Ligamentous instability of the ankle joint can be confirmed by radiographs taken in two planes. The place of the anteroposterior varus stress view is established, but the lateral view which shows anterior subluxation of the talus is frequently omitted. The anatomical significance of the two stress views has been determined by dividing different components of the lateral ligament of 20 cadaveric ankles and noting the subluxation that resulted from these procedures. A clinical assessment was then made of 54 ankles (46 patients) with radiological evidence of instability when subjected to varus and anterior stress. Anterior subluxation was found to be considerably more common than varus tilt, and it is therefore suggested that the lateral stress view should be an essential part of the investigation of the unstable ankle.
踝关节的韧带不稳定可通过两个平面的X线片来确诊。前后位内翻应力位片的位置已确定，但显示距骨前半脱位的侧位片常常被遗漏。通过对20个尸体踝关节外侧韧带的不同组成部分进行划分，并记录这些操作导致的半脱位情况，已确定了这两种应力位片的解剖学意义。随后，对54个踝关节（46例患者）进行了临床评估，这些踝关节在接受内翻和前向应力时具有影像学不稳定证据。发现前半脱位比内翻倾斜更为常见，因此建议外侧应力位片应成为不稳定踝关节检查的重要组成部分。
