股骨转子间骨折患者内固定治疗发生髋内翻的危险因素分析

目的 探讨股骨转子间骨折患者行内固定术治疗后发生髋内翻的危险因素，为股骨转子间骨折患者的临床治疗和护理提供理论支持。 方法 回顾性分析2010年1月—2014年12月间盘锦市中心医院收治的159例股骨转子间骨折患者的临床资料。纳入标准:经影像学确诊为股骨转子间骨折；骨折均为新鲜闭合性骨折；患者非病理性或其他类型骨折；患者意识清醒且无精神疾病。对患者临床均给予内固定术治疗，术后患者一期愈合。依据患者术后是否发生髋内翻，将患者分为髋内翻组和无髋内翻组。制作危险因素调查表，收集2组患者性别、年龄、体质量指数、骨密度、骨折分型、内固定术、小转子复位、负重时间等因素资料。采用单因素和Logistic回归分析对收集的数据进行分析。 结果 159例骨转子间骨折患者术后24例发生髋内翻，髋内翻发生率为15.1%。单因素和Logistic回归分析发现年龄、体质量指数、骨密度、骨折分型、小转子复位、负重时间是股骨转子间骨折患者内固定术后发生髋内翻的危险因素。 结论 股骨转子间骨折患者内固定术后易发生髋内翻，年龄、体质量指数、骨密度、骨折分型、小转子复位、负重时间是股骨转子间骨折患者内固定术后发生髋内翻的危险因素。 

Risk factors for coxa varus in intertrochanteric fracture patients performing internal fixation treatment

Objective To investigate the risk factors of coxa varus in intertrochanteric fracture patients treated by internal fixation to provide support for treatment and nursing on intertrochanteric fracture. Methods Total 159 cases of intertrochanteric fracture patients treated by internal fixation from January,2010 to December,2014 in our hospital were retrospectively analyzed.Inclusion criteria:diagnosed as intertrochanteric fractures by imaging;fresh closed fracture;non-pathological fracture or non-other types fracture;conscious and without mental illness.The patients were clinical treated with internal fixation for the treatment and healed at one period.Based on the postoperative varus status,patients were divided into varus group(24 cases) and non-varus group(135 cases).The risk factors questionnaire was made,and patients gender,age,body mass index,bone mineral density,fracture type,internal fixation method,lesser trochanter reseting status,loading time of two groups were selected.The Univariate and Logistic regression analysis were used to analyze the dates. Results In all 159 cases patients,24 cases were with coxa varus,and the varus rate was 15.1%.Univariate and Logistic regression analysis showed that age,body mass index,bone mineral density,fracture type,small rotor reset,load time were the risk factors of coxa varus in intertrochanteric fracture patients treated by internal fixation. Conclusion After intertrochanteric fracture fixation,coxa varus is common;and age,body mass index,bone mineral density,fracture type,small rotor reset,load time are the risk factors of coxa varus in intertrochanteric fracture patients treated by internal fixation.
