Madelung Deformity

General Considerations

  • Arrest of epiphyseal growth of the ulnar (medial) and volar (anterior) portions of the distal radius
  • Leads to shortening of the radius and relative overgrowth of the ulna
  • Inherited as an autosomal dominant due to mutation on X chromosome and has variable penetrance
  • Overwhelmingly occurs in females
  • Rare congenital deformity that does not usually manifest until 10-14 years
  • May also be seen as an acquired consequence of trauma to the growth plate (e.g. Salter V fracture)
