Mortality After Femoral Neck Fractures: A Two-Year Follow-up

Abstract

Background and Objective. To identify the survival and standardized mortality ratio with respect to gender, age, and treatment method of patients treated for femoral neck fractures. Material and Methods. A retrospective review of medical records of 736 patients treated for femoral neck fractures at Vilnius University Emergency Hospital during 2004–2006 was carried out. Results. The overall 1- and 2-year survival rates were 77.4% and 67.1%, respectively. Lower survival rates were observed in the internal fixation group than in the primary and secondary total hip arthroplasty groups (63.2% vs. 72.0% and 75.1%). Cox proportional hazards model analysis showed patient age to be a significant risk factor for survival (hazard ratio, 1.05; 95% CI, 1.04– 1.07; P<0.001). The overall standardized mortality ratio was 2.50. The standardized mortality ratios for men and women were 3.07 and 2.27, respectively, but the difference between these groups was not significant. Conclusions. Standardized mortality and survival rates decreased with increasing patients’ age. Significantly lower survival rates were documented in the internal fixation group as compared with primary and secondary total hip arthroplasty groups. There was a trend toward a higher standardized mortality ratio in men than women, but the difference was not significant.

RETRACTED ARTICLE: Open reduction and closed reduction internal fixation in treatment of femoral neck fractures: a meta-analysis

“…The incidence of femoral neck fracture is increasing at an exponential rate as a result of the longevity of the general population [ 2 ]. It is one of the most common consequences of injuries in the elderly population [ 3 ]. Despite advances in surgical techniques and medical care, the risk of nonunion and avascular necrosis (AVN) of femoral head after fixation have not changed appreciably in the last 50 years [ 4 ].…”

The impact of hip fracture on mortality in Estonia: a retrospective population-based cohort study

“…Estimates of hip fracture mortality in Eastern Europe are scarce [ 10 , 11 ]. However, the data in this region suggests a sex-specific difference in the incidence of hip fractures between Eastern and Western Europe [ 12 – 14 ], and the age and sex-specific all-cause mortality rates in Eastern Europe differ from those in Western countries [ 15 ].…”

Estonian hip fracture data from 2009 to 2017: high rates of non­operative management and high 1-year mortality

“…Multiple studies, including a systematic review, have reported lower mortality rates at 1 year than the Estonian rate at 6 months (Kurtinaitis et al. 2012, Diamantopoulos et al. 2013, Brozek et al.…”
