Femoral neck fracture increases 30-day mortality 16-fold and elevates mortality risk for up to 4 years: a matched cohort study of 3,246 patients

This study demonstrated that FNFs are associated with a markedly elevated short-term mortality risk, with patients experiencing a 16 times higher risk of death within 30 days compared with an age-, gender-, and comorbidity-matched group without an FNF. The excess risk was most pronounced during the first 3-6 months and persisted for up to 4 years before converging with the match group mortality rates.
