我们评价了传统手锉和机器人铣削对非骨水泥型全髋关节置换术的临床和影像学结果的影响，使用相同的基于计算机断层扫描（CT）的三维术前计划，使用ROBODOC工作站（Integrated Surgical Systems，Davis，Calif）。机器人铣削组包括78个髋关节，手动锉削组包括78个髋关节。使用ROBODOC工作站重建的最准确的CT图像评价术前计划和术后CT数据的放射学发现。机器人铣削组在2年时显示出显著的上级Merle D'Aubigne髋关节评分。在机器人铣削组中，没有术中股骨骨折，并且获得了影像学上的上级植入物匹配。手动粗锉可能导致术中股骨骨折、股骨柄尺寸过小、意外较高的垂直就位和意外股骨前倾，从而导致植入物匹配性较差。
We evaluated the effects of conventional hand rasping and robotic milling on the clinical and radiographic results of cementless total hip arthroplasty, with the same computed tomography (CT)-based 3-dimensional preoperative planning using a ROBODOC workstation (Integrated Surgical Systems, Davis, Calif). The robotic milling group consisted of 78 hips, and the hand-rasping group 78 hips. The radiographic findings from the preoperative planning and postoperative CT data were evaluated using the most accurate CT images reconstructed by the ROBODOC workstation. The robotic milling group showed significant superior Merle D'Aubigne hip score at 2 years. In the robotic milling group, there were no intraoperative femoral fractures, and a radiographically superior implant fit was obtained. Hand rasping had the potential to cause intraoperative femoral fractures, undersizing of the stem, unexpectedly higher vertical seating, and unexpected femoral anteversion causing inferior implant fit.
