Dysplasia Epiphysealis Hemimelica eMedicine Orthopedics

Description: Dysplasia epiphysealis hemimelica (DEH), or Trevor disease, is a rare developmental disorder affecting the epiphyses in young children. The first report of DEH in the literature was by Mouchet and Belt in 1926, who described the condition as a tarsal bone disorder and used the term tarsomegalie. In 1950, Trevor reviewed 10 cases of DEH and used the term tarsoepiphyseal aclasis. In 1956, Fairbank reported 14 cases and coined the term dysplasia epiphysealis hemimelica. DEH is thought to be a variant of osteochondroma arising within a joint.
