Meyer's dysplasia strongly mimics Legg-CalvePerthes' disease despite differing markedly in eventual outcome. This study presents the clinicoradiological features which differentiate it from Perthes' disease in a group of 178 children with a preliminary diagnosis of Perthes' disease, of whom nine were subsequently diagnosed with Meyer's dysplasia. All had a near normal development of the femoral head ; mild flattening was seen in two cases. Clinical initial presentation often resembles Perthes' disease. However, the presence of a granular aspect of the femoral head, often bilateral, in a male child with a preliminary diagnosis of Perthes' disease should alert the clinician to the possibility of Meyer's dysplasia. Restitution of normal capital architecture is usual ; there may however be a mild residual hypoplasia.
