The Ankle and Foot Flashcards
movement possible at ankle
dorsiflexion/plantarflexion
inversion/eversion
abduction/adduction
toe flexion/extension
toe abduction/adduction
talocrural joint type and movement
synovial hinge joint
dorsiflexion and plantar flexion
function of the foot
base of support
adapt to uneven surfaces
shock absorber
propulsion
3 arches of the foot
medial arch
lateral arch
anterior transverse arch
where does the plantar vault contact the ground
head metatarsal I
head metatarsal V
calcaneal tuberosity
which bones is the medial arch made up of
calcaneus
talus
navicular
medial uniform
metatarsal I
which bones is the lateral arch made up of
calcaneus
cuboid
metatarsal V
which bones is the anterior transverse arch made of
5 heads of the metatarsals
how are arches stabilised?
shape of bones
strength of support
-short ligaments connecting adjacent bones
-long tissues spanning length of arch
-muscles pulling up on arch
parts of the gait cycle
heel strike
stance phase
heel off
toes off
where do movements of the hind foot occur?
subtalar joint (between calcaneus and talus)
where do movements of the forefoot occur?
mid tarsal joint (between talus and navicular/calcaneus and cuboid)
describe inversion and eversion
tri-planer
inversion: plantarflexion, adduction, supination
eversion: dorsiflexion, abduction, pronation
what movements occur at forefoot and hind foot in pronation movements (medial transfer of body weight)
forefoot: abduction, dorsiflexion, supination
hindfoot: adduction, plantarflexion, pronation
what movements occur at forefoot and hind foot in supination movements (lateral transfer of body weight)
forefoot: adduction, plantarflexion, pronation
hindfoot: abduction, dorsiflexion, supination
