Q

During open chain dorsiflexion of the talocrural joint the tib/fib rotate _______ and slides _______

A

Medially, superiorly

23
Q

Plantarflexion at TC joint open chain

A

Slight inversion must occur at the subtalar joint
Occurs due to oblique axis

24
Q

Plantarflexion at TC joint open chain the tib/fib rotate _____ and fibula adducts and slides _______

A

Laterally, inferiorly

25
Q

Lateral colateral ligament has ___ bands to limit inversion/ varus strain

26
Q

ATFL limits plantarflexion
PTFL limits dorsiflexion
Both also limit ________

27
Q

Talocrural joint CPP

A

Full dorsiflexion

28
Q

Talocrural joint Capsular pattern

A

Plantarflexion > dorsiflexion

29
Q

Talocrural joint typical dislocation

A

Uncommon, posterior more common than anterior, due to trauma Typically see malleolar fracture first

30
Q

Talocrural joint open chain _____ talar dome moves on stationary ______ distal tibia

A

Convex on Concave thus opposite directions

31
Q

Talocrural joint closed chain _______ distal tibia moves on stationary _____ talus

A

Concave on Convex thus same directions

32
Q

Subtalar joint has __ bands within the sinus tarsi which restrict end range ________

A

2 bands ant/post, end range eversion

33
Q

The true _______ subtalar joint consists only of the ______ articulation because it has its own capsule

A

anatomical
posterior

34
Q

Subtalar joint CPP`

A

Full supination

35
Q

Subtalar joint Capsular pattern

A

Varus (inversion) > Valgus (eversion)

36
Q

Subtalar joint typical dislocation

A

Talar dislocation relatively rare
Calcaneal impaction from landing hard on the heel can sublux talus but not often dislocate it

37
Q

S-shaped articulation that acts as a bridge between hindfoot and midfoot

A

Composed of 2 seperate joints:
Talocalcaneonavicular: talocalcaneal/talonavicular joint
Calcaneocuboid joint

Transverse tarsal joint

38
Q

Talocalcaneal joint classificaton

A

Uniaxial plane synovial joint

39
Q

subtalar and Talocalcaneal joints are in which axis

A

Oblique triplanar axis (axis bisecting all 3 planes)

40
Q

roll/glide for the subtalar/talocalcaneal joint in closed chain

A

posterior Concave talus moves over (relatively) stationary convex calcaneus
Thus roll/glide are in the same direction

41
Q

Pronation in closed chain

A

Calcaneal eversion
Talar head: add/plantarflxn
internal rotn of tib/fib
medial longitudinal arch depresses

42
Q

Supination in closed chain

A

Calcaneal inversion
Talar HD: Abd/dorsiflxn
ext. rotn of tib/fib
Medial longitudinal arch elevates

43
Q

roll/glide for the subtalar/talocalcaneal joint in open chain

A

Convex calcaneus moves over the concave talus
Thus roll/glide is in the opposite direction

44
Q

Supination in open chain

A

Calcaneus: inversion, adduction, plantar flexion

45
Q

pronation in open chain

A

calcaneus: eversion, abduction, dorsiflexion

46
Q

talonavicular joint open kinetic chain

A

concave proximal navicular moving on convex talar head
Same

47
Q

Talonavicular joint closed chain roll/glide

A

Closed is opposite
talar HD moving on navicular

48
Q

Plantar calcaneonaviuclar (spring) ligament

A

Supports talus and therefore the medial longitudinal arch

49
Q

Talocalcaneonavicular (TCN) CPP

A

Supination

50
Q

TCN joint capsular pattern

A

Dorsiflexion > PLnatar flexion of talar HD

51
Q

TCN typical dislocation

A

uncommon, more common fracture

52
Q

TCN joint blood supply/innervation

A

anterior tibial artery
Plantar and deep fibular n.
