手术并发症，如愈合问题，在使用Arbeitsgmeinschaft fore OsteSynthefragen(AO)技术治疗骨折时，给患者带来了功能和经济上的挑战，也给外科医生带来了治疗难题。以生物接骨为核心的微创计算机辅助骨科手术是骨折治疗的一个新方向。方法通过引入新的复位策略、构建新的系统结构和升级相应的软件，对六足计算机辅助骨折复位系统进行了改进。然后，我们使用牛股骨的骨折模型对整个系统进行了验证。结果对横断骨折的牛股骨进行了7次精度测试。残差：轴向偏转1.230.60 mm，平移1.04+/-0.47 mm，角度2.34+/-1.79度，旋转2.83+/-0.96度。可拆卸的模块化设计将允许在未来进行更多类似的应用。版权所有(C)2014 John Wiley&Sons，Ltd.
BackgroundSurgical complications such as healing problems, in fractures treated using the Arbeitsgemeinschaft fur Osteosynthesefragen (AO) technique, present functional and economic challenges to patients and treatment dilemmas for surgeons. Computer-assisted orthopaedic surgery using minimally invasive techniques focused on biological osteosynthesis is a novel direction for fracture treatment.MethodWe modified the hexapod computer-assisted fracture reduction system by introducing a new reduction strategy, building a new system configuration and upgrading the corresponding software. We then validated the entire system, using a fracture model of bovine femur.ResultsPrecision tests were performed seven times on a bovine femur with a transverse fracture. Residual deviation was 1.230.60mm in axial deflection, 1.04 +/- 0.47mm in translation, 2.34 +/- 1.79 degrees in angulation and 2.83 +/- 0.96 degrees in rotation.ConclusionOur new reduction system described here is detachable, flexible and more precise in coordinate transformations. The detachable, modular design will allow for more analogous applications in the future. Copyright (c) 2014 John Wiley & Sons, Ltd.
