Description

The purpose of treatment in Legg-Calvé-Perthes disease is the reduction of the deformity of the capital femoral epiphysis. For this aim, the lower limbs are enclosed from the groins to the toes in a plaster cylinder, and abduction sufficient to introduce the entire epiphysis within the acetabulum and some degree of internal rotation are provided by a wooden bar between the legs. Children in the abduction cast have unrestricted use of the flexion-extension range of hip motion. Weight-bearing is forbidden, but surprising range of activities are rapidly developed and enjoyed. The cases, which were treated in abduction cast for 12 months or more were studied using the measurement technique of Heyman and Herndon.<br>The result are as follows:<br>1. For the cases with sclerosing, flattening and fragmentation, abduction cast was effective, if femoral epiphysis was entirely put within acetabulum.<br>2. For the cases in which healing process had already begun, abduction cast was not effective.<br>3. For the deformity of the femoral neck, not effective.
