Radiological assessments identified radio-lucent lines, spot welding, pedestal formation and migration in order to assess fixation and stability of the femoral stem according to Engh’s criteria. DeLee and Charnley zones were used to assess loosening of the ace tabular cup. Subsidence, migration and cup-angle were also measured. The criteria for failure was revision or impending revision due to either pain, septic or aseptic loosening.
We describe the survival at 10 years of 134 consecutive JRI Furlong H.A.-coated uncemented total hip replacements. The follow-up was a minimum of 10 years (10.5 to 12.0 years). Patients were assessed by clinical and radiological means. We used Merle d’Aubigné and Postel clinical score. Radiological assessments identified radio lucent lines, spot welding, pedestal formation and migration in order to assess fixation and stability of the femoral stem according to Engh’s criteria. DeLee and Charnley zones were used to assess loosening of the ace tabular cup. Subsidence, migration and cup-angle were also measured. The criteria for failure was revision or impending revision due to either pain, septic or aseptic loosening. The mean results of the Merle d’Aubigné and Postel score were 7.4 pre-op. and 15.9 post-op. None of the acetabular cups in this series were revised. No femoral stem was revised for loosening. Six patients were lost to follow-up. Of the 128 femoral stems reviewed, only 1 was revised for periprosthetic fracture following a fall.
