Q

what happens to the talus during plantarflexion

creating what…

A

it slides anteriorly and disengages from the tib/fib

this creates increased joint mobility and decreases stability

Q

when can a spiral fracture of the tibia occur

A

22
Q

what are the rules of threes

A

T1-T3: SP even with TP

T4-T6: SP 1/2 level below TP

T7-T9: SP one full level below TP

T10: SP full level below TP

T11: SP 1/2 level below TP

T12: SP even with TP

23
Q

posterior tibialis action

A

PF

IV

24
Q

function of the intervertebral foramen

A

protect the spinal nerve roots as the exit the cord

25
Q

the femoral artery leads into the ___ artery

A

popliteal artery

26
Q

where are uncinate joints found and what are they for

A

C3-C7

limit lateral flexion

27
Q

what is lordosis

A

increased anterior curvature (most often lumbar spine)

28
Q

what is kyphosis

A

excessive posterior curvature of the thoracic spine

29
Q

what femoral condyle descends further inferiorly

A

medial

30
Q

what motions comprise open-chain supination

A

PF

IV

ADD of calcaneus

31
Q

where does the longitudinal arch run

A

calcaneus to the metatarsal heads

32
Q

fibularis longus and brevis action

A

EV

longus pronates too

33
Q

what tendon is the dorsalis pedis artery just lateral to

A

EHL

34
Q

how long can tibial fractures take to heal

A

6 months

35
Q

tightening of the plantar fascia causes

A

supination of calcaneus

IV of subtalar

(eventually causes rigid lever for push off)

36
Q

pronation or supination:

in gait, P OR S? allows the foot to conform to irregular surfaces and when P OR S?, the joint acts as a rigid lever for propulsion

A

pronated - conforms to irregular surfaces

supinated - acts as a rigid lever for propulsion

37
Q

three MOIs for ACL injury

A
  1. tibia driven anteriorly on femur
  2. femur driven posteriorly on tibia
  3. knee joint is hyperextended with IR
38
Q

how can avulsion of the tuberosity on the 5th metatarsal bone happen

A

violent inversion

39
Q

what would someone with central cord syndrome have most difficulty doing

A

placing marbles into a cup

40
Q

what motions comprise close-chained pronation

A

PF

ADD talus

EV calc

41
Q

for central cord injuries, are sensory or motor deficits more present?

A

motor

42
Q

what muscles stabilize the medial arch

A

fib longus

posterior tibialis

intrinsic muscles

43
Q

it is essential to palpate the dorsalis pedis pulse in order to rule out…

A

intermittent claudication

44
Q

during DF, what happens to the talus

A

talus rotates laterally 30 degrees

45
Q

when and where can the popliteal artery be palpated

A

popliteal fossa when the leg is slightly flexed

46
Q

what muscle attaches to the lateral meniscus

A

popliteus

47
Q

what does supination do to the tibia

A

ER

48
Q

what motions comprise open-chain pronation

A

DF

EV

ABD of calcaneus

49
Q

what happens to the talus during dorsiflexion

creating what..

A

it slides posterior on the tibia

this creates joint stability and decreases joint mobility

50
Q

most frequent location for fractures of the tibia

A

middle of the shaft (narrowest part)
