Hip dysplasia associated with Charcot-Marie-Tooth disease in the older child and adolescent

Abstract

Severe hip dysplasia in children with Charcot-Marie-Tooth disease is asymptomatic or minimally symptomatic and usually goes undetected until early adolescence. We report five patients between the ages of 8 and 15 years who presented with hip dysplasia; all five required surgery. The dysplasia in two of these patients was detected only on routine screening because of their older sisters' problems. A multicenter study will be needed to determine the exact incidence of hip dysplasia associated with Charcot-Marie-Tooth disease.
