Dysplasia epiphysealis hemimelica of the ulna.
A 3-year-old boy developed an abnormality of the forearm and wrist characterized by asymmetrical overgrowth, premature ossification of the distal ulnar epiphysis, shortening of both bones of the forearm, dorsal bowing of the ulna and formation of an enlarged lunate from 2 ossification centers. The eccentric overgrowth of the distal ulnar epiphysis was similar to the abnormality seen in dysplasia epiphysealis hemimelica of the long bones of the lower limbs, tarsal and carpal bones.
