Closed fracture reduction can be a challenging task. Robot-assisted reduction of the femur is a newly developed technique that could minimize potential complications and pitfalls associated with fracture reduction and fixation. We conducted an experimental study using 11 human cadaver femora with intact soft tissues. We compared robot-assisted fracture reduction using 3D visualization with manual reduction, using 2D fluoroscopy. The main outcome measure was the accuracy of reduction. The manual reductions were done by an experienced orthopedic trauma surgeon, whereas the robot-assisted reductions were done by surgeons of different experience. The robot-assisted group showed significantly less postreduction malalignment (p < 0.05) for internal/external rotation (2.9 degrees vs. 8.4 degrees ) and for varus/valgus alignment (1.1 degrees vs. 2.5 degrees ). However, the reduction time was significantly (p < 0.01) longer (6:14 min vs. 2:16 min). The higher precision associated with robot-assisted fracture reduction makes this technique attractive and further research and development worthwhile. In particular, less experienced surgeons may benefit from this new technique.
闭合性骨折复位是一项具有挑战性的任务。机器人辅助股骨复位是一种新开发的技术，可以最大限度地减少与骨折复位和固定相关的潜在并发症和陷阱。我们使用 11 个人体尸体股骨进行了一项实验研究，这些股骨的软组织完整。我们比较了使用三维可视化的机器人辅助骨折复位与使用二维透视的手动复位。主要的观察指标是复位的准确性。手动复位由经验丰富的创伤骨科医生完成，而机器人辅助复位由经验不同的外科医生完成。机器人辅助组的内/外旋转（2.9 度对 8.4 度）和内翻/外翻（1.1 度对 2.5 度）的复位后对线不良明显减少（p < 0.05）。然而，复位时间明显（p < 0.01）延长（6:14 分钟对 2:16 分钟）。机器人辅助骨折复位的更高精度使得这项技术具有吸引力，值得进一步的研究和开发。特别是，经验较少的外科医生可能受益于这项新技术。
