Final: Foot Flashcards
What arch does the fibularis longus support?
lateral longitundinal arch
What artery gives off the arterial arch and digital arteries?
lateral plantar a.
What is compartment syndrome?
fluid buildup in the compartments of the anterior or posterior lower leg, due to tight fascia wrapped around for good biomechanics
Compression of what nerve can cause foot drop?
deep fibular nerve
Where would you find a high ankle sprain?
distal tibfib joint
T/F: The ankle moves in a biplanar arrangement.
false, triplanar: dorsiflex/plantar flex, evert/invert, supinate/ pronate
Why is it so important that the foot acts as a shock absorber?
All the bones and ligaments allow for it to absorb shocking terrain, allowing other joints to not feel that (like the SI)
What bones make up the hind, mid, and fore foot?
hind = talus and calcaneous mid = cuneiform, cuboid, navicular fore = MT and phalanges
T/F: Foot acts as a rigid lever during pushoff in locomotion.
true
Which part of the foot experiences the most action, mid, hind, or fore?
hind
T/F: There is no motion at the distal tibfib joint.
false, 2 degrees of motion where it widens 1mm
Between what two bones is the tarsal sinus?
talus and calcaneous
What do the lumbricals attach to?
the flexor digitorum longus, and then onto the extensor expansions of the digits
What does the tibialis posterior insert on?
cuboid, cuneiforms, tuberosity of navicular, sustentaculum tali, and the bases of 2-4 MTs
Where is the flexor hallicus longus located, lateral or medial?
lateral, crosses to big toe medially under foot
