Early Functional Outcome of Total Hip Arthroplasty in Elder Patients with Displaced Femoral Neck Fractures

Background: Displaced femoral neck fractures in elderly patients pose a significant orthopedic challenge due to their association with high morbidity and mortality rates. Effective management of these fractures is crucial to improving patient outcomes and quality of life. Total hip arthroplasty (THA) is considered a beneficial surgical intervention, offering superior functional outcomes and lower complication rates compared to other treatments. Objective: To determine the early functional outcome of total hip arthroplasty in elderly patients with displaced femoral neck fractures. Methods: This descriptive study included sixty patients aged 50 to 80 years with displaced femoral neck fractures, treated with total hip arthroplasty at Hayatabad Medical Complex from October 2023 to April 2024. Preoperative assessments included radiographs and various blood tests. Functional outcomes were measured using the Harris Hip Score (HHS) at six months postoperatively. Data were analyzed using SPSS version 26, and the paired t-test was used to compare preoperative and postoperative HHS scores, with P ≤ 0.05 considered significant. Results: The mean age of the sixty patients was 64.80±9.08 years. The mean preoperative HHS was 74.42±10.49, which significantly increased to 84.95±8.65 at the six-month follow-up (P = 0.0001). Postoperative complications included infections in 2 patients (3.3%) and hip dislocations in 3 patients (5%). No complications were observed in 55 patients (91.7%). Conclusion: Total hip arthroplasty is an effective procedure for elderly patients with displaced femoral neck fractures, demonstrating significant improvements in functional outcomes and a low incidence of complications.
