PURPOSE: To compare the postoperative survival and mortality rates in intertrochanteric femoral fracture (IFF) patients who underwent either open reduction internal fixation (ORIF) or hip arthroplasty. METHODS: Clinical data from senior patients who had IFF and underwent ORIF or hip arthroplasty were analyzed retrospectively. Survival curves were compared between groups with Kaplan-Meier method and log-rank test. Significant independent prognostic factors were identified by Cox multivariate regression analysis. RESULTS: All patients recovered fully post-surgery. Although 31 patients died during the follow-up period (ORIF, mean 45.4 months; arthroplasty, mean 51.6 months), mortality rate did not differ significantly between the groups. The 1-yr and 2-yr survival rate estimates for the ORIF group were 92.2%, and 86%, respectively; they were 85% and 74% for the arthroplasty group. Average survival lengths for ORIF and arthroplasty groups were 88 and 67 months, respectively. The effect of surgical approaches on survival differed significantly (log-rank test c2 = 6.402, p = 0.011). Multivariate Cox regression model indicated that surgical choice (p = 0.036) was a significant independent risk factor for the prognosis of senile IFF, even with adjustment for age (p = 0.002). CONCLUSION: The overall postoperative prognosis was superior in senile IFF patients treated with ORIF.
