Stature is an important component of the biological profile of unknown skeletal remains and regression equations for estimating stature have been derived for a number of bones. However, bones are rarely recovered intact in both forensic and archaeological cases, and regression formulae for fragmentary remains have therefore been developed. These equations are, however, both sex- and population-specific, and while formulae exist for many populations, those using fragmentary tibiae do not exist for black South Africans. The aim of this study was therefore to establish regression equations for estimating total skeletal height (TSH), and thereby stature, from tibial fragments in a black South African population. A sample of 99 male and 99 female black South African skeletons were obtained from the Raymond A. Dart Collection of Human Skeletons and the TSH of each skeleton was calculated using the anatomical method. Eleven additional measurements representing tibial fragments were taken on each tibia, and both uni- and multivariate equations were established for estimating TSH from these fragments. All tibial variables were significantly, positively correlated with TSH, and equation correlations ranged between 0.41 and 0.91. The range of standard errors of estimate for the derived sex-specific (3.43-5.06 cm) and sex-pooled (3.44-5.94 cm) multivariate equations were slightly larger than those reported for intact tibiae in black (2.78-3.06 cm) and white (2.59-3.16 cm) South Africans. All uni- and multivariate-equations estimated TSH with moderate to high accuracy, which indicates that in the absence of intact tibiae, the equations presented in this study can be used to give accurate estimates of TSH, and thereby stature, for black South Africans.
身高是未知骨骼遗骸生物特征的重要组成部分，已经针对许多骨骼推导出了估算身高的回归方程。然而，在法医和考古案例中，骨骼很少能完整 recovered intact 。因此，已经开发了针对残缺遗骸的回归公式。然而，这些方程具有性别和人群特异性，虽然存在针对许多人群的公式，但针对南非黑人使用胫骨碎片的公式却不存在。因此，本研究的目的是建立从南非黑人人群的胫骨碎片估算总骨骼高度（TSH）进而估算身高的回归方程。从雷蒙德·A·达特人类骨骼收藏中获取了99具男性和99具女性南非黑人骨骼样本，并使用解剖学方法计算了每具骨骼的TSH。在每根胫骨上额外进行了11项代表胫骨碎片的测量，并建立了单变量和多变量方程，用于从这些碎片估算TSH。所有胫骨变量与TSH均呈显著正相关，方程相关性在0.41至0.91之间。推导的性别特异性（3.43 - 5.06厘米）和性别合并（3.44 - 5.94厘米）多变量方程的估计标准误差范围略大于南非黑人（2.78 - 3.06厘米）和白人（2.59 - 3.16厘米）完整胫骨报告的范围。所有单变量和多变量方程估算TSH的准确性为中等至高，这表明在没有完整胫骨的情况下，本研究中提出的方程可用于准确估算南非黑人的TSH，进而估算身高。
