Abstract
Objective To analyze the influencing factors of fracture nonunion after PFNA in patients with intertrochanteric fractures.Methods 126 cases of femoral intertrochanteric fractures treated with PFNA in our hospital from March,2018 to January,2019 was performed.According to the patients' 1 month postoperative X-ray examination of fracture healing,they were divided into a fracture nonunion group(n=12)and a fracture healed group(n=114).The basic data,such as gender,age,fracture cause,fracture classification,and comorbidity,were compared between the two groups.Unconditional logistic regression was used to analyze the multiple factors.The possible influencing factors were analyzed.Results There were statistical differences in age,fracture stability,insufficient screw depth,and poor screw position between the two groups(all P ＜ 0.05).Unconditional logistic regression analysis showed that age,fracture stability,insufficientscrew depth,poor screw position,and operation time were the risk factors for nonunion of after PFNA for femoral intertrochanteric fracture(all OR ＞ 1;all P ＜ 0.05); and fracture stability was a protective factor for fracture healing after PFNA for intertrochanteric fracture(OR ＜ 1; P ＜ 0.05).Conclusion Age,intraoperative screw placement depth,and screw position are independent risk factors for fracture nonunion after PFNA for intertrochanteric fracture Fracture stability is a protective factor for fracture healing.Relevant risk factors should be clinically known well,and relevant prevention and tratment work should be done.关键词
