摘　　要：目的阐述透视导航技术在长骨干(股骨和胫骨)骨折,特别是在术中远端交锁髓内钉固定中的应用。探索在导航条件下术中应用髓内钉图像库开展远端交锁固定的可行性。此外,医用机器人的开发旨在被进一步用来改善手术程序的精确性。方法导航手术下,55例行股骨远端交锁钉固定和36例行胫骨远端交锁钉固定。其中13例术中应用图像库开展远端交锁固定。结果远端交锁固定成功率为97%。结论透视导航在长骨干骨折术中,使远端髓内交锁钉固定成功率增高。图像库的应用可以进一步减少患者和手术人员的X线辐射剂量。Objective This paper illustrates the application of fluoronavigation in intramedullary nailing in long bone fractures (femur and tibia), especially during the procedure of distal locking. We also explore the possibility of distal locking with an image bank of intramedullary nails and under navigation. Furthermore medical robots are being developed to further improve the precision of the procedure. Methods In our hospital, distal locking in 55 cases of femoral nailing and 36 cases of tibial nailing were performed under navigation. Another 13 cases of distal locking were performed with the image bank. Result The overall successful rate of distal locking was 97%. Conclusions Fluoronavigation in distal locking of intramedullary nailing of long bone fractures has achieved a high successful rate. Development of an image bank could further decrease the X-ray exposure suffered by the patient and operation theater staffs.
