To compare the predictive value of the Herring lateral pillar and the Catterall classifications of Legg-Calve-Perthes' disease, 71 hips with radiographic followup to maturity were reviewed. The Herring classification was a significantly better predictor of Stulberg outcome than the Catterall classification. Three independent observers classified early fragmentation stage films by both Herring and Catterall classifications. The interobserver reliability of the Herring classificaiton was significantly better than the reliability of the Catterall measure.
