The hip bone is considered to be one of the most reliable indicators in sex determination. The aim of this study was to test the reliability of the DSP method for the hip bone proposed by Murail et al. (Bull Mem Soc Anthropol Paris, 17, 2005, 167) on a sample from a present-day population in France (52 males and 54 females). Ten linear measurements were collected from three-dimensional models derived from computed tomography images (CTI). To quantify the proportions of correct sex determinations, a more rigorous posterior probability threshold of 0.95 was applied. Using all 10 measurements, 92.3% of males and 97.2% of females were sexed correctly. The percentage of undetermined specimens varied depending on the used combination of measurements; however, all sexes were assigned with a 100% accuracy. This study proves that DSP is an appropriate and reliable tool for sex determination, based on dimensions obtained from CTI.
髋骨被认为是性别判定中最可靠的指标之一。本研究的目的是在法国现代人群样本（52名男性和54名女性）上测试Murail等人（《巴黎人类学会公报》，17，2005，167）提出的髋骨DSP方法的可靠性。从计算机断层扫描图像（CTI）衍生的三维模型中收集了10项线性测量数据。为了量化正确性别判定的比例，应用了更严格的0.95后验概率阈值。使用全部10项测量数据时，92.3%的男性和97.2%的女性性别判定正确。未确定标本的百分比因所使用的测量组合而异；然而，所有性别的判定准确率均为100%。本研究证明，基于从CTI获得的尺寸，DSP是一种用于性别判定的合适且可靠的工具。
