摘要

背景:人体骶髂关节(SIJ)的关节线几乎与重力方向平行,因此在体内暴露于压缩和剪切应力环境中。骶髂关节支持有效的双足行走。人们认为,意外或非生理性的反复撞击会造成关节错位,导致 SIJ 疼痛。在滑膜的 SIJ 前腔,关节表面呈现细微的不规则,可能会限制关节的运动:阐明在生理负荷下,SIJ 关节面如何影响运动阻力:方法:根据三名患者的计算机断层扫描数据创建 SIJ 表面模型,随后进行 3D 打印。使用定制装置测量了四个方向和三个组合位置的剪切阻力。此外,还通过卸载剪切力研究了 SIJ 的重新定位能力:结果:SIJ 下方向的剪切阻力最大。结论:结论:SIJ关节表面形态的设计可能是为了适应直立双足行走。因此,关节错位可能会增加半脱位的风险。

Experimental characterization of motion resistance of the sacroiliac joint.

Background: The human sacroiliac joint (SIJ) in vivo is exposed to compressive and shearing stress environment, given the joint lines are almost parallel to the direction of gravity. The SIJ supports efficient bipedal walking. Unexpected or unphysiological, repeated impacts are believed to cause joint misalignment and result in SIJ pain. In the anterior compartment of the SIJ being synovial, the articular surface presents fine irregularities, potentially restricting the motion of the joints.

Objective: To clarify how the SIJ articular surface affects the resistance of the motion under physiological loading.

Methods: SIJ surface models were created based on computed tomography data of three patients and subsequently 3D printed. Shear resistance was measured in four directions and three combined positions using a customized setup. In addition, repositionability of SIJs was investigated by unloading a shear force.

Results: Shear resistance of the SIJ was the highest in the inferior direction. It changed depending on the direction of the shear and the alignment position of the articular surface.

Conclusion: SIJ articular surface morphology is likely designed to accommodate upright bipedal walking. Joint misalignment may in consequence increase the risk of subluxation.
