We studied 100 hips affected by CDH treated with Pavlic harness, and evaluated the relations between the rate of successful reduction and the severity of dislocation, and between the occurrence of avascular necrosis and the severity of dislocation. The severity of 21 hips which were unable to be reduced was higher than that of 79 hips which were successfully reduced. Among the successfully reduced hips, the "Distance a", as defined by Yamamuro, of 11 hips which later developed avascular necrosis were statistically smaller than that of 68 hips which did not develop avascular necrosis. "Distance a" of 7mm or less is one of the factors causing avascular necrosis when treated with the Pavlic harness. In cases with this risk factor, it may, therefore, be better to select a method other than the Pavlic harness for initial treatment of CDH.
