Flashcards in Lower Quarter 2 Deck (47)
What are the anatomic osseous structures of the foot and ankle?
calcaneus (sustenaculum tali)
cuniforms (medial, intermediate, lateral)
metatarsals (base of fifth)
phalanges (proximal, middle, distal)
What are included in the lateral collateral ligament of the foot?
anterior talofibular ligament
posterior talofibular ligament
What is included in the medial collateral ligament of the foot?
What makes up the deltoid ligament of the foot?
What is considered the spring ligament?
What is considered the short plantar ligament?
Where does the long plantar ligament attach to?
calcaneous to cuneiforms/cuboid
Where does the plantar fascia attach to?
calcaneous to proximal phalanges
What are the functional segments of the foot?
What are the functional joints of the foot?
What motions are triplanar motions?
pronation (abduction, eversion, dorsiflexion)
supination (adduction, inversion, plantarflexion)
What is the classification of the talocrural joint?
What are the motions and degrees of freedom of the talocrural joint?
1 degree of freedom
What plane and axis does the talacrural joint move in?
What is the closed-pack position of the talocrural joint?
What is the classification of the subtalar joint?
composite (uniaxial joint allowing triplanar motion)
What are the motions and degrees of freedom of the subtalar joint?
3 degrees of freedom
what is the axis of the subtalar joint?
What is the closed packed position of the subtalar joint?
What is the classification of the transverse tarsal joint?
compound joint (talonavicular, calcaneocuboid)
What are the motions and degrees of freedom of the transverse tarsal joint?
supination (talonavicular-inversion, calcaneocuboid-adduction, plantarflexion)
pronation(TN-eversion, CC-abduction, dorsiflexion)
three degrees of freedom
What is the axis of the transverse tarsal joint?
What is the close-packed position of the transverse tarsal joint?
What is the classification of the tarsometatarsal joint?
What are the motions of the tarsometatarsal joint?
dorsiflexion (with slight inversion)
plantarflexion (with slight eversion)
What is the plane and axis of the tarsometatarsal joint?
What is the closed packed position of the tarsometatarsal joint?
What are the rays of the foot?
A functional unit formed by a metatarsal and its associated cuneiforms.
Where do the rays articulate?
Rays 1-3 are associated with the cuneiforms as they articulate on the navicular
rays 4-5 only articulate with the cuboid
