Q

eversion ankle sprain
objective exam:

special tests:

A

OE:
- limited ankle ROM, especially eversion
- limited ankle strength especially inversion
- TTP to deltoid ligamnet

special tests:
- talar tilt: medial: SN/SP - not reported

  • strucutre taht stops eversion from occuring is gone so limited eversion due to muscle gaurding/protection

Q

posterior tibialis tendon dysfunction
objective exam:

Study These Flashcards
A
  • SL calf raise
  • inversion strength tests
  • subtalar joint mobility assessment
  • midfoot mobility assessment
24
Q

posterior ribialis tendon dysfunction

some ‘why’s’ that need to be assessed?

Study These Flashcards
A
  • talocrural joint restriction
  • great toe joint restriction
  • decreased strength of tibialis anterior, gastroc- soleus complex and or fibularis longus/brevis

more force through midfoot

25
posterior tibialis tendon dysfunction what are the stages of progression
early stage middle stage late stage
26
what are you looking for with early stage posterior tibialis tendon dysfunction
- localized pain - able to perofrm SL calf raise - strong but painful inversion strength tests (and Plantarflexion)
27
What to look for in middle stage poterior tibialis tendon dysfunction
- pain along tendon - rear foot valugs; forefoot abduction - weak SL calf raise - increased mobility of subtalar joint (flexible) - weak inversion strength tests
28
what to look for in late stage posterior tibialis tendon dysfunction
- lateral ankle pain - severe arch collapse - unable to perform SL calf raise - loss of subtalar mobility (fixed) gastroc/soleus PF + supination --> can't do this load greater than capacity
29
syndesmotic injury (high ankle sprain) subjective exam: MOI?
MOI: external rotation of the foot when dorsiflexed and pronated (head of talus pushes laterally on fibula) - high pain levels - difficulty weight bearing - may report feelings of instability - less swelling than other ankle sprains ## Footnote remember fibula is non weightbearing so you can still walk = more pain
30
syndesmotic injury (high ankle sprain) objective exam
- limited ankle palnatar flexion ROM - pain with ankle ER ROM - pain with force ddorsiflexion ROM (spreads apart tib, fib) - inabiltyto perofrm a sinlge leg hop - palpation SN: 92% (not painful = good confidence not a high ankle sprain)
31
Syndesmotic injury (high ankle sprain) special tests
dorsiflexion-external rotation test (kleiger test) SN: 71% squeeze test SP: 99-94% sibular translation test: neg test: SN 82% SP 88% ## Footnote the more proximal you go on a squeeze test with reproduction of pain symptoms the more concerning the sprain is (pain produced at distal tib/fib)
32
what are some secondary injuries to a syndesmotic injury? what is the prognosis of a syndesmotic injury?
determine if secondarily a fracture occurred especially to fibula, deltoid ligament injury prognosis: worse than other ankle sprains grade I: 4-8 weeks grade II: 2+ months grade II: 3-6 mohts (likely srugical intervetion)
33
34
inversion ankle sprain (lateral ankle sprain) indications during examination:
- sudden onset with ankle inversion injury - negative ottawa ankle rules - positive special test - TTP to ATFL
35
inversion ankle sprain (lateral ankle sprain) due to possible secondary injury, need to determine if the following have also occurred:
- fracture: distal fibula, distal tibia, 5th metatarsal, navicular - bone contusions - epiphyseal plate injuries - cuboid subluxation (sits plantarly and feels like walking on pebble) - nerve injury (superficial/deep fibular N.)
36
what are some 'why's' that need to be assessed for inversion ankle sprains (lateral ankle sprain)
talocrural joint restriction hip abduction/external rotation strength
37
chronic ankle instability can come down to what factors?
- functional (sensorimotor) - mechanical - combo ## Footnote motor control takes over for mechanical instability
38
chronic ankle instability: indications during examination
- may or may not have pain - report of instability or giving way - history of at leat one significant ankle sprain - episode of subsequent sprain or perception of ankle instability - decreased performance on functional tests - pt reported outcome measures (PROMS or PROs)
39
