机器人与机器学习每日新闻-肌肉骨骼疾病和条件的新研究-的新闻记者-工作人员新闻编辑-骨关节炎是一篇报道的主题。根据NewsRx记者来自英国伦敦的新闻报道，Re Search指出，“全髋关节置换术(THA)的术前规划涉及利用X线片或先进的成像方式，包括计算机化到运动图(CT)扫描，以精确预测植入物的大小和位置。他的研究旨在比较初级THA中三维(3D)和二维(2D)PR电子手术规划在关键外科指标方面的差异，包括恢复水平和垂直旋转中心(COR)、组合D偏移和腿长。我们的新闻编辑从伦敦大学学院(UCL)医院NHS基金会信托基金的研究中获得了一句话，"这项研究包括60名因有症状的髋关节骨性关节炎而接受初级THA的患者。随机分为EITHER机器人臂辅助全髋关节置换术和常规全髋关节置换术,采用机器人软件进行数字二维模板和三维规划,术前CT扫描图像进行测量,评价模板方法的准确性。敏感性分析探讨了超晚期或内侧骨关节炎患者2D和3D计划的差异，与2D模板相比，3D模板与水平COR的内中化程度较低(-1.2 vs-0.2 m，P=0.002)，相对于对侧垂直COR的恢复更准确(1.63 vs 0.3 mm，P<0.001)。3D模板在计划恢复腿长方面优于(+0.23 vs-0.74 mm,P=0.019)。敏感性分析表明,在内侧骨关节炎患者中,3D模板减少了横带COR的内侧化和偏移减少。相反,在超外侧骨关节炎患者中,3D模板减少了水平COR的外侧化和偏移增加。3D计划显示出对柄、髋臼杯大小和颈部角度的良好可重复性，而2D计划导致柄和杯大小更小。我们的发现表明，使用3D计划修复天然关节力学的准确性更高。
Abstract
By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News – New research on Musculoskeletal Diseas es and Conditions - Osteoarthritis is the subject of a report. According to news reporting originating from London, United Kingdom, by NewsRx correspondents, re search stated, “Pre-operative planning in total hip arthroplasty (THA), involves utilizing radiographs or advanced imaging modalities, including computerized to mography (CT) scans, for precise prediction of implant sizing and positioning. T his study aimed to compare Three-Dimensional (3D) versus Two-Dimensional (2D) pr e-operative planning in primary THA with respect to key surgical metrics, includ ing restoration of the horizontal and vertical Center of Rotation (COR), combine d offset, and leg length.” Our news editors obtained a quote from the research from University College Lond on (UCL) Hospitals NHS Foundation Trust, “This study included 60 patients underg oing primary THA for symptomatic hip osteoarthritis, randomly allocated to eithe r robotic-arm-assisted or conventional THA. Digital 2D templating and 3D plannin g using the robotic software were performed for all patients. All measurements t o evaluate the accuracy of templating methods were conducted on the pre-operativ e CT scanogram, using the contralateral hip as a reference. Sensitivity analyses explored differences between 2D and 3D planning in patients who had supero-late ral or medial osteoarthritis patterns. Compared to 2D templating, 3D templating was associated with less medialization of the horizontal COR (-1.2 versus -0.2 m m, P = 0.002) and more accurate restoration of the vertical COR (1.63 versus 0.3 mm, P<0.001) with respect to the contralateral side. Furt hermore, 3D templating was superior for planned restoration of leg length (+0.23 versus -0.74 mm, P = 0.019). Sensitivity analyses demonstrated that in patients who had medial osteoarthritis, 3D planning resulted in less medialization of ho rizontal COR and less offset reduction. Conversely, in patients who had supero-l ateral osteoarthritis, there was less lateralization of horizontal COR and less offset increase using 3D planning. Additionally, 3D planning showed superior rep roducibility for stem, acetabular cup sizes, and neck angle, while 2D planning o ften led to smaller stem and cup sizes. Our findings indicated higher accuracy i n the planned restoration of native joint mechanics using 3D planning.”
