We evaluate the inter- and intraobserver variability of a telemanipulated femur fracture reduction system using a joystick device. Five examiners performed virtual reduction of 3D femur fracture models on two separate occasions. We assessed the inter- and intraobserver variability for the final alignment and reduction. The average difference between testing rounds was only 0.3 mm for overall displacement and 0.5° for overall rotation. There was an average time reduction between rounds of 11.7 s. The mean differences in overall displacement between examiners ranged between 0.2 and 0.9 mm; between 0.2° and 3.2° for overall rotation; and between 9 and 82 s for time to reduction. The time required to complete the reduction did not have a significant effect on the overall displacement or rotation of the final model. Telemanipulated fracture reduction is a reliable and reproducible technique, which does not require extensive training.
我们使用操纵杆设备评估了远程操作的股骨骨折复位系统在观察者间和观察者内的变异性。五名检查人员在两个不同的场合对3D股骨骨折模型进行了虚拟复位。我们评估了观察者间和观察者内最终对线和复位的变异性。测试轮次之间的平均差异为：整体位移仅0.3毫米，整体旋转为0.5°。两轮之间平均时间减少了11.7秒。检查人员之间整体位移的平均差异在0.2至0.9毫米之间；整体旋转在0.2°至3.2°之间；复位时间在9至82秒之间。完成复位所需的时间对最终模型的整体位移或旋转没有显著影响。远程操作骨折复位是一种可靠且可重复的技术，不需要大量培训。
