Q

inversion is aka

A

lateral tilt

27
Q

eversion is aka

A

medial tilt

28
Q

talocrural compression force during walking

A

4.5 times body weight

29
Q

joint axes at talocrural joint is blank across all planes

A

oblique

30
Q

talocrural joint is blank talus moving on blank mortise in open chain

A

convex, concave

31
Q

dorsiflexion also creates blank because the talocrural joint runs out of SA on the blank side during open chain

A

abduction, medial

32
Q

talocrural dorsiflexion close chained is blank mortise moving on blank talus

A

concave, convex

33
Q

dorsiflexion creates blank during close chained

A

adduction

34
Q

talus has a larger curvature radius on the blank side

A

lateral

35
Q

fibular rotation is blank during dorsiflexion

A

medial

36
Q

fibular rotation is blank during plantar flexion

A

lateral

37
Q

as talus enters the mortise, the fibula glides blank

A

superior

38
Q

proximal tib and fib do not have blank

A

degrees of freedom

39
Q

fusing proximal tib and fib would have a significant impairment on blank motion unlike wrist

A

ankle

40
Q

check rains to dorsiflexion

A

soleus, gastroc

41
Q

check reins to plantar flexion

A

tib anterior, EHL, EDL

42
Q

check reins to eversion

A

tib posterior, FDL, FHL (Tom Dick Harry)

43
Q

check reins to inversion

A

fibularis longus/brevis

44
Q

subtalar joint has blank articulations

A

3

45
Q

anterior/middle facets of calcaneus are blank

A

concave

46
Q

posterior facet of calcaneus is blank

A

convex

47
Q

3 subtalar articulations are separated by the blank

A

sinus tarsi

48
Q

subtalar joint job is the maintain blank

A

foot contact with ground

49
Q

subtalar joint ligament that limits eversion

A

interosseous talocalcaneal

50
Q

subtalar joint ligament that limits inversion

A

lateral talocalcaneal ligament, cervical ligament

51
Q

other lig of subtalar joint

A

posterior talocalcaneal lig

52
Q

subtalar joint has blank motion on a blank axis

A

triplanar, single

53
Q

subtalar joint has blank moving on the blank

A

calcaneus, talus

54
Q

motions of subtalar joint

A

supination/pronation with components

55
Q

in closed chain, subtalar calcaneuswill not blank or blank which causes blank to move instead

A

abd/add, df/pf, talus

56
Q

closed chain supination at subtalar joint

A

calcaneal inversion, talar abduction & dorsiflexion

57
Q

closed chain pronation at subtalar joint

A

calcaneal eversion, talar adduction & plantar flexion

58
Q

closed pack position of subtalar joint

A

supination

59
Q

posterior subtalar facet is blank on blank

A

concave talus, convex calcaneus

60
Q

anterior/middle subtalar facet is blank on blank

A

convex talus, concave calcaneus

61
Q

why subtalar and talocrural joints are both triplanar but have different components

A

-subtalar is oblique axis across planes
-ROM ratio: 4:4:1
abd/add:ev/iv:pf/df

62
Q

most people have a blank at subtalar joint

A

varus moment

63
Q

most people have blank times more supination compared to pronation

A

2

64
Q

subtalar joint is like a blank between the leg and foot

A

mitered hinge
