摘　　要：目的探讨3种不同导针定位方案在股骨颈骨折老年患者空心螺钉内固定治疗中的应用价值,为其临床应用提供可参考依据。方法共纳入120例股骨颈骨折老年患者作为研究对象,采用随机数字法平均分为3组,在空心螺钉内固定治疗导针定位时分别采用新型导针定位器定位(新型组)、普通导针定位器定位(普通组)及徒手导针定位(徒手组)。比较3组患者手术时间和螺钉平行度等,并随访1年。采用Harris评分系统对患者术后关节功能进行评价。结果新型组手术时间、导针置入次数低于普通组与徒手组,新型组正侧位螺钉平行度及骨折愈合时间低于徒手组,而螺钉分布面积大于普通组与徒手组,差异有统计学意义(P<0.05);普通组导针置入次数、正侧位螺钉平行度及骨折愈合时间低于徒手组,而螺钉分布面积大于徒手组,差异有统计学意义(P<0.05)。结论新型导针定位器定位有较好的透视性及可调节性,可促进导针的准确定位,进而使空心螺钉更好地固定,避免反复定位及穿刺,减少了手术创伤,值得临床推广应用。【Objective】 To explore the clinical effect of conductivity needle positioning in elderly patients with femoral neck fracture. 【Methods】 One hundred and twenty elderly patients with femoral neck fracture were included. All the patients were divided into new group（new type of needle locator positioning）, normal group（ordinary needle locator positioning） and unarmed group（unarmed needle positioning）. The operation time and screw parallel degree were compared, and Harris scoring system was used to evaluate the knee function after surgery. The patients were fallowed up for one year. 【Results】 The operation time was shorter and the number of needle placement times was smaller in the new group than in the normal group and the unarmed group with significant differences（P〈0.05）. The screw parallel degree at anterioposterior side and the lateral side was less and the fracture healing duration was shorter in the new group than in the unarmed group with statistical differences（P〈0.05）. The distribution area of screw in the new group was larger than that in the normal and the unarmed groups, the differences were statistically significant（P〈0.05）. The number of needle placement times was smaller, the screw parallel degree at anterioposterior side and the lateral side was less and the fracture healing duration was shorter in the normal group than that in the unarmed group with significant differences（P〈0.05）. The distribution area of screw in the normal group was larger than that in the unarmed group, the difference was statistically significant（P〈0.05）. 【Conclusions】 The new type of needle locator positioning has better perspectivity and adjustability, which can promote accurate needle positioning and make better fixation of hollow screw.
