= LÉRI-LAYANI-WEILL SYNDROME

= mesomelic long-bone shortening (forearm + leg); autosomal dominant; M÷F = 1÷4

• limited motion of elbow + wrist
• bilateral Madelung deformity:
  • radial shortening in relation to ulna
  • bowing of radius laterally + dorsally
  • dorsal subluxation of distal end of ulna
  • carpal wedging between radius + ulna ← triangular shape of distal radial epiphysis + underdevelopment of ulna

DDx: pseudo-Madelung deformity (from trauma / infection)
