Document Summary

Consists of: 26 bones, 14 phalanges, 5 metatarsals, 7 tarsals, the tibia and fibula. Ankle inversion and eversion: more inversion range than eversion. Talus pushing up against the tibia prevents too much eversion. Medial ligament ( deltoid which prevents eversion) is much stronger than lateral ligaments (which prevent inversion) 80% of sprains are inversion: occur at the subtalar joint (between talus and calcaneus) Calcaneus moves medially = inversion, laterally = eversion. Pronation and supination are combined movements here: supinated foot pes cavus high arch, pronated foot pes planus flat foot, inverting muscles: tibialis anterior, tibialis posterior, everting muscles: peroneus longus, peroneus brevis, peroneus tertius. Sinus tarsi: a depression between the calcaneus and talus where. *see slides for bones of the foot* swelling accumulates in inversion sprains: on lateral side of foot (under lateral malleolus, found here: anterior talofibular ligament, fat pad, extensor digitorum brevis. Medial tubercle: where plantar fascia originates from on the calcaneus.
