FOOT ANKLE Flashcards
POST TIB
most powerful foot __
inverter
POST tib
origin
insertion
origin = posterior tib-fib, IO membrane
insertion = navicular tuberosity, plantar MT
after ankle fusion, stride length vs TAA
decr stride length
also decr cadence and velocity
fusion of ___ joint eliminates all hindfoot motion
talonavicular
MC cause of foot osteo
MC cause of foot puncture wound
foot osteo = pseudomonas
foot infection = staph aureus
for TMT fx-dx how to stiff immobilize operatively
1, 2, 3 joint plating
4, 5 K-wire b/c more mobile
first step for tibiotalar arthritis nonop
CSI
rocker bottom shoe
tibiotalar arthritis surgery options
young active
old inactive
young active = fusion
old inactive = TAA
optimal position for ankle fusion
plantigrade
10 deg ER
5 deg valgus
5 mm posterior position talus on plafond
nerve at risk with approach to medial sesamoid
plantarmedial cutaneous nerve
Tx FHL impingement (PM pain , decr passive EHL) after nonop
FHL release at level of ankle
what happens during heel strike
TA eccentric
what happens during swing phase with TA weakness
steppage gait (incr hip/knee flexion) to clear foot
what happens during swing phase
TA concentric
Morton extension for what
hallux rigidus
limits 1st MTP DF
if great toe fused in PF or too straight then
excess lateral pressure on foot (should be 10 deg valgus and 15 deg DF)
flexible pes planovalgus
where is pain?
how to tx
lateral hindfoot pain
tx = medial hindfoot posting
lower rate achilles re rupture with surgery or nonop
surgery
DM cutaneous nerve of hallu br of what
saphenous
loss of medial arch and pes planus after CSI
acute plantar fascia rupture
transverse tarsal joint is
chopart = TN + CC joints
transverse tarsal axes ___ during heel strike when subtalar joint is ___
transvrse tarsal axes PARALLEL when subtalar joint is EVERTED
EVERSION of subtalar joint ___ transverse tarsal joint
unlocks transverse tarsal joint so flexible and shock absorption
inversion –> locks transverse tarsal so inflexible and push off
stage of PTTD
rigid flatfoot
stage 3
