• INTRODUCTION
    • Due to demographic changes, the annual incidence of femoral neck fractures (FNF) in patients reaching the 9th and 10th decade of life is increasing. Although active and cognitively intact elderly patients could benefit from total hip arthroplasty (THA) in case of a FNF, there is no clear consensus on whether THA should be performed in this particular subgroup of patients with very advanced age. The purpose of this study was to report the complication rate, mortality, clinical outcomes and quality-adjusted life year (QALY) gained in patients treated with total THA for FNF, while having exceeded the mean life expectancy at the time of surgery, compared to a younger control group.
  • MATERIALS AND METHODS
    • Patients treated with THA through a direct anterior approach (DAA) for FNF and exceeding the average life expectancy in Switzerland (age ≥ 83 y, n = 45) were matched for gender, body mass index (BMI) and ASA score with patients under the age of 83 (age = 65-83, n = 45). Perioperative complications, clinical and radiologic outcomes, as well as mortality were compared between groups.
  • RESULTS
    • Total complication rate did not differ significantly with 22.2% in the older group compared to 17.8% in the control group. The 30-day and 1-year mortality was slightly but not significantly higher in the older group (2.2% and 8.9% vs. 2.2% and 2.2%). The average QALY gained was 3.4 years and 4.1 years for the older group and their younger counterparts, respectively.
  • CONCLUSION
    • THA through the DAA for FNF in cognitively intact and active patients might be a credible and safe option even after reaching mean life expectancy with excellent functional outcomes and similar surgery-related complications compared to patients younger than 83 years. Our results imply that an advanced age should not be considered a contraindication for THA in case of a FNF.
