Dysplasia epiphysealis hemimelica with involvement of the distal tibial epiphysis and talus: recurrence of a case and literature review

Abstract

Dysplasia epiphysealis hemimelica is a rare developmental disorder with unknown etiology affecting epiphysis mostly in childhood. Dysplasia epiphysealis hemimelica is usually considered an intra-articular variant of an osteochondroma owing to its presenting symptoms and histologic findings. Surgical treatment is mandatory when symptoms such as pain, joint impingement, or deformity are present and will yield good results when the mass is juxta-articular or extra-articular. In those cases in which the mass is intra-articular and surgical intervention could affect the growth of the epiphysis, surgical treatment should be carefully evaluated and considered. A case of recurrence of dysplasia epiphysealis hemimelica located in the distal tibial epiphysis and talus that was successfully treated with surgery is presented.
