85%以上患者踝關節受傷後接受影像學檢查無法顯示出骨折,陽性率不到15%。因此,Stiell等人於1992年提出了一個針對踝關節損傷初步鑒別診斷標準-----渥太華關節規則(Ottawa ankle rules),將踝關節損傷分為踝部及中足部(足弓),通過病史及理學檢查判斷患者是否需要進一步X-ray檢查
踝部x-ray檢查陽性指徵:
- 脛骨遠端近踝頂端後側緣6cm範圍內或內踝頂端的骨頭有壓痛
(Bone tenderness along the distal 6 cm of the posterior edge of the tibia or tip of the medial malleolus)
- 腓骨遠端近踝頂端後側緣6cm範圍內或外踝頂端的骨頭有壓痛
(Bone tenderness along the distal 6 cm of the posterior edge of the fibula or tip of the lateral malleolus)
- 受傷後即刻或在急診科時患肢無法支撐身體重量(走4步)
(An inability to bear weight both immediately and in the emergency department for four steps)
