An analysis has been made of some of the most obvious variable features in a group of patients with Legg-Calvé-Perthes disease, all seen early and treated similarly. This study was initiated with the thought that perhaps the variations in this disease are not so great as they were once thought to be, especially in groups of patients that are better standardized than those in previous studies. In the cases studied it was found that wide variations did exist, and an attempt was made to correlate these variables. However, the only strong correlation found was between the amount of involvement of the capital epiphysis and the length of the disease process. Analysis of other relationships of various features of the disease suggested some, but not a strong, correlation between any of them. It would seem that further investigation of a larger group of patients might give more definite results.
