The lengths of the femur and tibia were measured in lower limb radiographs of 159 newborn infants whose gestational age were determined by both maternal history and a Dubowitz examination. There are strong linear relationships between lengths of tibia and femur with gestational age and birth weight. The correlation coefficients between femoral and tibial lengths and gestational age were respectively 0.97 and 0.94. There is no significant difference in length of the lower limb bones between the sexes.
在159名新生儿的下肢X光片中测量了股骨和胫骨的长度，这些新生儿的孕周通过产妇病史和杜波维茨检查来确定。胫骨和股骨的长度与孕周及出生体重之间存在很强的线性关系。股骨长度和胫骨长度与孕周的相关系数分别为0.97和0.94。两性下肢骨骼的长度没有显著差异。
