗人群中的人类骨骼遗骸。
