[PATIENTS' AGE AS A PREDICTOR FOR FRACTURE PATTERN AND POST-OPERATIVE MORTALITY IN PERTROCHANTERIC FRACTURES].

Introduction: Fragility hip fractures are a major cause for morbidity and mortality in the elderly population. Half of these fractures occur in the intertrochanteric area.

Aims: To evaluate the correlation between the patients' age and the intertrochanteric fracture pattern, as well as the correlation between the patients' age, fracture pattern and the risk for 1-year post-operative mortality.

Methods: A retrospective cohort study of patients who underwent osteosynthesis for intertrochanteric fractures in the Kaplan Medical Center between 2010-2013. Demographic data, including 1-year survival was gathered. An analysis of patients X-ray imaging at presentation was performed and fractures were classified according to the AO classification system and for fracture stability. A regression model was used to evaluate for the correlation between patients' age and fracture patterns and for predictors of 1-year survival.

Results: Overall, 644 patients were treated during the study period, of whom 544 met the inclusion criteria. Patients' age did not correlate either with the fractures AO classification or with fracture stability. Male sex and age were found to relate with increased mortality risk, as men have OR of 1.77 for mortality (95% CI 1.079- 2.603, p.= 0.022) and each additional year increased mortality by 8.3%.

Conclusions: The patients' age did not correlate with fracture pattern and stability. Increasing age and male sex were found to be associated with reduced 1-year survival following surgery.
