Abstract Objective To analyze the influencing factors of femoral head necrosis after closed reduction and internal with cannulated compression screws of femoral neck fracture.Methods A total of 118 patients with femoral neck fractures underwent closed reduction and cannulated compression screws were selected according to the inclusion criteria.Statistical analysis was performed on 9 factors including age,gender,ethnicity,fracture Garden classification,timing of surgery,Garden's alignment index,triglyceride,total cholesterol and low density lipoprotein,and analyzed the relationship between femoral head necrosis and closed reduction and internal withcannulatedcompression screws of femoral neck fracture.Results According to the t-test or chi-square test of 9 factors,there was no statistical significance of femoral head necrosis after femoral neck fracture internal fixation with ethnicity and total cholesterol.Age,gender,fracture Garden classification,timing of surgery,Garden's alignment index,triglyceride,lowdensity lipoprotein were statistically significant.According to binary logisticanalysis,gender,triglyceride was not statistically significant,but age,Garden classification,timing of surgery,Garden's alignment index,low density lipoprotein has statistical significance.Conclusion For femoral neck fractures,age,fracture Garden classification,timing of surgery,Garden'salignment index,and lowdensity lipoprotein are risk factors for femoral head necrosis after closed reduction and internal withcannulatedcompression screws of femoral neck fracture.
