To assist surgeons performing pelvic osteotomies for the treatment of dysplastic hips, an image guided freehand navigation system has been developed. Preoperative computed tomographic scan images are presented in various ways to the surgeon together with real time display of the instruments and surgical action on the computer screen. The system supports the preoperative plan and provides optimized control of surgical action. The main focus of the image guidance has been placed on the execution of the different required cuts and the reorientation of the acetabular fragment. Special attention also has been given to the development of a sophisticated surgeon-machine interface. Fourteen surgeries have been performed with image guidance so far. The visualization aids provided by the system are able to help reduce potential risk and thus increase safety and accuracy for this difficult class of surgical interventions.
为协助外科医生进行骨盆截骨术治疗发育性髋关节，已开发出一种图像引导徒手导航系统。术前计算机断层扫描图像以多种方式呈现给外科医生，同时在计算机屏幕上实时显示器械和手术操作。该系统支持术前规划并提供手术操作的优化控制。图像引导的主要重点放在执行不同所需切口以及髋臼碎片的重新定位上。还特别关注了复杂的人机界面的开发。到目前为止，已在图像引导下进行了14例手术。该系统提供的可视化辅助工具能够帮助降低潜在风险，从而提高这类困难手术干预的安全性和准确性。
