Ankle Foot Flashcards
ankle/foot is blank to wrist
analagous
ankle is rigid when it is blank
supinated
bones in forefoot
metatarsals, phalanges
bones in midfoot
navicular, cuboid, 3 cuneiforms
bones in hindfoot
talus, calcaneus
vertical axis allows this motion in foot
abduction/adduction
longitudinal (a-p axis) allows for blank motion
inversion/eversion
inversion is aka
varus
eversion is aka
valgus
concurrent motions during pronation
dorsiflexion, eversion, abduction
concurrent motions during supination
plantar flexion, inversion, adduction
joint aka the mortise and between the tibia and fibula
proximal talocrural
the distal tibiofibular syndesmosis joint is like a blank because it allows some flexibility when the ankle blank
adjustable wrench, turns and twists some
distal talocrural has closed pack position in blank
dorsiflexion
anterior talus is blank than posterior talus
wider
distal talocrural joint has a larger SA on the blank side than the blank side
lateral, medial
distal talocrural joint has a blank talar surface in the sagittal plane
convex
talocrural joint is stabilized by
deltoid lig, lateral lig
neutral ankle roll would sprain blank most
cfl
plantar flexed ankle roll would sprain blank most
atfl
normal dorsiflexion at talocrural joint
20-35
normal plantar flexion at talocrural joint
30-50
normal talocrural adduction
7
normal talocrural abduction
10
normal talocrural inversion/eversion
5
inversion is aka
lateral tilt
eversion is aka
medial tilt
talocrural compression force during walking
4.5 times body weight
joint axes at talocrural joint is blank across all planes
oblique
talocrural joint is blank talus moving on blank mortise in open chain
convex, concave
dorsiflexion also creates blank because the talocrural joint runs out of SA on the blank side during open chain
abduction, medial
talocrural dorsiflexion close chained is blank mortise moving on blank talus
concave, convex
dorsiflexion creates blank during close chained
adduction
talus has a larger curvature radius on the blank side
lateral
fibular rotation is blank during dorsiflexion
medial
fibular rotation is blank during plantar flexion
lateral
as talus enters the mortise, the fibula glides blank
superior
proximal tib and fib do not have blank
degrees of freedom
fusing proximal tib and fib would have a significant impairment on blank motion unlike wrist
ankle
check rains to dorsiflexion
soleus, gastroc
check reins to plantar flexion
tib anterior, EHL, EDL
check reins to eversion
tib posterior, FDL, FHL (Tom Dick Harry)
check reins to inversion
fibularis longus/brevis
subtalar joint has blank articulations
3
anterior/middle facets of calcaneus are blank
concave
posterior facet of calcaneus is blank
convex
3 subtalar articulations are separated by the blank
sinus tarsi
subtalar joint job is the maintain blank
foot contact with ground
subtalar joint ligament that limits eversion
interosseous talocalcaneal
subtalar joint ligament that limits inversion
lateral talocalcaneal ligament, cervical ligament
other lig of subtalar joint
posterior talocalcaneal lig
subtalar joint has blank motion on a blank axis
triplanar, single
subtalar joint has blank moving on the blank
calcaneus, talus
motions of subtalar joint
supination/pronation with components
in closed chain, subtalar calcaneuswill not blank or blank which causes blank to move instead
abd/add, df/pf, talus
closed chain supination at subtalar joint
calcaneal inversion, talar abduction & dorsiflexion
closed chain pronation at subtalar joint
calcaneal eversion, talar adduction & plantar flexion
closed pack position of subtalar joint
supination
posterior subtalar facet is blank on blank
concave talus, convex calcaneus
anterior/middle subtalar facet is blank on blank
convex talus, concave calcaneus
why subtalar and talocrural joints are both triplanar but have different components
-subtalar is oblique axis across planes
-ROM ratio: 4:4:1
abd/add:ev/iv:pf/df
most people have a blank at subtalar joint
varus moment
most people have blank times more supination compared to pronation
2
subtalar joint is like a blank between the leg and foot
