Ankle Flashcards
Talus is thicker
Anteriorly
Pronation includes
DF
ABD
EV
Supination includes
PF
ADD
INV
Gravity has tendency to
force us into anterior fall
PF (gastroc/soleus) control this tonically
Supination twist
WB as go into heel strike Calc everts (so forefoot supinates) Plantar ligaments tighten Talus ADD IR of tibia
Subtalar joint is what
Talus with calcaneus

Windlass effect
Plantar fascia from calcaneus to first row of phalanges
When you DF you foot, you would think the arch would be flat because fascia tight - BUT actually the arch becomes caves because of DF and aponeurosis inc cavus!
Windlass test - big toe extension
3 arches of the foot
medial and lateral and 1 transverse
Trans - intermed cuneiform
Med - talus and navicular
Lat - cuboid
Add strength, stability, mobility, resilience
Shock absorption, dissipate energy
Ottawa ankle rules
Inability to WB 4 steps after
Bony tenderness to posterior malleoli edge
Bony tenderness 6cm above either malloelus
Bony tenderness at navicular
Bony tenderness over base of 5th MT
At initial contact, what does the calcaneus do?
Calc EV
Rearfoot pronation
At push off - calc does what
Calc INV
Rearfoot supination
When calc evers, the tibia
IR
When calc inverts, the tibia
ER
NWB forefoot is in varus, in WB the forefoot will
Pronate
Calc EV
Tibia IR
Because IR tibia is coupled with knee FLEX, this will cause a knee flexion moment at the knee and IR at the hip
