The purpose of this study was to investigate the morphological and mechanical properties of the transverse carpal ligament (TCL) in patients with carpal tunnel syndrome (CTS). Thickness and stiffness of the TCL in eight female CTS patients and eight female control subjects were examined using ultrasound imaging modalities. CTS patients had a 30.9% thicker TCL than control subjects. There was no overall difference in TCL stiffness between the two groups, but the radial TCL region was significantly stiffer than the ulnar region within the CTS group and such a regional difference was not found for the controls. The increased thickness and localized stiffness of the TCL for CTS patients may contribute to CTS symptoms due to reduction in carpal tunnel space and compliance. Advancements in ultrasound technology provide a means of understanding CTS mechanisms and quantifying the morphological and mechanical properties of the TCL .
本研究的目的是调查腕管综合征（CTS）患者腕横韧带（TCL）的形态学和力学特性。使用超声成像方式检查了8名女性CTS患者和8名女性对照受试者的TCL厚度和刚度。CTS患者的TCL比对照受试者厚30.9%。两组之间TCL刚度没有总体差异，但CTS组内桡侧TCL区域比尺侧区域明显更硬，而对照组未发现这种区域差异。CTS患者TCL厚度增加和局部刚度增加可能由于腕管空间和顺应性降低而导致CTS症状。超声技术的进步为理解CTS机制以及量化TCL的形态学和力学特性提供了一种手段。