and identification of functional ankle instabilty score of 11+ or a cumberland ankle instability tool score of 25 or less could lead us down to thinking?
possible chronic ankle instability
40
fibular tendons predisposed to:
- tendinopahty - tear - subluxation
41
fibularis subluxation indications during exam
" snapping" reported w/ ankle movements (e.g. circumduction) ankle DF and eversion - may or may not have swelling - history of traumatic nakle injury (like ankle inversion sprain) - positive fibularis subluxation test (SN/SP not reported) prognosis is poor
42
# ankle/foot impingement indications:
- pain with activites that cause repeated compression or distraction forces to soft tissue surrounding talocrural joint superficial ankle pain
43
classification of ankle impingement
Grade 0: normal joint space; possible subchondral sclerosis Grade I: normal joint space; presence of bone spurs Grade II: joint space narrowing Grade III: total loss of joint space
44
# ankle/foot anterior impingement CPR: ## Footnote 6 things
1. anterolateral joint tenderness 2. anterolateral joint swelling 3. pain w/ forced DF 4. pain w/ SL squat 5. pain w activity 6. absense of ankle instability (the feel structuraly sound, absense of hypermobility) if 5 out of 6 of these then (+) for anterior ankle impingment SN: 94% (<5), SP: 75% (5 or 6) ## Footnote possible hard end feel
45
osteoarthritis subjective exam
no MOI - gradual onset morning pain stiffness that decreases after moving around for 30-60 minutes (if they sit fora while then will be stiff again) deep joint pain more often secondary due to previous injury
46
osteoathritis objective exam:
- decreased ROM (capsular pattern) - TTPalong joint line
47
posterior ankle impingment indications:
- pain with plantarflexion activities - pain w/weightbearing - superficial ankle pain - positive heel thrust test due to possible secondary injury need to determine if FHL injury occurred ## Footnote What are some differences between anterior/posterior ankle impingemet, difference between achilles tendinopahty and this?
48
os trigonum syndrome
posterior ankle impingment from accessory bone in posterior ankle. the accessory ossicle w/softtissue becomes wedged between the tibia, talus and calcaneus - often symptoms are bilateral ## Footnote top of a calf raise could be painful
49
achilles tendinopathy subjective exam:
no MOI - gradual onset - may or may not have visible sweeling (inflammatory type presentation) - pain w/ first few steps in the morning ( if not reported consider ruling out SN 89%) - as condition progresses, onset of pain occurs earlier in the activity (same as tibialis posterio tendinopathy)
50
how do the nuances of tendinopathies presesnt similarly? what are the main differences that set them apart? - really challening to memorize each individually. think big picture what would a tendinopahty present like? then what could lead you down the path to pin point what kind? for example how do you know its achillies instead of posterior tibialis?
think girl think!
51
achilles tendinopathy objective exam:
- pain with palpation positive test: SP 81% test cluster: palpation, royal london hospital test, arc sign
52
What are some whys that need to be assessed with achilles tendinopathy
- rearfoot alignment (doesnt take horizontal force very well) - gastroc-soleus, tibialis posterior, FDL/FHL strength
53
What are the 4 stages of achilles tendinopathy
1. no pain during activity; soreness in AM; minimal crepitus 2. pain during activity; no loss of function; TTP; grepitus present 3. pain limitingfunction; soreness through the day; crepitus 4. unable to function due to pain; soreness throughout day; crepitus
54
achilles rupture - most frequently rupture tendon risk factors
- long term corticosteroid use (auto immune, asthma, other medical reasons) - hypercholesterolemia - gout - RA, lupus - long term dialysis (parathyroidism weakens tendons due to altered calcium and phosphorus lvls in the body associated w/ kidney disease) - renal transplant
55
achilles rupture subjective examination
- acute injury - feelings of being kicked in posterior ankle - felt a pop - difficulty weight bearing
56
achilles rupture objective exam
- + thompson test - + matles test - palpation of gap (3-6 cm above calcaneal insertion)
