title: A prospective study of children with untreated Catterall group 1 Perthes' disease.
abstract: Twenty-four hips in twenty children affected by Group 1 Perthes' disease have been reviewed to assess the radiographic result after a minimum follow-up of four years. The children were allocated to Group 1 prospectively after examination of the early radiographs and no specific treatment of the affected hip was provided. The radiographic end results assessed by three methods were good even in those cases in which the additional stress of containment splintage of the contralateral hip was applied.
