Frailty Assessment in Total Hip Arthroplasty for Femoral Neck Fracture

Purpose: When managing femoral neck fractures, National Institute for Health and Care Excellence guidelines (2023) recommend total hip arthroplasty (THA) for patients who are expected to independently perform activities of daily living (ADLs) beyond two years. These attempt to clarify the indication for THA versus hemiarthroplasty (HA). Frailty assessment tools, such as the Rockwood Frailty Scale (RFS), may provide surgeons a more objective means to assess patient function. The aim of this study is to ascertain whether frailty assessments are predictive of mortality associated with THA thus helping determine arthroplasty suitability. Materials and Methods: Single-center data was collected retrospectively between 2014 and 2020. Three hundred thirty-three cases were eligible for review. For the RFS, Johns Hopkins Frailty Assessment (JHFA) and Nottingham Hip Fracture Score (NHFS), frailty scores were generated and 2-year mortality was calculated for 'frail' and 'non-frail' patient cohorts. Results: =0.054). Conclusion: This study demonstrates that following THA for femoral neck fractures, preoperative frailty scores are predictive of 2-year postoperative mortality. Frailty assessments could objectively guide surgical decision making with respect to offering THA versus HA.
