From: Tips and Tricks in surgical reduction of the posterior column of AO/OTA C3 pilon fractures
Anatomical | No medial or lateral displacement of the medial and lateral malleoli No angulation Not more than 1 mm longitudinal displacement of the medial and lateral malleoli Not more than 2 mm proximal displacement of a large posterior fragment No displacement of the talus |
Fair | No medial or lateral displacement of the medial and lateral malleoli No angulation 2–5 mm posterior displacement of the lateral malleolus 2–5 mm proximal displacement of a large posterior fragment No displacement of the talus |
Poor | Any medial or lateral displacement of the medial and lateral malleoli More than 5 mm posterior displacement of the lateral malleolus or more than 5 mm displacement of the posterior malleolus Any residual displacement of the talus |
