Early diagnosis and treatment are necessary to prevent joint dysfunction and deformity and may be surgical or non-surgical depending on the location and the symptoms. Due to the progressive nature of this disorder and the chance of worsening deformity, patients should be followed until skeletal maturity. The cause of dysplasia epiphysealis hemimelica is not known.
