PURPOSE

This study aimed to test the hypothesis that routine MRI ankle can be used to evaluate dimensions and correlations between dimensions of single and double fascicular variants of the ATFL and the CFL.

METHODS

We reviewed ankle MRIs for 251 patients. Differences between the length, thickness, width, and length of the bony attachments were evaluated twice. P < .05 was considered as significant.

RESULTS

For the ATFL, we observed a negative correlation between thickness and width, with a positive correlation between thickness and length (p < 0.001). The average values for the ATFL were thickness, 2.2 ± 0.05 mm; length, 21.5 ± 0.5 mm; and width, 7.6 ± 0.6 mm. The average values for the CFL were thickness, 2.1 ± 0.04 mm; length, 27.5 ± 0.5 mm; and width, 5.6 ± 0.3 mm. A negative correlation was found between length and width for the CFL (p < 0.001).

CONCLUSIONS

Routine MRI showed that most dimensions of the ATFL and CFL correlate with each other, which should be considered when planning new reconstruction techniques and developing a virtual biomechanical model of the human foot.

目的

本研究旨在验证以下假设，即踝关节常规磁共振成像（MRI）可用于评估距腓前韧带（ATFL）和跟腓韧带（CFL）单束和双束变异的尺寸以及各尺寸之间的相关性。

方法

我们回顾了251例患者的踝关节MRI图像。对韧带长度、厚度、宽度以及骨附着点长度的差异进行了两次评估。P < 0.05被视为具有统计学意义。

结果

对于ATFL，我们观察到厚度与宽度呈负相关，厚度与长度呈正相关（p < 0.001）。ATFL的平均值为：厚度2.2±0.05毫米；长度21.5±0.5毫米；宽度7.6±0.6毫米。CFL的平均值为：厚度2.1±0.04毫米；长度27.5±0.5毫米；宽度5.6±0.3毫米。CFL的长度与宽度呈负相关（p < 0.001）。
