|Patient: 12 year 6 month old male|
|History: 12 year old male with ankle pain.|
|Findings: There is a fixation screw in the distal tibia. There is osteochondroma formation with ankle fusion. There is leg length discrepancy (right greter than left) of approximatley 3.8cm.|
|Diagnosis: Trevor's Disease or Dysplasia Epiphysealis Hemimelica|
|Discussion: Dysplasia epiphysealis hemimelica (DEH) or Trevor's disease is a rare developmental disorder affecting the epiphyses in young children. |
Microscopically: The histologic appearance of the lesion is that of a well-defined cartilage cap over projecting bone that is contiguous with the underlying normal bone. It is indistinguishable from that of an osteochondroma.
Frequency: The incidence of DEH has been estimated at 1 case per million population.
DEH most commonly occurs around the knee, talus, and tarsal navicular and first cuneiform joints.
Complications include recurrence of the angular deformity after the corrective osteotomy, degenerative osteoarthritis, fixed deformity, leg-length discrepancy, and loose bodies.
