Abstract

Background

This study aimed to evaluate the shape of the retromalleolar groove of the tibialis posterior tendon (TPT) using computed tomography (CT).

Methods

CT images of patients with foot or ankle pathologies were retrospectively reviewed. The morphology of the retromalleolar groove of the TPT was assessed at two different levels: the ankle joint and 10 mm above the ankle joint. The groove shape was classified into three types; concave, flat, or irregular. In cases with concave grooves, the width and depth of the grooves were measured.

Results

Of the 116 ankles from 116 subjects included in this study, 80.2 % showed a shallow concave shape (mean depth, 1.6 mm) at the two scan levels. The shape and width of the groove differed significantly by gender, although there was no significant difference in the groove depth.

Conclusion

Approximately 80% showed a shallow concave groove of the TPT. The groove characteristics differed by gender, although there was no significant difference in the groove depth.

Level of evidence

Cross-sectional cohort study; Level of evidence, Ⅳ

通过轴向计算机断层扫描评估无胫骨后肌腱（TPT）病变患者的胫骨后肌腱（TPT）后沟形态。

背景：本研究旨在使用计算机断层扫描（CT）评估胫骨后肌腱（TPT）的后腓侧沟形状：本研究旨在使用计算机断层扫描（CT）评估胫骨后肌腱（TPT）后腓侧沟的形状：方法：对足部或踝部病变患者的 CT 图像进行回顾性审查。在踝关节和踝关节上方 10 毫米处的两个不同水平评估了胫骨后肌腱后侧沟的形态。凹槽形状分为三种类型：凹形、扁平形或不规则形。在凹陷沟槽的情况下，测量沟槽的宽度和深度：结果：在 116 名受试者的 116 个脚踝中，80.2% 在两个扫描层面上显示出浅凹形（平均深度为 1.6 毫米）。尽管凹槽深度没有明显差异，但凹槽的形状和宽度在性别上存在显著差异：结论：约 80% 的 TPT 显示浅凹槽。结论：约 80% 的 TPT 显示浅凹槽，不同性别的凹槽特征不同，但凹槽深度无明显差异：证据等级：横断面队列研究；证据等级Ⅳ。

期刊介绍： Foot and Ankle Surgery is essential reading for everyone interested in the foot and ankle and its disorders. The approach is broad and includes all aspects of the subject from basic science to clinical management. Problems of both children and adults are included, as is trauma and chronic disease. Foot and Ankle Surgery is the official journal of European Foot and Ankle Society. The aims of this journal are to promote the art and science of ankle and foot surgery, to publish peer-reviewed research articles, to provide regular reviews by acknowledged experts on common problems, and to provide a forum for discussion with letters to the Editors. Reviews of books are also published. Papers are invited for possible publication in Foot and Ankle Surgery on the understanding that the material has not been published elsewhere or accepted for publication in another journal and does not infringe prior copyright.
