The presence and size of the epiphyseal centres in the lower limb were studied by post-natal radiological examination in 176 Nigerian newborn infants. The gestational age range was between 27 and 42 weeks. There was no difference between the sexes and between the two halves of the body. There was also no difference in size and pattern of appearance of epiphyseal centres between our infants and their Caucasian counterparts. There was a narrow limit within which the knee epiphyseal centres were visible--the distal femoral at 36 weeks and proximal tibial at 38 weeks. The calcaneus and talus centres were visible in all infants. The prediction interval for estimation of age from the mean size of femoral epiphysis in this material was +/- 32.4 days and +/- 38 days for the tibial epiphysis.
通过对176名尼日利亚新生儿进行出生后放射学检查，研究了下肢骨骺中心的存在情况和大小。胎龄范围在27至42周之间。男女之间以及身体的两半之间没有差异。我们的婴儿与白人婴儿在骨骺中心的大小和出现模式上也没有差异。膝关节骨骺中心可见的范围很窄——股骨远端在36周时可见，胫骨近端在38周时可见。所有婴儿的跟骨和距骨中心均可见。根据该材料中股骨骨骺平均大小估计年龄的预测区间为±32.4天，胫骨骨骺为±38天。
