Fixation-specific modeling of age-frailty interactions to predict early mortality after hip fracture surgery.

BACKGROUND Early mortality after hip fracture surgery remains high. Existing risk models treat age and frailty as independent predictors and may not reflect how physiologic reserve modifies risk across fixation strategies. We evaluated whether modeling age-frailty interactions improves estimation of 30-day mortality....

Predicting 5-Year Mortality After Prosthetic Joint Infection Using a 30-Item Accumulated Frailty Index in a 13,371-Patient Multicenter Cohort

Background Prosthetic joint infection (PJI) involves a significant mortality risk, with 26-30% of patients dying within 5 years. Current risk assessment tools offer limited prognostic accuracy for PJI patients. This study aimed to develop a prognostic model for 5-year all-cause mortality after PJI using age and frailty...
