Document Summary

Pronation- allows the foot to be flexible/adaptable. Supination- allows the foot to be rigid. Movement of the foot with respect to eh leg is the sum of motions of the. Talocrural joint, mid- tarsal joint, forefoot, mtp and ip joints. Adduction and abduction- transverse plane (like rotation) Ex: limited df at ankle - excess flexion at hip/knee. Because of the orientation of axes, no movement of the foot is in one plane. Convex talar head (medial and lateral domes are not equal) Concave mortise of distal tibia and fibula. Rom: sagittal plane dominates, axis through malleoli (responsible for pf, Df so talocrural joint is where you look when patient presents with pf/df problems) Anterior talofibular ligament (more commonly sprained)- resists inv with. Calcaneofibular ligament- resists inversion (test with inversion stress) Posterior talofibular- resists inv with df (test with posterior drawer) Deltoid (medial ligaments)-resists eversion (helps maintain medial arch of foot) Joint surfaces: varies from person to person.
