Madelung's deformity

named after the German surgeon Otto Wilhelm Madelung (1846-1926)
German: Madelung-Deformität

Madelung´s deformity is a deformity of the cubital joint, bent to the volar side. It is caused by reduced growth of the distal radial epiphysis with a missmatch to the relatively longer healthy grown ulna. Usually it appears symmetrically on both distal upper limbs. It is not related to Madelung´s Disease.
