7. What is Madelung deformity?

Madelung deformity is characterized by shortening and bowing of the radius

with dorsal subluxation of distal ulna. The deformity usually becomes clini-

cally evident by adolescence. The causes include SHOX-insufficiency-related

disorders, mucopolysaccharoidosis, achondroplasia, trauma, or idiopathic in

origin.
