Summary: A radiological study was made of the lower limb ossification centres in a group of 153 normal newborn infants. Their gestational ages ranged from 37 to 44 weeks. The lower femoral centre was present in 98% of all cases. The upper tibial centre was found in 73.1% of cases over 38 weeks of gestation. The cuboid centre was shown in 37.6% of those over 40 weeks. No correlation between sex and the ossification of the lower limb centres was found. No significant differences in the incidence of the lower femoral and cuboid centres in the 3 ethnic groups were noted. However, the upper tibial centre was present significantly more often in Indian infants than in Chinese or Malay infants. The higher the birth‐weight, the more likely were the upper tibial and cuboid centres to be seen radiologically.
