ankle pathologies Flashcards
what is a primary consequency of hallux valgus?
hypermobility of the 1st MT
what is the main cause of hallux valgus?
hyperpronation during propulsive phases of gait
shoes too narrow which compress the feet
what can hallux valgus be identified clinically?
1st MT is adducted on medial cuneiform relative to midline
1st phalynx is abducted on MT relative to midline
how can hallux valgus be treated
correct for the hyperpronation w/ strenghtening of the intrinsic muscles and posture or orthosis
taping for temporary pain relief
what is plantar fasciopathy?
histological degeneration and deterioration of collagen fibers, increased secretion of ground substance proteins and fibroblast in areas of proliferation
what clientele is affected by plantar fasciopathy?
- very active people
- people w/ a shigh standing workload
what causes plantar fasciopathy?
degenerative causes due to excessive and repeated loading
low arches: increase the stress in order to stabilize the arch
high arches: inability to pronate foot and thus decreased shock absorption and thus increase stress on foot
-poor MTP extension = poor windlass mechanism = increased stress on plantar fascia
-tightness of myofascial structure = increased pronation or increased tension on fascia
what is the most common MOI(s) for plantar fasciopathy?
overuse injury (insidious)
WB activivity s/a running
activities w/ excessive mvmt, foot pronation or stressing/stretching of plantar fascia (MTP in full extension, foot hyperpronated or foot hypersupinated)
what is the pain site for plantar fasciopathy?
medial tuiberosity of calcaneus and extends along the medial border of the plantar fascia
what is the pain pattern for plantar fasciopathy?
pain worse in am or post activity in WB
if more severe: pain w/ NWB
pain increases w/ mvmt stretching/stressing of the plantar fascia
hwta can be noticed in gait in a foot w/ plantar fasciopathy?
hypersupination or hyperpronation
what is the effect of having a foot hypersupinated
poor motion of tbhe bones thus excessive load on the fascia
what is the effec of foot hyperpronated?
hypermobility
how is the ROM in a foot w/ plantar fasciopathy?
MTPs full extension might be painful and stiff
how is palpation for plantar fasciopathy?
pain on medial tubercle of calcaneuse
might have a heel sput; which is generally painless
what results from flexibility testing for plantar fasciopathy
stiffness
what test can be used to test flexibility in plantar fasciopathy? explain the test?
windlass test
pt in WB is asked to bring hallux into full extension, the arch should rise
might be painful
if nothing happens or is delayed –> weakness
if needs lots of force before being initiated –> stiffness of the fascia
can imaging be used for plantar fasciopathy?
only is conservative Rx is uneffective it is used to detect changes in the facia or heel spurs
how can we decrease pain in plantar fasciopathy
- avoid aggravationlload reduction
- ice and NSAIDs to reduce inflmmation
- taping to elevated fascia
when is stretching used as a tx option for plantar fascipathy? what stretches cn be done
when the plantar fascia is stiff w/ windlass test
-PROM MTP exrtension, full ankle DF
STT, self massage
what grading techniques ares used for mobilization of 1st MTP in extension?
grade 3 and 4
what strenghtning is suggested for plantar fasciopathy?
- hyperpronated foot: STR of intrinsic muscles of the foot
- might want to STR tibialis post and hip ABD/ER
exercise prescribed for plantar fasciopathy?
- pt raises the medial arch of the foot and asked to keep edge in contact w. groun and 1st MTP w/ toe resting normally on floor.
goa: 10 reps of 10s hold 4-5x per day
how can the biomechanics be corrected in the case of plantar fasciopathy?
- taping: only temorary while strengthening intrinsic muscles
- orthodics or new footwear
- othoses
what other Rx options are availible if consevrative Rx doesnt work for plantar fasciopathy?>
-corticosteroid injections for 4-6 weeks
high load STR exercise: HSR protocol
extracorporeal shockwave therapy
-surgery
what can be used to rule out ankle fx?
ottawa ankle rules
what is a grade 1 sprain?
-local tenderness
-microtear or overstretched
-minimal or no swelling
-lig stress test: no grap, normal EF, painful
POP over ligament
what is a grade 2 sprain?
macroscopic tear
marked POP over ligament
localized swelling/ bruised
lig stress test: gap, firm EF, pain
what is a grade 3 sprain?
complete rupture of ligament
+/- pain
swelling common, no tenmse effusion, fluid can circulate
lig stress test: gap ++, soft EF, may or may not have pain
which b/w MCL and LCL is more commonly ruptured?
LCL of the ankle since MCL is stronger, however rupture of MCL will take longer to heal
which ligament of the LCL of the anle is most commonly sprained?
ATFL since lease elastic component of the LCL
what is the sequence of ankle ligement sprain w/ inversion injury
ATFL > anterior capsule > distal anterior tibiofibular ligament > CFL > PTFL
how do LCL strains generally occur (MOI)
-inversion mechanis
what is the pain site of LCL sprain?
lateral aspect of the ankle/foot
what is the pain pattern of LCL sprain?
pain w/ inversion –> stretching of the ligament
what observations (swelling) can be observed in LCL sprains
2 patterns of swelling can be observed
- distal to lat malleoli: egg shaped occurs immediately after injury and generally associated w/ ATFL involvement
- swelling may spread to the foot when capsuleis torn of int. tibfib ligment is affected –> sandwhich like foot
what functional tests can be performed in a LCL sprain?
anatalig gait patterns/NWB
torsion test painful w/inversion
how is ROM of a foot w/ LCL sprain?
inversion and PF are painful
hypermobility due to ligament laxity
how is risom w/ LCL sprain?
depends on aaffected structure and pain level
how is proprioception w/ LCL sprain?>
decreased
what are possible Rx for LCL sprain to decrease pain and swelling
-PRICE/PEACE AND LOVE
-avoid heat
electrotherapy
-drainage/massage/ effleurage from distal to proximal
-light mobilizations; grade 1 and 2
what are possible Rx for LCL sprain to restore ROM
-NWB for the first 24h
-PWB until normal heel-toe pattern is obervsed
-AROM as soon as pain permits
DF in WB
-grade 3 and 4 mobilizations
what are possible Rx for LCL sprain to for STR
str in all directions
isometric then isotonic
what are possible Rx for LCL sprain to improve proprioception
5-10 moin/day 5x/week for 8-10 weeks unilateral eo --> ec stable to unstable surface double task
what are possible Rx for LCL sprain to return to functional exercise and activities
once pain free, full ROM and adequate str aand proprioception; ju,ps,. hops, figure of 8, stop and go
what is an anterolateral impingement generally secondary to?
an acute or recurrent ankle sprain in pf and inversion
where does anterolateral impingement generally occur?
ant. inf. tibiofibular lig
ATFL
anterior capsule
where is the pain site for anterolateral impingement
anterolateral side of the ankle
what is the pain type of anterolateral impingement
intermittent catching sensation
what is the pain pattern for anterolateral impingement
- pain present even once sprain has heeled
- pain increases w/ mvmt arom/prom for DF
how is ROM impacted in anterolateral impingement?
decreased DF in WB
catching sensation but no lig instability
can imaging be used for anterolateral impingement?
most reliable is MRI but not commonly used
