Document Summary

Generally in this order, but it doesn"t have to happen in this order: High ankle sprains and lower leg injuries: part 1: deltoid ligament, anterior inferior tibiofibular ligament, fracture of distal end of fibula and tibia. When assessing area, hit all of the landmarks. Fibula on talus is major support for medial side. Relatively good stability without deltoid: still have fibula hanging down. Very poor stability with fractured fibula: fibula is holding the joint together. Can be any or all of the 3 structures. Eversion and external rotation of ankle without deltoid ligament tear. If there is pain fractured fibula: when you externally rotate the foot, you are prying the two bones apart. Hockey player turns to play the puck and falls awkwardly. Foot externally rotates in a dorsiflexed position. ~10% (1-18%) of all ankle sprains involve injury to the inferior tib/fib joint (syndesmosis) Difficult to diagnose with prolonged recovery: not great tests to diagnose by imaging.
