Ankle & Foot Flashcards
plantarflexion=
50
dorsiflexion =
20s
supination =
45-60
pronation =
15-30
resting position of tibiofibular joint
plantar flexion
closed packed of tibiofibular joint and talocrural joint
max dorsiflexion
what is the inferior tibiofibular joint supported by
anterior tibiofibular
posterior tibiofibular
inferior transverse ligaments
interosseous ligaments
resting position of talocrural joints
10 degrees of P.F
midway between max inversion and max eversion
capsular pattern of restriction for talocrural
plantarflexion –> dorsiflexion
what is the medial (deltoid) ligament split into
tibionavicular
tibiocalcaneal
posterior tibiotalar
anterior tibiotalar is deep to other 3
what does the anterior tibiotalar ligament resist
lateral translation and lateral rotation of talus
on lateral aspect what are the main ligaments
anterior talofibular (stability against excessive inversion of talus)
posterior talofibular lig (resists D.F, adduction, medial rotation, medial translation of talus
calcaneofibular (stability against inversion)
closed packed position of subtalar
supination
3 degrees of freedom
medial rotation of leg causes a ____ movement of calcaneus
valgus (outward)
during closed chain, where does the talus move
up - to help the foot and leg adapt to terrain and to stress applied to foot
in open chain the talus is fixed
what does the medial longitudinal arch consist of
calcaneal tuberosity
talus
navicular
3 cuneiforms
1,2,3 metatarsal bones
what is te medisl longitudinal arch maintained by
tib ant\tib post
flexor digitorum longus
flexor hallucis longus
abductor hallucis
flexor digitorum brevis
plantar fascia
plantar calcaneonavicular ligament
what does the lateral longitudinal arch consist of
calcaneus
cuboid
4,5, metatarsal bones
what does the transverse arch consist of
navicular
cuneiforms
cuboid
metatarsal bones
hyperextension of MTP joints and flexion of proximal and distal interphalangeal joints is called
claw toes
resulting from defective actions of lumbrical and interosseous muscles that cause toe to become functionless
results from weakening of lateral collateral ligament of MTP joint and insufficiency of plantar plate along w pull of extrinsic mms resulting in medial deviation of toe is called
crossover toe
flexion deformity of both proximal and distal interphalangeal joints w MTP in neutral or flexion often combined w rotation =
curly toe
characterized by limited dorsiflexion at talocrural - result of contracture of gastrocs /soleus/achilles =
equinus deformity
where is tailors bunion formed
5th metatarsal
