The authors performed a radiographic study of 136 patients with acute ligament sprains and 85 patients with chronic lateral ligament instability of the ankle. Varus angulation of the tibial plafond, varus angulation of the line passing both malleolar ends, and varus angulation of the medial malleolus were measured on the AP views, and dorsal angulation of the tibial plafond was measured on the lateral views. The varus angles of the tibial plafond, the line passing both malleolar ends, and the medial malleolus were larger as mean values in patients with chronic ligament instability than in the patients with acute ligament sprain. The varus tilt of the tibial plafond is more often seen in patients with chronic ligament instability of the ankle than in patients with acute ligament sprains.
作者对136例急性韧带扭伤患者和85例慢性踝关节外侧韧带不稳定患者进行了影像学研究。在前后位片上测量胫骨平台的内翻成角、通过双踝末端连线的内翻成角以及内踝的内翻成角，在侧位片上测量胫骨平台的背侧成角。慢性韧带不稳定患者的胫骨平台、通过双踝末端连线以及内踝的内翻角平均值大于急性韧带扭伤患者。与急性韧带扭伤患者相比，慢性踝关节韧带不稳定患者中更常出现胫骨平台的内翻倾斜。
