English⧼Colon⧽ F6: (a, b) AP radiographs of a-7 and 10 year old boys with hypochondroplasia with variable degrees of genu varum. Long bones areshort, with wide-appearing diaphysis, mild flaring of epiphyseal-metaphyseal junction. Elongated distal fibulae, short and broad femoralneck and rectangular proximal tibial epiphyses were apparent. There was an increased distal femoral and an increased proximal tibia varus,whereas the distal tibia is almost normally configured. In contrast to achondroplasia the femoral condyle and tibial plateau is much lesswidened and flared.
