Q

Why is hip OA associated w/ muscle weakness?

A

The pain around this joint keeps them from fully using them hip which quickly leads to atrophy - causing the muscle to be weaker

Q

Why does hip OA cause balance issues

A

Think if they go into a trendelenberg to get away from affected side that causes them to already be off balance

Fear avoidance (fear of falling = increased risk of falling)

Altered joint mechanics - aka joints arent sending great proprioceptive information (because they’ve been damanged from taht general wear and tear) your body won’t know where it is in space - leading to an increased fall risk

Q

Could someone w/ hip OA have a positive trendelenburg? Why

A

Yes

Because trenedelnburg is caused by poor hip abductor (think glute med) strength. These muscles atrophy from disuse misuse w/ hip OA leading to this sign

Q

What two motions are most limited w/ hip OA? which one is more limited?

A

Internal rotation is the most limited movement followed by hip flexion

NOTE: AB / EX is also somewhat limited (probs don’t memorize)

This is because these two motions close down the most on that joint capsule

Q

Which two accessory movements are typically limited w/ hip OA? why?

A

Posterior / inferior glide

This makes sense. The hip is a convex on concave (opp). Internal rotation = anterior roll = posterior slide (joint assessment). Flexion/abduction = superior roll = inferior slide (asses)

Q

Which 2 muscles would we MMT for

A

Glute med (abduction) / glute max

atrophy of these two muscles are highly correlated w/ hip OA

We flex or hips a lot more than we extend them meaning glute max could be atrophing (+ extension is one of those movements we won’t be doing as much w/ hip OA)

Glute med because we stop abducting because it hurts and when we stop using it we start losing it.

Q

What is a Scour test? Is it good for hip OA

A

Them jamming the hip in the acetabulum and then grinding the hip from a 12 a clock position to a 2 a clock position back and forth (out in out in)

Think a scouring pad to clean a dish

It’s good for figuring out if someone for sure doesnt have hip OA. If we do this test and there is no pain then the person almost def doesnt have hip OA. However, a posititve doesnt mean it is hip OA (could be a 100 other things)

Q

What is the Clinical prediction rule for hip OA? How many factors do we need

A

1) Self-reported squatting as an aggravating factor (closing down the hip space - cramming down on the hip joint)
2) PASSIVE IR of involved side less than or equal to 25 degrees
3) Active hip flexion causes lateral hip pain (think about head moving laterally)
4) Active hip extension causes hip pain
5) Postitive Scour test w/ adduction (not when you scour out but when you scour in [maxiamlly closes down hip joint]) in the ground or lateral hip

NOTE: Hip OA pain is typically in the groin (anterior hip) or lateral hip (trochanteric area)

We need 4/5 of these to be posititve to rule in hip OA

Q

Whats a big disease thats associated w/ femoral stress fractures?

A

osteoprosis

64
Q

**What kind of pain is with femoral stress fracture? where is this pain?

A

proximal anterior or latearl hip and groin region (almost exactly the same pattern as OA). Deep aching pain

65
Q

Is femoral stress fracture pain better w/ EX or rest?

A

Better with rest (EX hurts - its a fracture)

66
Q

Whats a huge differeinating factor with hip OA and femoral stress fracture?

A

Femoral stress fracture has a traumatic MOI while OA is a degenerative disease.

NOTE: They both have the same pain pattern - anterior and lateral thigh / groin

67
Q

What would be two good outcome measures to use for a 45 year old male with a hip fracture?

A

LEFS and Hip outcome score (more functional)

68
Q

What outcome measure would we use for a 67 year old sedentaory female w/ femoral stress fracture?

A

Hip outcome score

We wouldnt use LEFS because it involves more active stuff (jumping / running)

We wouldnt use HOOS because it tests specifically for OA

69
Q

How would someone w/ a femoral stress frature be expected to hold their hip in the clinic?

A

Would come in with hip flexion, abduction, external rotation (most open packed position)

70
Q

what motion would have weakness w/ a femoral stress frature? (Post OP)

A

abduction

they would cut glutes to repair causing this motion to be weakened

71
Q

What two tests would we do to rule out femoral fractures?

A

Fulcrum test
Patellar pubic percussion test

72
Q

would a femoral neck fracture or a trochanteric fracure look better from the outside?

