Present techniques of assessing rotational alignment in bone are limited to gross anatomical and radiographic observations made at a single point in time. Because of these quantitative limitations, this paper describes a radiographic technique devised to give precise information elucidating the direction, magnitude and site of rotational change. This technique is based on the radiographic monitoring of a positional change, in vivo, of biologically inert marker pins in the long bones. Animal investigations have demonstrated the validity of the in vivo angular assessments and have also shown morphologic and biomechanical compatibility. Laboratory experiments simulating an in vivo deflection were performed with a correlation of 0.999 found between the calculated angles and those measured in vitro.
目前评估骨骼旋转对线的技术仅限于在单一时间点进行的大体解剖和影像学观察。由于这些定量限制，本文描述了一种影像学技术，旨在提供精确信息，阐明旋转变化的方向、大小和部位。该技术基于对长骨中生物惰性标记针在体内位置变化的影像学监测。动物研究已证明体内角度评估的有效性，并且还显示出形态学和生物力学的兼容性。进行了模拟体内偏转的实验室实验，计算角度与体外测量角度之间的相关性为0.999。
