title: [Results of the follow-up of varus osteotomy in Perthes disease with reference to the hip value].
abstract: A total of 89 patients with 105 hip joints affected by Perthes' disease at Catterall's stages II to IV, which had been treated by varus osteotomy, were re-examined clinically and radiologically between two and ten years after surgery. The clinical and subjective results of treatment were generally good. The best clinical and radiologic results were found in patients who contracted the disease before the age of seven and in whom necrosis was not yet at an advanced stage. The results in children who did not undergo treatment until after the age of eight and those with the disease at Catterall's stage IV were significantly poorer as far as arthrotic deformation of the hip joint was concerned. Radiologic evaluation of the hips examined, with regard to severity of arthrosis, epiphyseal index, and hip value show that the hip value is the best means of distinguishing prearthrotically deformed hip joints from normal findings. For example, at the time of follow-up severe prearthrotic changes were found in 40 of 105 hip joints when the hip values were analyzed. Therefore, in cases of Perthes' disease also, the hip value is of special importance in prognostic counseling of patients as regards the extent to which the hip joint can be subjected to stress either at work or in sports.
