"Madelung deformity was first described in 1878 by Otto Wilhelm Madelung (1846-1926), a German surgeon 4."
"pseudo-Madelung deformity: shows negative ulnar variance"
"trauma: distal radius and ulnar trauma can cause a pseudo-Madelung deformity when the distal radius medial joint fuses with the ulna while the lateral joint space continues to grow; this is seen especially when the physis is still open"
"infection: can cause abnormal fusion of the distal radial and ulnar growth plates, and a pseudo-Madelung deformity occurs when the distal radius medial joint fuses with the ulna while the lateral joint space continues to grow"
"Madelung dyschondrosteosis"
"Hurler mucopolysaccharidosis 1"

"Turner syndrome: other hand findings are osteopenia, metacarpal shortening (especially 4th metacarpal), and decreased carpal angles which resemble Madelung deformities; usually bilateral"
