The growth of five variables of the tibia (diaphyseal length, diaphyseal length plus distal epiphysis, condylo-malleolar length, sagittal diameter of the proximal epiphysis, maximum breadth of the distal epiphysis) were analysed using polynomial regression in order to evaluate their significance and capacity for age and sex determination during and after growth. Data were collected from 181 (90♂ and 91♀) individuals ranging from birth to 25 years of age and belonging to three documented collections from Western Europe. Results indicate that all five variables exhibit linear behaviour during growth, which can be expressed by a first-degree polynomial function. Sexual significant differences were observed from age 15 onward in the two epiphysis measurements and condylo-malleolar length, suggesting that these three variables could be useful for sex determination in individuals older than 15 years. Strong correlation coefficients were identified between the five tibial variables and age. These results indicate that any of the studied tibial measurements is likely to serve as a useful source for estimating sub-adult age in both archaeological and forensic samples.
分析了胫骨的五个变量（骨干长度、骨干长度加远端骨骺、踝距长度、近端骨骺矢状径、远端骨骺最大宽度）的生长情况，使用多项式回归来评估它们在生长期间和之后用于年龄和性别鉴定的重要性和能力。数据来自三个来自西欧的有记录的人群，共 181 人（90 名男性和 91 名女性），年龄从出生到 25 岁不等。结果表明，所有五个变量在生长过程中均表现出线性行为，可以用一次多项式函数来表示。从 15 岁开始，在两个骨骺测量值和踝距长度上观察到了性别显著差异，这表明这三个变量可能对 15 岁以上的个体的性别鉴定有用。五个胫骨变量与年龄之间存在很强的相关系数。这些结果表明，在考古和法医样本中，任何一种研究中的胫骨测量都可能成为估计未成年年龄的有用来源。
