Q

What joint(s) make up the rearfoot?

A

Talocrural (talus + crual [fibula / tibia])

Subtalar (Talus + calcaneous)

Remember the talus sits ontop of the calcaneous so the joint under that would be denoted as “subtalar”

Q

Redflags of foot (not all of them) = fracture / blood flow loss / numbness (use filament for sensation loss - bend till it becomes a C) / cancer (think bottom of foot because nobody puts sunscreen there [basal cell carcinoma]) / DVT
* 5.07

Yellow flags = more psycological symptoms.
* fear avoidance patterns - think chronic ankle insatbility and scared to do something
* Tampa scale of kinesaphobia
* FABQ
* Fear of moving foot

Q

How do you differeinate a L5/S1 radiculopathy from a glute min refferal?

A

Numbness tingling (muscle doesnt do this)

Mobilize the back and if that brings on symptoms im thinking radic (because you’re not touching glute min)

Poke on glute med/min and if that brings on lateral thigh pain = thinking glute med/min

DTR absense = radiculopthy (dont lose these w/ muscle pathologies)

Mytome weakness = radiculopthy

Dermatonal sensation loss = radic

Q

How to do tuning fork test
* what does it test for?

A

stethascope on fibular head and tuning fork on latearl malleolus or like anywhere on there foot and see if the vibrations are bringing on pain

tests for fracture

lack of sound = fracture

So you tap the fibula then put the stethascope on it comparing the sound side to side

Q

KNOW: Where calluses are on the feet can indicate abulation abnormailties (and wear and tear on the shoes)

A
35
Q

KNOW: Bad toe nails can indicate poor blood flow or infection “window to your health”

A
36
Q

What does this indicate?

A

Venous insufficency

causes wheeping wounds. Such bad circulation that the skin gets so thin that the lymph / seris fluid starts seeping out
* very tender / easily brusied

37
Q

KNOW: Ray = metatarsal

A
38
Q
A
39
Q

Elevated1st ray, hypermobile 1st ray and long second metatarsal have been linked with the development of what 3 things

A

1) 1st MTP joint OA
2) Hallux valgus
3) Midfoot OA

40
Q

What does foot supination do to the medial longitudinal arch?

What about pronation?

A

Increases it

Pronation decreases it

41
Q

Is pes planis pronation or supiantion?
* does what to medial longitudinal arch?

A

Pronation

Decreases medial longitudinal arch

42
Q

If you decrease your medial longitudinal arch (think walking in more pronation / pes planis) which bone is required to have more movement and inturn more muscle work is required for stability (more bone movement = more muscle activation for proper stability)

A

Talus is hypermobile in pronation = more muscle activation required for stability
* Can lead to talus OA

43
Q

What are exostoses?

A

External bone growth at the foot
* often causes by abnormal loading
* Think a bunion

44
Q

tibial shape will affect joint mechnicaics

If the pts right tibia is shorter than the left what will they do at the right foot to try and make that limb longer (what will they do at the foot?)

A

Supination becaue it will make the foot seem taller (making that medial longitudinal arch bigger)

45
Q

KNOW: Supination makes you seem taller on one side (more plantar flexion)

A
46
Q

KNOW: Thicker achilies tendon indicates pathology

A
47
Q

Measuring subtalar lets us diliniate between varus and valgus

A
48
Q

If your foot is in supination are you in varus or valgus?

is most of your pressure lateral or medial?

A

Varus

lateral

49
Q

If you’re in rear foot / midfoot supination whats happening at forefoot?

A

Pronation

50
Q

if you see wear and tear on the lateral aspect of someones shoe are they in varus or valgus

A

Foot is in supination which means they’re in varus

51
Q

If your in over pronation of the foot whats happening up the chain

A

tibial external rotation and femoral internal rotation

do it seated and see the movement

NOTE: this is a valgus moment at the knee

52
Q

In valgus what happens to the tibia and femur?

A

Femur = IR
Tibia = ER

53
Q

What motions happen at the femur / tibia in varus?

A

Femur = ER
Tibia = IR

54
Q

If someone measures a average arch of 140 in non weight bearing. Then in weight bearing their foot becomes much more flat (the arch collapses). Would we expect that angle to increase or decrease with this lower arch? Why?

A

Decrease

Because that navicular tuberosity drops making it closer to a right angle than being completely horizontal

He said dont memorize:
* High arch = 150
* Medium arch = 130-150
* Low arch = <130

55
Q

What 3 points is the medial longitudinal arch measured by?

