90 Research Day 2020 Barzilai University Medical Center 65 STABILITY PREDICTORS FOR WEIGHT BEARING IN TROCHANTERIC HIP FRACTURES. Maria Oulianski, Ruslan Sokolov, Omri Lubovsky Department of Orthopedy, Barzilai University Medical Center, Ashkelon Faculty of Health Studies, Ben Gurion University of the Negev, Beer Sheva, Israel Background Trochanteric femur fractures in the older population defined as unstable for weight-bearing. These fractures increase the morbidity and mortality of this population, mainly due to a lack of mobility. There is no definition of unstable fracture, and the luck of classification methods for postoperative weight-bearing instructions, have the potential to affect the patient's ability for rehabilitation, morbidity, mortality, direct health care costs, and length of hospital stay. Currently, there is no universal definition for future prediction of success or failure for fixation of trochanteric fractures. Hypothesis The ability to predict weight-bearing in patients with trochanteric fractures after internal fixation, in the immediate clinical post-operative period. Objectives Identification of clinical and radiological criteria, which may cause failure or success of trochanteric fracture fixation in terms of clinical and radiological criteria at first days after surgery and during the surveillance period and the examination of the correlation between fracture stability and post-surgical pain. Results 86 patients among them: 45 diabetics, 77 hypertensives, 47 osteoporotic. 68 patients (70%) recommended to step on the operated leg during the immediate post-operative period. 34 were able to bear weight immediately. A successful fixation observed in 96% of patients. A direct correlation found between the mobility of patients before surgery, and the ability to bear weight after, and successful radiological outcome in the long-term follow-up. A negative predicting factor observed in patients who have diabetes. Diabetic patients had 80% in the decrease rate of weight-bearing in the immediate post-operative period. Conclusions The presence of diabetes may predict the failure to bear weight during the first post-surgical days, an inverse correlation found between the age and the ability to bear weight at the immediate postoperative period. A positive correlation was seen between the mobility of patients before fracture and long term successful radiological outcome of fixation.
