Radiology · Musculoskeletal imaging: Madelung deformity

Sample item

An adolescent girl has wrist pain and a prominent distal ulna. A radiograph shows a short radius with volar and ulnar tilt of the distal radial articular surface and a V-shaped carpal row. What is the diagnosis?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

D. Madelung deformity

Madelung deformity is premature closure of the volar-ulnar part of the distal radial physis, causing radial shortening, the tilted articular surface and ulnar prominence. It may be part of Leri-Weill dyschondrosteosis from SHOX deficiency. Radial club hand is radial aplasia, and Kienbock is avascular necrosis of the lunate.

Option by option

  • A. Galeazzi fracture-dislocation

    A Galeazzi injury is a radial shaft fracture with distal radioulnar dislocation.

  • B. Radial club hand

    Radial club hand is absence or hypoplasia of the radius with radial deviation.

  • C. Kienbock disease

    Kienbock disease is lunate collapse and sclerosis.

  • D. Madelung deformity (correct)

    Correct. Volar-ulnar tilt of a short radius with a V-shaped carpus is Madelung deformity.