A

Femoral neck fracture

It is intracapsular meaning that swelling will be compressed within that joint

73
Q

Does severe swelling normally happen w/ trochanteric fractures?

A

Yes, because it is extra capsular

74
Q

With a trochanteric fracture the leg goes into what position

Which makes it appear ______

A

External rotation

Shorter

KNOW: theres lots of swelling in the surrounding tissue

75
Q

What is the most problematic femoral fracture? (not hard)

A

femoral neck fracture

76
Q

are most femoral neck fractures displaced?

A

95% are - think about it - its a tiny neck meaning it will easily slide apart when broken

77
Q

KNOW: Femoral neck fractures mess up the integrity of the joint itself (because they’re intracapsular)

A
78
Q

Which way does the hip dislocate with dashboard injuries?

A

Posterior fracture dislocation

79
Q

Posterior Hip Dislocations are assocaited w/ what MOI

A

typically dashboard injuries

80
Q

Are anterior or posterior hip dislocations more common?

A

Posterior

81
Q

When a hip has a posterior displacement or dislocation what 3 positions is it in (after the fact)

A

flexion, adduction, IR

82
Q

What motion causes an anterior dislocation of the hip?

A

Exterme extension pushes the head out forward

far less common than posterior

83
Q

This pt was found on the floor unconscious. By looking at them we can insantlly tell whats wrong. Whats wrong and how do we know?

A

This person has a posterior hip fracture dislocation

We know this because they present with an internally rotated adducted flexed leg

84
Q

What population is typically affected by femoral acetabulum impingement?

A

Young healthy active population (20-40)

85
Q

What kind of FAI affected the femoral head and neck?

A

Cam

86
Q

What kind of FAI affects the acetabulum?

A

Pincer

87
Q

What age group typically gets FAI?

A

Young adult active population (20-40)

88
Q

What position is the worst for FAI? (brings on symptoms)

A

flexion, IR, ADD (closes down joint space - or pinch the labrum between it)

89
Q

Is FAI gradual onset?

A

Yes (boney deformitites take time to form)

90
Q

What is a precursor to labral tears?

A

FAI (because those boney deformitites pinch down on it over and over again and cause it to break)

91
Q

repetitive activities + FAI =

A

Labrum tear (constatly pinching labrum until it breaks)

92
Q

KNOW: Sudden twist or pivot / hyperflexion or forced squat can cause that labral tear / impingement (especially when the pt already has FAI)

A
93
Q

C-Shape pain is constisten w/ what?

A

FAI

traditionally inner groin but can radiate laterally to the inner thigh

94
Q

What is pain like w/ FAI?
* what is it like w/ deep squats?

A

Dull achy pain (labrum is constantly being compressed) - however w/ deep rotation / flexion / cutting movements we can bring on sharp pain (being compressed)

95
Q

Hip pain is clicking - what do we think it is? Why?

A

Clicking = labral issue

This is due to decreased pressure in the joints because the labrum is not doing its job and keeping all the pressure in

96
Q

W/ a labral issue would we have increased or decreased joint laxity?

A

increased.

Because the labrum is not doing its job so the joint can slide all over the place (aka why there is also clicking)

pt might say “my hip doesnt feel stable”

97
Q

pt comes in and says hip feels unstable. What is the most likely pathology and why?

A

labral issue

Because the hip sits in a deep acetabulum and should never feel unstable. However, if the labrum is affected that would cause the clicking / sliding out of place

For instance w/ hip OA I would never have an unstable joint just a painful one.

98
Q

Why would prolonged periods of sitting affect FAI?

A

Because of that deep hip flexion

99
Q

KNOW: We typically get inguinal pain (anterior) w/ labral issues (however it might also precent as deep C-shape pain)

A
100
Q

KNOW w/ labral issues prolonged sitting, standiing, walking hurt. If we just had this we might be thinking FAI or OA. However he’ll give us pt demographics that will clue us one direction or another (aka saying that theres cliking or that its a 63 year old female w/ osteoporosis)

A
101
Q

KNOW: We don’t really treat FAI and labral tears very different so its not that important for us to be differentaite them - we treat them both w/ conservative PT

A
102
Q

KNOW: if theres trauma involved more likely to be labral tear than labral irritation (both have clicking)

A
103
Q

For labral issue PT’s what questionaires?

