General Discussion

Dysplasia epiphysealis hemimelica, also known as Trevor disease, is a rare skeletal developmental disorder of childhood. It is characterized by an overgrowth of cartilage on the ends (epiphyses) of the long bones of the arms and legs and the bones of the wrists (carpal bones) or the ankle (tarsal bones). The disorder may involve one epiphysis (localized) or multiple epiphyses. Most affected individuals develop a painless mass or swelling around the affected joint. Additional symptoms may develop in some cases. The exact cause of dysplasia epiphysealis hemimelica is unknown.
