目的通过标本研究计算机导航辅助下进行舟骨骨折微创内固定手术的可行性. 方法采用基于ISO-C3D影像的术中即时导航技术,结合自主研发的舟骨三维定位与导向框架,对2具成人上肢标本进行计算机导航辅助下舟骨经皮内固定手术.对手术标本进行大体和影像学评价,对导航手术的可行性进行评判. 结果本研究采用的术中即时三维影像系统结合舟骨经皮内固定框架导航手术系统,可在标本的腕关节上顺利进行舟骨经皮微创内固定手术.2具标本均一次完成舟骨导针的置入,内固定物位置位于舟骨安全区内. 结论本研究所采用的导航手术系统应用于舟骨经皮微创内固定手术的可行性,该导航系统的精确度和稳定性可满足舟骨经皮固定手术的要求.

Objective To investigate the feasibility of a new computer-assisted navigation frame for percutaneous scaphoid screw placement.Methods Two fresh cadaveric upper limbs were used for percutaneous scaphoid screw placement under ISO-C3D navigation system combined with a new positioning and guidance frame.The specimens were assessed grossly and radiologically.Results Scaphoid screw placement was performed successfully using this new navigation system.Only one attempt was required for percutaneous guide wire insertion and the screws were within the safe zone of the scaphoid for both of the specimens.Conclusion This preliminary study proved the feasibility of percutaneous scaphoid screw placement using this new computer-assisted navigation frame.The accuracy and stability of this system can meet the requirement of percutaneous scaphoid screw placement in this study.
