Incidence of full containment of the femoral head after Legg-Calvé-Perthes disease and in the "normal" hip

Abstract

Forty-eight children with unilateral Legg-Calvé-Perthes disease were studied to determine the extent of femoral head containment present after treatment. Only 0-4% of the hips treated with bed rest and 10-35% of the contralateral hips were fully contained. The criterion of full containment for a good result is, therefore, not valid.
