[Toxopachyosteosis of the tibial and fibular diaphyses (Weismann-Netter and Stuhl syndrome) (author's transl)].

Two cases of toxopachyosteosis involving the tibial and fibular diaphyses are reported. This rare condition, which is usually well tolerated, was first described by Weismann-Netter and Stuhl in 1954. This dysplasia affects both tibias and fibulas and usually results in symmetrical deformations. Characteristic features are anterior bowing of affected bones, with posterior thickening of the cortices. There are few clinical manifestations; small stature, often with delayed onset of walking. Biological investigations are negative. Roentgenograms often show embedding of the last lumbar vertebra with horizontalization of the sacrum. Scoliosis is a common finding.
