Determination of the sex is one of the most important steps when evaluating decomposed bodies or skeletal remnants. However, relevant data exhibit significant ethnic and temporal variation. This study provides information on in vivo femoral dimensions of Anatolian Caucasians. 50 males and 54 females with ages between 18 and 68 years were investigated with computed tomography. For males, mean maximum length (ML) was 448.2mm, mean vertical head diameter (VHD) was 48.8mm, mean midshaft transverse diameter (MTD) was 26.5mm, and mean anterior bowing (AB) was 759.3mm. For females, these were 419.0mm, 43.4mm, 25.6mm, and 779.5mm, respectively. Femoral dimensions of Anatolian Caucasians were not entirely similar to a single racial group that was already reported. There was a significant difference between males and females regarding ML and VHD (p<0.0001 for both). MTD and AB did not exhibit sexual dysmorphism. Discriminant analysis for sex type produced 83.3% accuracy when ML was used, and 76.9% accuracy when VHD was used (p<0.0001). Combined use of both parameters increased overall accuracy to 84.6% (p<0.0001). For VHD, cut-off value of 44.9mm produced 94% sensitivity and 83% specificity. For ML, cut-off value of 428.6 produced 80% sensitivity and 67% specificity.
在评估腐败尸体或骨骼残骸时,确定性别是最重要的步骤之一。然而,相关数据存在显著的种族和时间差异。本研究提供了安纳托利亚高加索人的活体股骨尺寸信息。对50名年龄在18至68岁之间的男性和54名女性进行了计算机断层扫描研究。男性的平均最大长度(ML)为448.2毫米,平均垂直头径(VHD)为48.8毫米,平均骨干中部横径(MTD)为26.5毫米,平均前弓(AB)为759.3毫米。女性的这些数值分别为419.0毫米、43.4毫米、25.6毫米和779.5毫米。安纳托利亚高加索人的股骨尺寸与已报道的单一种族群体并不完全相似。男性和女性在ML和VHD方面存在显著差异(两者p均<0.0001)。MTD和AB未表现出性别二态性。使用ML进行性别类型判别分析时准确率为83.3%,使用VHD时准确率为76.9%(p<0.0001)。同时使用这两个参数可将总体准确率提高到84.6%(p<0.0001)。对于VHD,截断值为44.9毫米时灵敏度为94%,特异性为83%。对于ML,截断值为428.6时灵敏度为80%,特异性为67%。
