Document Summary
30 muscles: functions, stability, mobility: weight bearing activity and act as rigid level for locomotion. Talocrural joint designed for stability conforms to uneven surfaces. Subtalar joint and midtarsal joint designed to transition mobile to stable: absorb shock, convert transverse torque from lower extremity. Allow le to rotate, but keep foot on ground. Bones: fibula, tibia, many muscles act on foot originating from anterolateral and posterior borders, anteromedial border only has thin layer of connective tissue on it. More likely to have fractures than superior/proximal portion: talus. Equivalent to entire proximal row of carpals. Cannot heal because it has no blood supply to it. Superior surface is wider anterior than it is posterior: allows for foot to be able to rock in abduction and adduction when foot is plantarflexed. 4 parts: trochlea, body, neck, head, calcaneus convex top portion of talus. 3 articular facets with talus: anterior, medial, posterior.
