The short oblique fracture of the distal fibula occurring as a stage 2 supination-external rotation injury was investigated in respect to its effect on ankle stability in a series of cadaver dissections. Approximately 25 and 20 degrees of external rotational displacement of the distal fibula and talus, respectively, as well as approximately 1 mm of direct lateral talar shift were noted to be possible with this injury. This degree of rotational or lateral talar displacement was seen to result in tibiotalar joint incongruity. The deltoid ligament effectively prevented talar eversion but not the initial 2 to 3 mm of lateral talar displacement. Ankle stability in respect to medial talar shift was not compromised by removal of the medial malleolus.
在一系列尸体解剖中,对作为II度旋后-外旋损伤出现的腓骨远端短斜形骨折对踝关节稳定性的影响进行了研究。该损伤时,腓骨远端和距骨分别可能出现约25度和20度的外旋移位,以及距骨约1毫米的直接外侧移位。这种程度的旋转或距骨外侧移位会导致胫距关节不匹配。三角韧带可有效防止距骨外翻,但不能防止距骨最初2至3毫米的外侧移位。去除内踝不会损害踝关节相对于距骨内侧移位的稳定性。
