无需影像导航系统在矫形外科的应用

Imageless navigation systems in orthopaedic surgery

近年来,无需影像的导航系统发展迅速,已经成为临床上主要的导航系统。该系统由计算机主机、红外线光学定位系统、脚踏控制板和导航软件组成。目前其在矫形外科方面已经成功用于人工膝关节置换、人工膝关节单髁置换、人工髋关节置换、人工髋关节表面置换、人工肩关节置换、膝前交叉韧带重建和膝关节周围截骨。从1997-01Saragaglia等采用首个无需影像的OrthoPilot系统导航人工膝关节置换以来,已经有大量的临床研究报告。总的来说,临床结果表现在此类系统的导航手术比传统手术提高了精确度,减少了超出理想范围的病例。研究表明其与CT影像为基础的导航系统具有相当的精确度,可以作为标准的导航系统在临床上常规使用。

Recently imageless navigation systems have been developed rapidly, and have become major navigation system in clinic. It comprises computer workstation, infrared optical localizing system, foot control pedal and navigation software. Currently, imageless navigation systems have been used successfully in total knee arthroplasty, uni-compartment arthroplasty, total hip arthroplasty, hip surfacing arthroplasty, total shoulder arthroplasty, anterior cruciate ligament reconstruction and peri-articular osteotomy of knee, etc. The first OrthoPilot imageless navigation system was used by Saragaglia et al in total knee arthroplasty in January 1997, and many clinical studies have been conducted. The clinJcal results show that this kind of systems greatly improves operative accuracy, and reduce cases beyond ideal range. It shows accuracy as CT-based navigation systems, and they can be commonly used as standard navigation systems in clinic.
