对于年轻和活跃的患者来说，金属对金属髋关节表面置换术是全髋关节置换术的替代方案，能够保留完整的股骨，从而改善未来髋关节置换术的预后。后续研究表明，早期种植失败的主要原因是种植体柄相对于股骨颈轴的方向错误、股骨头准备过程中股骨颈的缺口以及种植后松质骨的暴露。一种用于股骨髋关节置换植入物植入的计算机辅助规划和导航系统已经开发出来，该系统在术中基于透视的植入物定位规划和导航过程中为外科医生提供支持。本文介绍了为评估系统的功能和准确性而进行的尸体研究的结果。
Metal-on-metal hip resurfacing arthroplasties represent an alternative to total hip arthroplasties for young and active patients, enabling the preservation of intact femoral bone and therefore improving the prognosis for future hip joint replacements. Follow-up studies have shown that the main reasons for early implant failure are mal-orientation of the implant stem in relation to the femoral neck axis, and notching of the femoral neck during femoral head preparation, as well as by exposed cancellous bone after implantation. A computer-assisted planning and navigation system for the implantation of femoral hip resurfacing implants has been developed which supports the surgeon during intraoperative fluoroscopy-based planning and navigation of implant positioning. This paper presents the results of a cadaver study performed to evaluate the system's functionality and accuracy.
