title: Long term results of uncemented Judet hip endoprostheses.
abstract: We reviewed 94 patients in whom 113 Judet uncemented total hip endoprostheses had been inserted; 83 had a mean follow up of 10.8 years (range 6 to 13 years). The Merle dAubigne and Harris hip scores were used for clinical evaluation. In the long term follow up, severe or moderate pain was present in 38.6% of hips. Radiographs were studied and radiolucent lines, and other evidence of loosening, were recorded. Twenty hips (24.1%) showed radiological signs of loosening of the acetabular cup and a displacement of more than 5 mm in 37.3%. The loosening rate of femoral stems was 32.5%, but only 8.4% showed subsidence. The cumulative survival rate at 6 years was 84.1%, decreasing to 55.1% after the eleventh year. Complications and other aspects of the outcome are discussed. Our results were on the whole not satisfactory and we cannot recommend this type of uncemented endoprosthesis for routine total hip replacement.
