Document Summary

Lateral sprains inversion mechanism lateral ligametns: atf (anterior talofibullar), cf (calcaneofibular), ptf (posterior talofibular) lateral ligs limit inversion, need 3 because you can invert in several different positions (plantar, doris), can sprain it throughout diff rom. Sprain atf: plantar flexion + inversion most common ankle sprain. Sprain ptf: dorsiflexion + inversion not as often, but still possible. Att (anterior tibiotalar), tn (tibionavicular), tc (tibiocalcaneal), ptt (posterior tibilotalar) Att and atf hold talus so it doesn"t go too far forward so it can still go back properly for dorsi. If talus slides too far out of mortis without going back in, it results in pinching in the long run result of atf/att damage. Weak eccentrically: so strength of everters, counter strength that causes you to go into inversion, everters have to contract form a lengthened position , ecc strength of muscles to prevent injury is important in preventing ankle sprain.
