[Analysis of mortality and its predictors in patients with contralateral hip fracture after femoral neck fracture].

INTRODUCTION: There is a high mortality with not well understood risk factors after the second hip fracture.

AIM: Analysis of the 30- and 365-day mortality and its risk factors in patients with contralateral hip fracture.

METHOD: Patients with contralateral hip fracture between 01 Jan 2000 and 31 Dec 2008 were identified among those who suffered their primary hip fracture in Hungary in 2000. Risk factors as age, sex, concomitant and chronic diseases, type of fracture and surgery, surgical complications, day of admission were analyzed by logistic and Cox regression as well as Kaplan-Meier analysis.

RESULTS: There were 312 eligible patients identified with 8.3 % mortality rate at 30 and with 38,4% at 365 days respectively. Significant risk factors for the 30 day mortality were intertrochanteric type of fracture (OR: 4.722; HR: 4.129) and non operative management (OR: 7.357; HR: 6.317) while for the 365 day mortality those were older age (OR:1.070; HR:1.050) and type of surgery (OR: 0.450).

CONCLUSION: Age, type of fracture and type of surgery proved to be risk factors. There is a need to identify further risk factors in order to develop an efficacious prevention strategy for the reduction of the mortality after the second hip fractures. Orv Hetil. 2017; 158(20): 783-790.