A

1st metatarsal
medial malleolus
navicular tuberosity

56
Q

What is medial / latearl longitudinal arch maintained by? (3)

A

Wedging of tarsal and metatarsals

Tightening of plantar ligaments (spring us back up)

Instrinisc and extrensic muscles of foot + their tendons

57
Q

Diliniate between the intrinisc and extrinsic muscles of the foot

A

Intrinsic = start and end in the foot
Extreinsic = start outside the foot and end inside the foot

58
Q

Would someone doing large motor motions at the foot / ankle be hitting more intrinsic foot muscles or extrinsic foot muscles? Why?

A

Extrinsic because those larger movements are hitting those attachment points that originate outside of the foot. Whereas the intrinsic ones are all within the foot

59
Q

Would a foot pt benefit from intrinsic foot m EX or extrinsic?

A

Both - they both help to support those longitudinal arches

60
Q

are fine motor motions or stabilizations motions at the foot more intrinsic or extrinsic foot muscles?

A

Intrinsic

think toe stretchs / marbel pick up (however this even hits some of the extrinsic muscles as well)

61
Q

pes planis or pes cavis?

A

Pes cavis

62
Q

Pes planis or pes cavis

A

Pes planis

63
Q

What is a good break in schedule?

A

wearing the new shoes one hour a day and not all day (because this will cause pain)

64
Q

Whats special about an earth shoe?
* what position does it put you in at the knee?

A

It has a negative heel

Puts you into hyperextension of knee

65
Q

High heels put more pressure in what part of the foot (from squeezing it)?
* what 4 things does this positioning lead 2?

A

Puts more perssure on the forefoot

Leads 2:
1) Hallxus valgus
2) Bunions
3) March fracture
4) Morton’s metatarsalgia

66
Q
A
67
Q
A
68
Q

What position does this person walk in?

A

Supination

69
Q

Swelling on one side of the achilles tendon is intra or extracapsular?

A

Extra

moves all to one side

swelling on just one side

70
Q

Swelling on both sides of the achilles is intra or extra capsular?

A

Intra

it just balloons out

left foot = intracapsular (swelling on both sides)

71
Q

Capsular pattern for the talocrural joint (joint capsule tightness)

What would the benefit from?

A

PF > DF

Benefit from mobilization EX

72
Q

What joint does the most PF/DF

A

Talocrural

73
Q

1st MTP capsular pattern of resitrction

A

EXT > flexion

74
Q

IP joints capsular pattern of restriction

A

Flexion > extension

(less worried about us knowing this one)

75
Q

is soleus or gastroc a 2 joint muscle?

A

Gastroc

76
Q

Make sure you touch up on thomas test

A
77
Q

Which muscle is most likely to limit great toe extension (which affects push off and our ability to ambulate)

A

Flexor hallasos longus

78
Q

Special test high ankle sprains:
* External rotation stress test (Kleiger)
* Squeeze Test
* Cross Leg test

Lateral ankle sprains
* Anterior drawer - ATFL
* Talar Tilt - CFL

Talocrural impingement (feels like a pincching sensation)
* Impingement sign + TIC

Achilles Rupture
* Thompson test (squeeze gastroc and if they plantar flex it isnt ruptured)

Plantar Fasciitis
* Windlass test
* However, the best test is subjective pain –> first few steps such –> palpate on medial calcaneoal tubericle and it ligths them up

Tarsal tunnel
* Tinel’s test (more medial)

Morton’s Neuroma / Stress Fracture
* Squeeze test
* You are squeezing the metatarsals togther and seeing if this recreautes your pain. Numbness / tingling = mortons neuroma. Sharp pain = fx

A
79
Q

What two ligaments are most likely ruptured w/ lateral ankle sprains?

A

anteriortalofibular ligament

calcaneofibular ligament

80
Q

How much extension at the MTP do you need for walking?

A

65 degrees

81
Q

How much extension do you need at the MTP for running?

A

85 degrees (you’re now really loading into the MTP)

82
Q

CT scan is used for what? (6)

A

Bone tumors

Fractures: acute and stress fractures

Non-unions or delayed unions

degrenative and rhematoid arthritits

Post op monitoring

avascular necrosis

83
Q

MRI is used for what in the foot? (4)

A

Tendinopathies and tears (however ultrasound is better if a skilled pro is using it)

Show areas of subtle changes within the substance of the tendon

Ligament disruption

Osteochondral fractures of the talar dome
