Foot and ankle
Radiography (Mortise (15° internal rotation))
|Line between the two malleolus. The talocrural angle is the angle between this line and the tibial plafond.|
|A second talocrural angle exists and it is formed by a line between the two malleolus and a perpendicular line to tibial plafond. The normal value for this angle is 79-87°.|
|The difference between right and left talocrural angle must be <5°.|
|Some authors advocate that the difference must be <3°.|
