Pseudo Madelung Deformity

Pseudo-Madelung deformity refers to increased radial inclination (i.e. ulnar tilt) of the distal radius but with negative ulnar variance and the absence of other typical features of Madelung deformity ¹.

Pathology

Pseudo-Madelung deformity can be due to ^1-3:

hereditary multiple exostoses
post-trauma, e.g. physeal injuries
rickets
enchondromatosis - Ollier disease ¹
post-inflammatory or infectious arthritis
achondroplasia
mucopolysaccharidoses, e.g. Morquio syndrome, Hurler syndrome

Radiographic features

Pseudo-Madelung deformity is differentiated from Madelung deformity by the absence of ⁴:

positive ulnar variance
dorsal subluxation of distal ulna
wedging of carpal bones between the radius and ulna
dorsal and radial bowing of the radius
failure of ossification of ulnar side of the distal radial epiphysis
"V-shaped" proximal carpal row
