背景：腕管形态在腕管综合征的病因和治疗中起着至关重要的作用。本研究的目的是观察腕弓宽度变窄后腕管的形态学变化。据推测，腕弓宽度缩小会导致在增加的高度和面积的carpalarch.Methods：8具尸体的手腕弓宽度缩小了一个自定义的设备和横截面超声图像被收购。当腕弓宽度变窄时，量化腕弓高度和面积。相关和回归分析进行了腕弓的高度和面积相对于腕弓wide.Findings：腕管变得更凸的腕弓宽度缩小。最初的腕弓宽度、高度和面积分别为25.7（SD 1.9）mm、4.1（SD 0.6）mm和68.5（SD 14.0）mm（2）。腕弓高度和面积与腕弓宽度呈负相关，相关系数分别为-0.974（SD 0.018）和-0.925（SD 0.034）。线性回归分析显示，腕弓宽度每缩小1 mm，腕弓高度（SD 0.14）mm，腕弓高度（SD 4.0（SD 2.2）mm（2）在腕弓区。解释：这项研究表明，腕弓宽度缩小导致腕弓高度和面积增加，减少正中神经机械损伤和缓解腕管综合征相关症状的潜在机制。(C)2013爱思唯尔有限公司保留所有权利。
Background: Carpal tunnel morphology plays an essential role in the etiology and treatment of carpal tunnel syndrome. The purpose of this study was to observe the morphological changes of the carpal tunnel as a result of carpal arch width narrowing. It was hypothesized that carpal arch width narrowing would result in increased height and area of the carpal arch.Methods: The carpal arch width of eight cadaveric hands was narrowed by a custom apparatus and cross-sectional ultrasound images were acquired. The carpal arch height and area were quantified as the carpal arch width was narrowed. Correlation and regression analyses were performed for the carpal arch height and area with respect to the carpal arch width.Findings: The carpal tunnel became more convex as the carpal arch width was narrowed. The initial carpal arch width, height, and area were 25.7 (SD 1.9) mm, 4.1 (SD 0.6) mm, and 68.5 (SD 14.0) mm(2), respectively. The carpal arch height and area negatively correlated with the carpal arch width, with correlation coefficients of -0.974 (SD 0.018) and -0.925 (SD 0.034), respectively. Linear regression analyses showed a 1 mm narrowing of the carpal arch width resulted in proportional increases of 0.40 (SD 0.14) mm in the carpal arch height and 4.0 (SD 2.2) mm(2) in the carpal arch area.Interpretation: This study demonstrates that carpal arch width narrowing leads to increased carpal arch height and area, a potential mechanism to reduce the mechanical insult to the median nerve and relieve symptoms associated with carpal tunnel syndrome.
