Flashcards in 04 Foot Exam 2 Deck (23):
When you're palpating the talus to to find subtalar neutral, what are you actually feeling?
- laterally: dome of talus
- medially: head of talus
neutral foot position: clinical significance
ideal foot position during midstance phase of the gait cycle
What happens with deviation from neutral position during gait cycle?
- compensatory changes
- lead to increased tissue stresses and pathologies
To "feel" the motion of the entire LE, what position should you be in?
What position does the foot always try to seek?
plantigrade position (entire foot in contact with WB surface)
- joint is unable to make up for poor position
- doesn't get to the ground if joints don't allow compensation
- able to make up for poor position or lack of normal motion
- able to get to the ground if joints allow
second ray and second metatarsal are longer than the first
percentage of the population with Morton's foot
problem with Morton's foot
vulnerable to stress fracture
What structure is important for the windlass effect?
medial longitudinal arch
observing the windlass effect
- extend MTP
- arch rises up
- center or medial malleolus to center of MTP joint
- ID navicular tuberosity in relation to the line
Feiss' line: WB or NWB?
Feiss' line has __ divisions
Feiss' line: navicular is within topmost division (1˚)
Feiss' line: navicular is within middle division (2˚)
Feiss' line: navicular is within lower division (3˚)
What is a better test than Feiss' line?
navicular drop test
positive finding on navicular drop test
> 10 mm
longitudinal arch angle: low medial arch
longitudinal arch angle: medium medial arch
