Sex determination is the first step in establishing the identity of skeletal remains. Many studies included biometry of posterior features of hip bone. Very few studies are reported involving the biometry of anterior features of the hip bone. Anterior features of hip bone are important especially, if there is damage to the posterior features of hip bone in cases involving deliberate disfigurement of the body to resist identification of the crime in medicolegal cases.
The present study was done to evaluate the effectiveness of anterior border parameters of the hip bone for prediction of sex using discriminant function analysis in South Indian population.
A total of 206 dry bones were used (121 male and 85 female) and parameters like the distance between pubic tubercle and anterior rim of acetabulum, vertical acetabular diameter, transverse acetabular diameter, and the distance between pubic tubercle to highest point on the iliopubic eminence were measured using Vernier calipers. Normally distributed variables were compared using Students t-test to analyse the significance.
There was significant difference between the male and female hip bones of the observed variables with p-value less than 0.05. In parameters like the distance between pubic tubercle to anterior rim of acetabulum and distance between the highest points on iliopubic eminence to pubic tubercle; the values were more in female when compared to males. In parameters like vertical and transverse acetabular diameters; the values in males were more when compared to females.
These parameters of hip bone can be utilised for sex determination in South Indian population.
性别鉴定是确定骨骼遗骸身份的第一步。许多研究包括对髋骨后部特征的生物测量。涉及髋骨前部特征生物测量的研究报道极少。尤其是在法医学案件中，若因故意毁损尸体以抗拒身份识别而导致髋骨后部特征受损，髋骨前部特征就显得尤为重要。
本研究旨在评估在南印度人群中，利用判别函数分析通过髋骨前缘参数预测性别的有效性。
共使用206块干燥骨骼（121块男性骨骼和85块女性骨骼），使用游标卡尺测量耻骨结节与髋臼前缘之间的距离、髋臼垂直直径、髋臼横直径以及耻骨结节至髂耻隆起最高点之间的距离等参数。使用学生t检验比较正态分布变量以分析其显著性。
观察变量的男性和女性髋骨之间存在显著差异，p值小于0.05。在耻骨结节至髋臼前缘的距离以及髂耻隆起最高点至耻骨结节的距离等参数方面，女性的值高于男性。在髋臼垂直直径和髋臼横直径等参数方面，男性的值高于女性。
这些髋骨参数可用于南印度人群的性别鉴定。