A

Hip Outcome Score (HOS)

LEFS - for someone more functional

104
Q

Someone has chronic labral issues. Is there leg going to be in varus or valgus? Why?

A

Valgus

Because they’re taking wt off that leg and it will cause it to collapse in

105
Q

Does someone w/ chronic labral issues have an anterior pelvic tilt or posterior? Why?

What other back issue would they have?

A

Anterior pelvic tilt. Because if I go fully upright thats going to stretch that anterior hip capsule (most labral issues anterior)

That anterior pelvic tilt is accompanied by increased lumbar lordosis (do it yourself to see) which is common w/ chronic labral pts

106
Q

Why is FAI increased w/ increased body mass?

A

because were adding in more weight on those bones (wolfs law) causes those bones to build up and be deformed

107
Q

What position is the hip held in w/ FAI (or any hip joint issues that invovle effusion or swelling)

typical of pts w/ hip pain

A

Flexion, slight abduction, external rotation (takes pressure off hip)

note: this is how most hip pts sit so we can typicaly rule out lumbar spine if they are sitting like this

108
Q

KNOW: someone w/ labral issues are more likely to have decreased IR

A
109
Q

What 3 motions are limited in labral pts?

A

**Hip flexion, internal rotation, adduction **

NOTE: the other one was the way they were seated this is about their limited motion

This is anything closing down on that joint capsule or pushing on it

110
Q

Becuase labral pts dont like internal rotation or or adduction they are typically held in ER and ABD. Which muscles are adaptively shortened?

A

Because they are held in ER / ABD those muscles are adaptively shortened - so they don’t produce as much strength

Hip flexor weakness is also common
* they typically stay in some hip flexion as to not stress the anterior joint capsule which causes the hip flexors to adaptively shorten and weakened

111
Q

Which special test would be used to rule out FAI / labral tears?

A

FADIR (Anterior labral tear test)

especially when combined w/

Posterior labral tear test (drop from DAIR inro hip ext, abd, ER)

However - labrum is typically more anterior pain

112
Q

KNOW: Hip scour is often posititve for FAI/Labral tears because it puts you in a lot of the other posititve positions

A
113
Q

Would a person w/ labral issues want to swquat more w/ ER or IR?

A

They would want to squat w/ ER (helps it not be closed down as much)

KNOW: W/ OA proably both ER/IR is going to such but w/ this only one is stretching the joint capsule

114
Q

Whats the best way to differentiteate labral tears and FAI?

A

MOI (traumatic vs non-traumatic)
- think piviting twisting causing the traumatic event

115
Q

KNOW: FAI is a precursor for OA (and labral tears)

A
116
Q

Do labral pts have tenderness w/ palpation?

A

No, its a really deep area

117
Q

what two scans are best for labral issues?

A

MRI –> CT

What is the most common cause of a greater troachanter bursitits or tendinopathy?

A

Direct trauma

(other related causes are mechanical overload / obesity)

119
Q

KNOW: greater trichanteric bursitits can be brough on by changing up something from normal (think new shoes)

A
120
Q

KNOW: Females are more likely to get bursitits / gluteal tendinopathy

A
121
Q

KNOW: A middle aged secretary thats over weight w/ a trendenlberg = every greater trochanteric bursitits pt ever

KNOW: female is more common for this than men

especially if they have lateral hip pain

A
122
Q

KNOW: greater trochanter pain is lateral

A
123
Q

KNOW: Greater troachnteric bursitits will be tender to palpation over the greater trochanter

A
124
Q

How would you differentiate hip OA and greater trochanteric bursitits?

A

They both cause lateral hip pain

However, greater trochanteric bursitits has tenderness over the latearl hip while hip OA doesnt

124
Q

What is the biggest red flag for greater trochanteric bursitits?

A

fracture because the MOI is direct trauma

124
Q

Gluteal tendinopathy = greater trochanteric pain syndrome = greater trochanteric bursitits

A
124
Q

What age group are gluteal tendinopathies most common in?

A

40-60

124
Q

How would we bring about the pain for a gluteal tendinopathy?

A

MMT –> stress the muscle pull the tendin and bring on the pain

125
Q

What two things like cause gluteal tendinoatphies

A

traumatic event or repetitive load

126
Q

What tendin is affected by gluteal tendinopathies?

