calcaneus

forefoot

talus

tibia

A
  • Supination
    • Calcaneal inversion
    • Forefoot plantar flexion
    • Talar dorsiflexion and abduction
    • Tibial external rotation
  • Pronation
    • Calcaneal eversion
    • Forefoot dorsiflexion & abduction at MTJ
    • Talar plantarflexion and adduction
    • Tibial internal rotation
3
Q

CKC pronation = _______leg rotation

A

internal

4
Q

limitation of the TN jt results in …

A

loss of majority of STJ ROM

5
Q

goals of tx for flexible pronated foot

A
  • Increase the moment of ground reactive force medial to the STJ/MTJ axis
  • Move effective STJ axis lateral (more foot medial)
  • Reduce hypermobility
  • Orthotics or surgery
6
Q

goals of tx flexible supinated foot

A
  • Increase the moment of ground reactive force lateral to the STJ/MTJ axis
  • orhotics or surgery
7
Q

goals of tx rigid foot

A
  • Improve the static position of the foot
  • Surgery to reposition segments
  • Changes in GRF do not help change position in a rigid foot
8
Q

If we move a segment of the foot either medial or lateral to the effective STJ / MTJ axis we change the GRF acting on the whole foot and induce supination if …

A

the effective axis becomes more lateral and pronation if the axis moves medial

9
Q

what happens to kite’s (talocalacaneal) angle with pronation?

A

increases

10
Q

lateral kite’s anlge with supination will …

A

increase

11
Q

CORA center of rotatoin angulation

A

intersection of the PAA proximal anatomic axis and DAA dital anatomic axis of the two segments being correction

12
Q

ACA angulation correction axis should be ..

A

at the CORA
