What are the normal radiographic measurements at the ankle (measurements 1cm proximal to plafond)?

踝关节正常的X线测量值是多少（距穹隆 1 厘米处）？

AP view:

- Medial clear space = <4mm (less than or equal to the superior clear space)

- Tibiofibular clear space = <6mm

- Tibiofibular overlap = >6mm

前后位像：

- 内侧间隙 = <4 毫米（小于或等于上方间隙）

- 胫腓间隙 = <6 毫米

- 胫腓重叠 = >6 毫米

Oblique/mortise view

- Tibiofibular clear space = <6mm

- Tibiofibular overlap = >1mm

- Talocrural angle = 83°+/- 4°or within 5°of the contralateral side

斜/踝穴位

- 胫腓间隙 = <6 毫米

- 胫腓重叠 = >1 毫米

- 胫距角 = 83°+/- 4° 或对侧 5° 以内。
