Document Summary

Beware of fractures caused by an eversion/ er mechanism. Some may be a high ankle sprain, others may have a fracture. Fibula on talus is major support for medial side: stops talus from swinging out. Can be any or all of the structures in that slide. Eversion and external rotation of the ankle without deltoid. Ligament tear (cid:498)healthy(cid:499) ankle- would have no pain on palpation over deltoid. Positive squeeze test & er test on lower leg. Moi- usually in a skate/ ski boot. 10% (1%-18%) of all ankle sprains involve injury to the inferior tib/fib joint (syndesmosis: inversion= 85, eversion= 5, high ankle sprain= 10% Difficult to diagnose with prolonged recovery: up to 55 days, 2x grade 3 atfl. When the ankle is in neutral position the aitfl is oblique both to tibia and fibula. Interosseus membrane: fibers are also oblique to tibia and fibula.
