這位女士5天前扭傷左踝，
左踝外側腫痛，無法踩地。
有骨折嗎 ??

讓我們放大來看標示處，
也就是理學檢查上最明顯的痛點。
似乎不是很平整和連續喔。
The marked sites were the most painful points.
The cortical margins are not smooth.
縱向掃描看出腓骨處的不連續
Longitudinal scan showed discontinuous cortical surface on distal fibular bone
橫向掃描也同樣發現不連續性和微小碎骨
Transverse scan showed the discontinuity and tiny fragments.
脛骨的連續平滑面可供參考
We use the smooth and continuous cortical surface of tibial bone for comparison.
