Description

The medial ankle sprains require a longer recovery time than that of a lateral ankle sprain. However, few studies have focused on the medial ankle sprains because of the low incidence. Therefore, a detailed injury mechanism is poorly understood. The purpose of this study was to clarify the foot and ankle bones movement when standing with ankle valgus. Thirteen males took part in this study. We scanned positional MRI in standing position. To scan MRI with ankle valgus, we had participants stood on three types of planes; flat plane, 10-degrees inclined plane, and 20 degrees inclined plane. We measured the vertical and medial foot arch bones position and hindfoot alignment view (HAV). One-way ANOVA with Bonferroni post-hoc was used to analyze the main effects of the plane angle. The main effect of the plane angle was observed for the medial navicular position (MNP), medial talus position (MTP), and HAV. Furthermore, the post-hoc test revealed that MNP, MTP, and HAV on 10-degrees plane and those on 20-degrees plane were larger than those on a flat plate. On the other hand, there were no differences between 10-degrees inclined plane and 20-degrees inclined plane in MNP, MTP, and HAV. Our results suggested that 20-degrees inclined plane restricted hindfoot valgus movement and medial movement of the navicular and talus.
