摘要

背景:关于腕管形态的文献很多。尽管如此,有关腕管形态的报道并不稳定,而且大多数研究并未尝试将研究结果与尸体测量结果进行关联。本研究的目的是进行形态分析,确定腕管的形状和平均尺寸,确定腕管最窄区域的水平,并建立一套可作为腕管松解参考的数值:方法:解剖 20 只新鲜尸体手的腕管,制作丙烯酸模型,并使用工业计算机断层扫描进行测量:结果:在 20 个模型中,19 个的形状像椭圆形圆柱体,沿长度方向的测量值变化不大。不同模型腕管最窄部分的位置差异很大,腕管顶端的长度从 21.26 毫米到 29.86 毫米不等:结论:腕管最常见的形状是椭圆形圆柱体。结论:腕管最常见的形状是椭圆形圆柱体。由于腕管最窄区域的位置难以预测,因此腕管松解必须持续到腕管顶端的所有延伸部分。我们建议,腕管松解的远端距离腕掌远端皱襞应很少超过 30 毫米,在大多数情况下,这相当于腕桡骨的中部。

Carpal Tunnel Anthropometrics Using Acrylic Casts: A Cadaveric Study With Implications for Carpal Tunnel Release.

Background: Abundant literature exists on the morphology of the carpal tunnel. Despite this, the shape of the carpal tunnel has been reported erratically, and most studies did not attempt to correlate findings with measurements taken from cadavers. The objective of this study was to perform a morphological analysis, determine the shape and mean dimensions of the carpal tunnel, determine the level of the narrowest area of the tunnel, and establish a set of values capable of serving as a reference for carpal tunnel release.

Methods: The carpal tunnels of 20 fresh cadaveric hands were dissected, and acrylic casts were created and measured using industrial computed tomography.

Results: Of the 20 casts, 19 were shaped like elliptic cylinders, with little variation in their measurements along the length. The location of the narrowest section of the carpal tunnel is very different among casts, and the length of the roof of the carpal tunnel ranged from 21.26 to 29.86 mm.

Conclusions: The most common shape of the carpal tunnel is an elliptic cylinder. Because of the unpredictability of the location of the narrowest area of the carpal tunnel, carpal tunnel release must continue through all extension of its roof. We advise that the release should rarely be extended distally more than 30 mm from the distal palmar wrist crease, which corresponds, in most cases, to the middle of the pisiform.
