1

supination =

pronation =

inversion, plantarflexion and adduction

eversion, dorsiflexion and abduction

2

CKC actions for supination and pronation at ...

calcaneus

forefoot

talus

tibia

  • 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

CKC pronation = _______leg rotation

internal

4

limitation of the TN jt results in ...

loss of majority of STJ ROM

5

goals of tx for flexible pronated foot

  • 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

goals of tx flexible supinated foot

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

7

goals of tx rigid foot

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

8

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 ...

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

9

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

increases

10

lateral kite's anlge with supination will ...

increase

11

CORA center of rotatoin angulation

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

12

ACA angulation correction axis should be ..

at the CORA

13
