Estimation of stature in adult forensic cases with available long bones of the limbs is routine, but such estimation is less common in subadult cases. Long bones from subadult cases are often used to estimate age, but in some instances stature may be helpful or even critical for identification. Few published regression equations exist for consultation in such cases. Data from the longitudinal growth study conducted by the Child Research Council in Denver in the mid-1900s are utilized to produce dual-sex and single-sex regression equations for the six long bones of the limbs (humerus, radius, ulna, femur, tibia, and fibula) and for the combined femur+tibia length. All measurements are from radiographs and are of diaphyseal length. Examples show that similar results can be obtained using a two-step process of "ballpark" estimation from published tables of the Denver data, but these new regressions allow a one-step standard error estimate for the means. Regressions are further compared with those previously published by Finnish researchers, which are generally broadly comparable. More routine stature estimation in subadult cases is encouraged both as an aid to possible identification and as a test of the available regression equations.
利用四肢长骨对成年法医案件中的身高进行估算是常规操作,但在未成年案件中这种估算不太常见。未成年案件中的长骨通常用于估算年龄,但在某些情况下,身高对于身份识别可能会有所帮助甚至至关重要。在这类案件中,可供参考的已发表回归方程很少。利用20世纪中叶丹佛儿童研究委员会进行的纵向生长研究数据,得出了四肢六根长骨(肱骨、桡骨、尺骨、股骨、胫骨和腓骨)以及股骨+胫骨联合长度的两性和单性回归方程。所有测量均来自X光片,且为骨干长度。示例表明,使用丹佛数据已发表表格中的“大致”估算两步法可以获得类似结果,但这些新的回归方程允许对均值进行一步标准误差估计。还将这些回归方程与芬兰研究人员之前发表的方程进行了进一步比较,总体上大致可比。鼓励在未成年案件中更常规地进行身高估算,既有助于可能的身份识别,也可作为对现有回归方程的检验。
