Hemiarthroplasty Versus Total Hip Arthroplasty for Femoral Neck Fracture in the Elderly: An Analysis from the American Joint Replacement Registry.
Introduction: Debate persists regarding management of displaced femoral neck fractures in elderly patients with either total hip arthroplasty (THA) or hemiarthroplasty (HA). We investigated the United States (US) experience by comparing revision risk following THA or HA using the American Joint Replacement Registry (AJRR) in elderly femoral neck fractures.
Methods: Between 2012 and 2020, we identified 65,958 patients within the AJRR who were treated for a femoral neck fracture with arthroplasty. All were Medicare beneficiaries aged 65 years and older with a minimum potential follow-up of two years. The mean age was 82 years, and 69% were women. Total hip arthroplasty was utilized in 12,537 (19%). Hemiarthroplasty was used in 53,421 (81%), of which 58% were bipolar constructs. Dual-mobility constructs were used in 11% of THAs. Femoral components were cemented in 38%. A Cox proportional hazards model and a competing risk analysis were performed. Analytic groups included THA, THA with dual-mobility, bipolar HA, and unipolar HA. The mean follow-up was five years.
Results: The 5-year cumulative risk of any revision was 3.2%. There were no significant differences in revision risk when comparing bipolar HA to unipolar HA, standard THA, or dual-mobility THA. Revision risk was not statistically different between unipolar HA and THA or dual-mobility THA. Older age and the use of cemented femoral components were associated with a reduced risk of revision (P < 0.0001), while patients with a higher comorbidity index sustained more revisions (P < 0.05).
Conclusion: Elderly patients who have displaced femoral neck fractures in the United States have a similar risk of revision whether they are treated with a THA or HA. However, this does not account for surgeon bias, host-related factors, and other technical features such as approach, limb length, and offset. Surgeons should base the procedure on the patient's functional demands and comorbidities.
期刊介绍：
The Journal of Arthroplasty brings together the clinical and scientific foundations for joint replacement. This peer-reviewed journal publishes original research and manuscripts of the highest quality from all areas relating to joint replacement or the treatment of its complications, including those dealing with clinical series and experience, prosthetic design, biomechanics, biomaterials, metallurgy, biologic response to arthroplasty materials in vivo and in vitro.
