移位截骨术是一种通过矫正基于骨骼的小腿轴线异常移位来解除受损关节负荷的手术方法。为此，胫骨或股骨被切割并固定在机械和生理上合理的位置。目前在截骨术中使用的传统切割技术会造成生理上的缺陷，例如由于刀具的热量传递而导致骨骼变性。由于愈合时间短，切割轮廓定位准确，使用自动冷切削工艺比传统方法更可取。为临床应用做好准备，建立了实验手术室。由于生理原因，AWIJ工艺被修改为包括镁悬浮液。该工具由一个工业机器人引导，通过光学导航系统进行控制。软组织由专门为此应用开发的喷射吸入器保护。最后，可以进行逼真的焦点穹顶截骨术。由WJTA®-IMCA®组织和赞助
Displacement osteotomy is an operative method for the load relieving of pre-damaged joints through the correction of skeletally-based abnormal displacement of the leg axes. For this purpose, the tibial or femoral bone is cut and fixed in a mechanically and physiologically reasonable position. Conventional cutting techniques used in osteotomy today cause physiological disadvantages, such as the denaturation of bone caused by heat transmission from the tool. Due to a short healing time and an exact positioning of the cutting contour, the use of an automatable cold cutting process is preferable to conventional methods. In preparation for clinical application, an experimental operating room was set up. For physiological reasons, the AWIJ process was adapted to include a magnesium suspension. The tool was guided by an industrial robot, controlled through an optical navigation system. The soft tissue was protected by a jet absorber developed specifically for this application. Finally, a realistic focal dome osteotomy cut could be carried out. Organized and Sponsored by WJTA®-IMCA®
