摘要
目的探讨透视图像导航技术在股骨髓内钉治疗股骨干骨折中的临床应用。方法应用连接在标准扩髓股骨交锁髓内钉器械上的适配器,透视图像导航可辅助完成手术中的髓内通道的入点选择、髓内钉置入、近端及远端锁钉的置入。结果16例股骨干骨折的应用结果令人满意。平均手术时间为48.8min,平均X线图像采集5.5次,平均出血量160ml,平均骨折愈合时间16.8周。手术中和手术后无并发症发生。结论肯定了透视图像导航技术在扩髓股骨交锁髓内钉手术中应用的可行性。手术中只需1次X线成像就能做出虚拟的手术环境和路径;导航的瞬时追踪功能,使术者的手术工具做到实时监测,减少了X线照射量、缩短了手术时间、提高了髓内钉置入的准确度、减小了手术创伤。
Objective To explore the clinical application of fluoro-navigation in the fixation of femoral fracture with interlocking nail.Methods With the adapters attached to standard femur interlocking nail,the fluoro-navigation system was used to guide the entry of the medullary canal,nail insertion and the proximal and distal locked screw insertion.Results The results of 16 femoral fracture fixations were satisfactory.The average duration of surgery was 48.8 minutes.The mean X-ray image collection was 5.5 times.No complication was found during and after surgery.Conclusion Its confirmed that the application of fluoro-navigation in femur interlocking nail decrease X-ray exposure,shorten operation time,improve accuracy of implant insertion and cause less surgical traumas.