A

glute med

also the IT band runs over the greater trochanter here and is involved

127
Q

What two motions flare gluteal tendinoapthies?

A

Flexion and adduction

it pinches down on the greater trochatner / bursa (causing imflammation of tendin and bursa)

128
Q

What causes snapping hip syndrome?

A

Tight ilipsoas

feels like its snapping / strumming w/ flexion

129
Q

What kind of people are likely to get gluteal tendinopathies - sedentary or active?

A

Sedentray (muscle stays weak then they go into that pelvic drop causing more issues in that area)

130
Q

Why would someone w/ gluteal tendinopathy have trouble going up stairs?

A

Because they struggle w/ hip flexion / adduction (goes over the bursa and makes it tight) –> so this motion would be painful for them

131
Q

What kind of pain is gluteal tendinopathy described as?

A

Deep ache

132
Q

What position is someone w/ gluteal tendinopahy likely to have when resting

A

flexion (because they’re sitting)
ER
abd

(this is the common hip pattern for sitting)
most open packed position

also it takes them out of that position that tightens up around their greater trochanter (think abd)

133
Q

Would you be able to feel swelling w/ acute greater troachteric syndrome

A

probaly

134
Q

What motions would cause pain w/ greater troachteric pain syndrome? (actively)

A

We said that glute med’s tendin is involved so the motions of glute med (for abd)

**abd / ER / extension **(they have weakness w/ these motions)
* I think its because all the glutes are involved (not just glute med) that these motions are as such
* Theres weakness w/ these motions as well

(would also present w/ decreased extension)

135
Q

What position would cause pain w/ greater trochatneric pain syndrome w/ passive motioun (you’re moving them)

A

add, IR, Flexion (were stretching it causing pain over greater troachnter)

136
Q

Both FAI and greater troachnteric bursitits are capable of causing latearl hip pain. What are 2 ways we can differentiate the two?

A

1) Greater troachnteric pain syndrome is more pinpointed and palpable

2) Greater trochanteric bursitits as weakness w/ extension / ER / abd (because of glute involvement) while FAI does not have this weakness

137
Q

What test would cause pain for gluteal teinopathiy (special test)

A

Ober test

think about the abduction the pt needs to go into for that

138
Q

What muscle group is involved in gluteal teindopathy?

A

Glutes (not just glute med but i’d say thats the most involved)

139
Q

Why might a trendelnburg gate be involved w/ greater trochanteric bursitits?

A

because it invovles a weak glute med

also IT band tightness can be involved because it crosses over

140
Q

Why might gerdys tubercle be painful w/ greater trochanteric burstits?

A

Because the IT band is affected (tight) w/ this and it inserts on gerdys

141
Q

20 year old pt walks into clinic complaining of lateral hip pain. What do they most likely have

A

We know that FAI presents in pts that are younger so we would pick this instead of the greater troachnteric pain syndrome (those pts are typically 40-60 and more obese)

142
Q

20 year old pt walks into clinic complaining of latearl hip pain after traumatic fall. What do they most likely have.

A

Greater trochanteric pain syndrome

while they are part of the younger population that traumatic MOI makes clues us in here

143
Q

What nerve passes deep to the piriformis?

A

Sciatic nerve

144
Q

Pregnant indivudal has pressure on a nerve. which one is it?

A

Obturator (think about where it comes out / innervates)

145
Q

Femur / pelvis fractures / dislocations would most likely affect which nerve?

A

femoral nerve

146
Q

Weakness in knee flexion is led back to what nerve?

A

sciatic nerve tibial division

147
Q

what nerve causes adductor weakness / sensory loss medial thigh if damaged?

A

obturator

148
Q

pt has obturator nerve damage. What gait pattern do they use and why

A

circumduction

this is a typical pattern fro adductor weakness (take it out wide so that gravity pulls it back in)

149
Q

What most likely causes damage to femoral n

A

gynecological intervention (urologic / pregnancy)

this is because its put on stretch w/ this

150
Q

pt presents w/ weak hip flexion / knee extension. What nerve problem do they most likely have

A

femoral

151
Q

What special test do we do to test femoral n?

A

Elys test (this is the test that does rec fem)

152
Q
A

Lower Test 1 (13 decks)
