The purpose of this study was to quantify in vivo the three-dimensional motion patterns of the sacroiliac joint during passive manipulations as the opinions about the extent of motion of this joint are varied. 12 sacroiliac joints of 6 patients with clinically and radiologically normal joints were investigated. All patients were treated with an external fixator for diagnostic purposes of low back pain unrelated of this study. The motion of the sacroiliac joint was measured continuously with a three-dimensional goniometric system, which was mounted at the end of Schanz screws implanted in S1 and the ilium. All measurements showed relatively small rotation angles around the three main axis to the body between the ilium and the sacrum (< 2 degrees) and very small translations between the screw entry points into the bones (< 1 mm). The maximum rotation angle in the sagittal plane was 1.3 degrees on the right joint and 1.6 degrees on the left joint for flexion plus extension. It is questionable whether this motion can be quantified during manual manipulation. Extension of the hip always produced the largest motion in the sacroiliac joint.
本研究的目的是在体内量化骶髂关节在被动手法操作过程中的三维运动模式，因为关于该关节运动程度的观点各不相同。对6例临床和放射学检查关节正常的患者的12个骶髂关节进行了研究。所有患者均使用外固定器进行治疗，目的是诊断与本研究无关的下腰痛。使用三维测角系统连续测量骶髂关节的运动，该系统安装在植入S1和髂骨的斯氏针末端。所有测量结果显示，髂骨和骶骨之间围绕身体三个主轴的旋转角度相对较小（<2度），螺钉进入骨骼的点之间的平移非常小（<1毫米）。右侧关节在矢状面的最大旋转角度为1.3度，左侧关节为1.6度，用于屈伸。这种运动在手法操作过程中是否能够被量化值得怀疑。髋关节伸展总是在骶髂关节产生最大的运动。
