Leri Weill Dyschondrosteosis

Leri Weill Dyschondrosteosis is a type of dysplasia associated with Madelung deformity. It is a form of mesomelic dwarfism and was first described by Leri and Weill in 1929. Leri Weill dyschondrosteosis is characterized by

• Variable short stature
• Short forearms,
• Tibial/fibular shortening.

The height of these patients is usually is less than 25th percentile. The features become more  pronounced clinically during adolescence.

No other abnormalities are commonly associated.

Forearm shortening is  bilateral and appears almost identical to that in primary MD. One of the differentiating features is that  that the proximal radius is involved in patients with Leri Weill dyschondrosteosis whereas it is  not involved in primary Madelung deformity.

Both dyschondrosteosis and Madelung deformity are transmitted in an autosomal dominant fashion and the diseases are more predominant in  females.

This condition needs to differentiated in bilateral Madelung deformity. Many children with unilateral and bilateral Madelung deformity have normal stature and no other characteristic of dyschondrosteosis.

It apears that while they may be related but are separate entities.  In primary Madelung deformity without Leri Weill dyschondrosteosis the height of the child is above the 25th percentile in height and there would be no family  history of dyschondrosteosis.

A patient who is less than 5 feet tall at skeletal maturity with involvement of the proximal radius with relatively short tibia and fibula is likely to have Leri Weill dyschondrosteosis.
