Abstract

BACKGROUND

This study aimed to clarify the morphological characteristics of the Lisfranc ligament and the cuneiform 1-metatarsal 2&3 plantar ligament (CMPL).

METHODS

Forty legs from 20 cadavers were examined. Classification proceeded according to the number of fiber bundles in the Lisfranc ligament and the CMPL. Morphological features measured were fiber bundle length, width, thickness, and angle.

RESULTS

In Type I-a, the Lisfranc ligament and the CMPL were a single fiber bundle; in Type I-b, the Lisfranc ligament was a single fiber bundle, and the CMPL was two fiber bundles; in Type II-a, the Lisfranc ligament was a two fiber bundle, and the CMPL was a single fiber bundle; in Type II-b, the Lisfranc ligament and the CMPL were two fiber bundles; in Type III-a, the Lisfranc ligament was three fiber bundles, and the CMPL was a single fiber bundle; in Type III-b, the Lisfranc ligament was three fiber bundles, and the CMPL was two fiber bundles; in Type IV, the Lisfranc ligament and the CMPL could not be separated. Type I-a was seen in 37.5%, Type I-b in 10%, Type II-a in 30%, Type II-b in 7.5%, Type III-a in 7.5%, Type III-b in 2.5%, and Type IV in 5%. The Lisfranc ligament was significantly larger than the CMPL in total fiber bundle width, total fiber bundle thickness, and total fiber bundle angle.

CONCLUSION

The Lisfranc ligament had up to 3 fiber bundles and the CMPL had one or two fiber bundles; classifications were four types and two subgroups.

摘要

背景

本研究旨在阐明跖跗（Lisfranc）韧带和楔骨 1-跖骨 2&3 足底韧带（CMPL）的形态特征。

方法

对 20 具尸体的 40 条腿进行了检查。分类是根据跖跗（Lisfranc）韧带和 CMPL 的纤维束数量进行的。测量的形态特征包括纤维束长度、宽度、厚度和角度。

结果

在 I-a 型中，跖跗（Lisfranc）韧带和 CMPL 是单一纤维束；在 I-b 型中，跖跗（Lisfranc）韧带是单一纤维束，而 CMPL 是两条纤维束；在 II-a 型中，跖跗（Lisfranc）韧带是两条纤维束，而 CMPL 是单一纤维束；在 II-b 型中，跖跗（Lisfranc）韧带和 CMPL 是两条纤维束；在 III-a 型中，跖跗（Lisfranc）韧带是三条纤维束，而 CMPL 是单一纤维束；在 III-b 型中，跖跗（Lisfranc）韧带是三条纤维束，而 CMPL 是两条纤维束；在 IV 型中，跖跗（Lisfranc）韧带和 CMPL 无法分开。I-a 型占 37.5%，I-b 型占 10%，II-a 型占 30%，II-b 型占 7.5%，III-a 型占 7.5%，III-b 型占 2.5%，IV 型占 5%。跖跗（Lisfranc）韧带的总纤维束宽度、总纤维束厚度和总纤维束角度明显大于 CMPL。
