A three-dimensional stereophotogrammetric method is described for measuring the mobility of the sacroiliac joint, which was based on preliminary two-dimensional in vitro experiments. The investigations were carried out with intraosseous markers in 24 healthy volunteer male (15) and female (9) subjects having an age range of 20 to 50 years. Considerable intra- and inter-individual variability was found for both the measurements of rotation and translation. The position and direction of the movement axes showed wide variations, but a basic pattern could always be recognized. The average values for rotation and translation were low, being 1.8 degrees / 0.7 mm for the males and 1.9 degrees / 0.9 mm for the females. No statistically significant differences could be demonstrated with respect to either sex or age. On the basis of the measurement results, it is postulated that there is pathological sacroiliac joint movement when rotation is more than 6 degrees and translation more than 2 mm. This increased mobility seems to be of greater clinical significance than reduced mobility.
本文描述了一种基于初步二维体外实验的三维立体摄影测量法，用于测量骶髂关节的活动度。研究在24名年龄在20至50岁之间的健康志愿者身上进行，其中男性15名，女性9名，使用骨内标记物。在旋转和位移测量中均发现了显著的个体内和个体间差异。运动轴的位置和方向变化很大，但总能识别出基本模式。旋转和位移的平均值较低，男性为1.8度/0.7毫米，女性为1.9度/0.9毫米。在性别或年龄方面未发现统计学上的显著差异。根据测量结果推测，当旋转超过6度且位移超过2毫米时，存在病理性骶髂关节活动。这种增加的活动度似乎比活动度降低具有更大的临床意义。
