Normally the upper border of the proximal fibular epiphysis is in line with the upper tibial growth plate--well inferior to the joint horizontal orientation line; whereas Blount's disease, congenital longitudinal deficiency of the tibia, and achondroplasia demonstrate relative overgrowth of the fibula, and the fibular epiphysis is more proximal, near the joint line [21].

The diagnosis of Blount's disease is based on several radiographic changes in the proximal tibia best visualized with standing anteroposterior images of both legs.
