Objective To investigate the main factors in cannulated srew fixation of femoral neck fractures by the mechanical analysis of the curative effect of the closed reduction and internal fixation of the femoral neck fractures. Methods By August 2010 to October 2016,47 patients with femoral neck fracture by closed reduction with cannulated screw fixation in our orthopaedic were studied, through single and multiple factor analysis,and the factors concluded the sex,age,operation time,preoperative traction,reduction quality, postoperative full weight-bearing time, Garden Type, removal of internal fixation. Results Logistic regression model of femoral head necrosis risk factors include:age, reduction quality (P<0. 05 ) , and the rest are not significant. Conclusions The patient' s age,reduction quality were the main factors affecting the femoral neck fracture healing,the mechanical fixation effect of cannulated screw is a good foundation for fracture healing. Therefore,the doctor may select the proper reduction mode according to the patient's condition for a better therapeutic effect.%目的 通过闭合复位空心钉内固定治疗股骨颈骨折疗效的生物力学分析,探讨影响空心钉内固定治疗股骨颈骨折疗效的主要因素.方法 对2010年8月至2016年10月骨科收治的47例股骨颈骨折患者进行回顾性研究.所有股骨颈骨折患者均行闭合复位空心钉内固定治疗,对性别、年龄、手术时机、术前牵引、复位质量、术后完全负重时机、Garden分型、内固定是否取出等因素进行单因素和多因素分析.结果股骨颈骨折疗效的危险因素有:年龄、复位质量(P<0.05),其余指标均无统计学意义.结论 年龄、复位质量是影响股骨颈骨折临床疗效的主要因素,空心钉内固定的力学固定效应为骨折愈合打下良好的基础. 因此在临床股骨颈骨折的患者可根据患者的具体情况选择合适的治疗方案,以取得更好的治疗效果.
