We compared the prognostic value of the Catterall grouping, the Salter-Thompson grading, the arthrographic shape of the femoral head, and the Herring lateral pillar grouping during the fragmentation stage of @entity2444 in 73 @entity1 with 81 affected @entity572 . Radiographs were available for study from the onset of the disease until skeletal maturity. We used the Stulberg classification to assess outcome. The Herring grade and arthrographic sphericity proved to be the best predictors of final outcome. Combining these two values further increased the predictive value. All but one @entity1 in Herring group A achieved an excellent outcome. In Herring group B, the age of the @entity1 and the sphericity of the femoral head influenced the end result. If the @entity1 was less than seven years old at the onset of symptoms the prognosis was invariably good and all spherical @entity572 in group B had a good outcome with Stulberg grades 1 or 2. Moderately and severely deformed @entity572 on arthrography resulted in Stulberg 3 and 4 @entity572 . None of the @entity572 in Herring group C had a normal appearance at maturity and the outcome was not significantly influenced by the age at onset or the arthrographic appearance.
