Weismann-Netter–Stuhl syndrome, also known as Weismann-Netter syndrome or tibioperoneal diaphyseal toxopachyosteosis, is a rare disorder characterized by bowing of the lower legs and an abnormal thickening of thinner bone in the leg.The main sign is anterior bowing and posterior cortical thickening of the diaphyses of both the tibiae and fibulae. It is thought to be inherited in an autosomal dominant fashion and is most often bilateral and symmetric in nature. [Source: Wikipedia
