Document Summary

Might have felt a pop, couldn"t continue on. Pain on palpation on lateral side of lower leg/shank. Pain on palpation on anterior lateral ankle (malleoli) Responsible for of lost time in basketball and football. Stability comes from: shape of bones- mortise, joint capsule and ligaments, strength of muscles. Lateral malleolus: longer and more posterior than medial, this adds significant stability to lateral side- stopped by the handing down of the lateral malleolus. Talus: trochlear surface is wider anterior than posterior, has no muscles that attach to it, very extensive articular surface that slides, with dorsiflexion the wider anterior portion lies between the malleoli. Thin and weak anteriorly and posteriorly to allow movement. Strengthened medial and laterally by ligaments- thickenings- helps with side to side stability: some ligaments are part of capsule, some outside of capsule. Atfl (anterior talofibular ligament)- weakest of the 3 ligaments: strain increased with plantar flexion/ inversion, capsular.
