Genu valgum after proximal tibial fractures in children.

Eight children with fractures of the proximal tibial metaphysis developed a significant genu valgum on the injured side. A study of the radiographs showed that the deformity was primarily due to bowing of the tibia below the site of fracture. The deformity may be the result of plastic bowing of the tibia accentuated by weight bearing during healing.
