Radiologically, all hips were assessed for migration and osteolysis, THAs for polyethylene wear and BHRs for a pedestal sign. Patient-reported outcomes, mortality and revision rates were compared.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The mean follow-up of the patients with a hybrid THR was 19.9\u2009years and for those with a BHR, 17.6\u2009years. 13 patients with a hybrid THR and 5 with a BHR had died. 1 hybrid THR and 3 BHRs were lost to follow-up. The revision rate of the hybrid THRs was 14\/54 and of the BHRs 6\/54. Log rank comparison of Kaplan-Meier survival estimates demonstrated a significantly lower mortality in the BHR group ( p = 0.039; hazard ratio [HR] = 0.37 [95% CI, 0.15\u20130.95]) but a non-significant difference in revision rates ( p = 0.067; HR = 0.43 [95% CI, 0.18\u20131.06]). The BHRs recorded superior OHS ( p = 0.03), UCLA ( p = 0.0096), and EuroQol visual analogue scores ( p = 0.03). Significantly more BHRs had run, played sport and undertaken heavy manual labour in the month preceding follow-up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>After 18\u2009years, patients with BHRs remained more active with a lower mortality rate but demonstrated no significant difference in revision rates.
