| Popis: | Background The purpose of this study is to determine the clinical and radiographic outcomes, mortality rate, complication rate, and revision rate of this ultra-short non-anatomic cementless femoral stem in elderly patients with a femoral neck fracture. Methods We reviewed the results of 284 total hip arthroplasties performed with an ultra-short non-anatomic cementless stem in 280 previously active patients with a mean age of 72.8 ± 13 years (range 49-83). The mean follow-up was 9.3 years (range 7-13). Results The mean Harris Hip Score was 86 ± 14 points at final follow-up. The mean Western Ontario and McMaster Universities Osteoarthritis Index score was 24 ± 6 points at the final follow-up. The mean University of California, Los Angeles activity score was 6 points at final follow-up. Osseointegration was seen in all acetabular (100%) and in 276 femoral components (97%). Kaplan-Meier survivorship analysis revealed that the survival rate of the femoral component at 8.3 years was 97% (95% confidence interval 91–100) and that of the acetabular component was 100% (95% confidence interval 94–100) with aseptic loosening or revision as the end point. Conclusion An ultra-short non-anatomic cementless femoral stem in patients with good bone quality (Dorr A and some Dorr type B bone) is a safe treatment for femoral neck fracture. In patients with poor bone quality (Dorr C type), the results were very poor, and use of this stem should be avoided. |
