Document Summary

Important in absorbing shock and acting as springboards during locomotion: resiliency of arches adds to foot"s ability to adapt to changing surfaces as well as shock we encounter during walking. 3 arches in foot: arches of foot maintained by 5 things (4 strong plantar ligaments and an aponeurosis, 2 longitudinal, 1 transverse, passive factors. Strong ligaments and plantar aponeurosis: dynamic factors. Tendons traveling from leg: tibialis posterior, tibialis anterior, peroneus longus, flexor. Cuboid; base 2-4 metatarsals: pa, da, two slips of tendon creates a canal for tendon of peroneus longus, short plantar ligament: just medial and slightly deeper to long plantar ligament. Cuboid: pa, da, aka plantar calcaneocuboid ligament, spring ligament: Medial and a little up side of foot from short plantar ligament. Navicular (just under navicular tuberosity and tendon of tibialis posterior: pa, da, aka plantar calcaneonavicular ligament, play important role in maintaining bones close to one another and maintaining arches.
