Key result
Total hip arthroplasty for femoral neck fracture was associated with approximately double the early mortality risk compared to a matched control population (adjusted HR 2.2; 95% CI 2.0-2.4).

Elevated early mortality after THA for femoral neck fracture warrants careful risk stratification and counseling; leaves open whether THA adds risk beyond fracture and frailty.
Cohort (n=143,217)
Yes
Does total hip arthroplasty for femoral neck fracture increase early mortality compared to a matched control population?
Hazard Ratio: 2.2 (95% CI 2–2.4)
Absolute Event Rate: 96.3% vs 98.7%
Early mortality in femoral neck fracture patients undergoing THA is approximately double that of a matched control population, with the highest risk in those >80 years or with significant comorbidities.
Hailer et al. (2016) conducted a cohort in Femoral neck fracture (n=143,217). Total hip arthroplasty (THA) vs. Matched control population was evaluated on 90-day survival (HR 2.2, 95% CI 2.0-2.4). Total hip arthroplasty for femoral neck fracture was associated with approximately double the early mortality risk compared to a matched control population (adjusted HR 2.2; 95% CI 2.0-2.4).
