The isolated spiral fracture of the fibula is the most common ankle fracture (supination-lateralrotation stage II).
腓骨的单纯螺旋骨折在此类骨折中最为常见（旋后外旋II度）。

The presence of a medial malleolar fracture (FIG. 4d), establishes this to be a complete injury, a supination-lateralrotation stage IV.
内踝骨折的出现(图。4d)表明这是一个完全损伤，即旋后外旋IV度。
