Q

Subtalar Joint

A

3 articular facets

  • Posterior: concave Talus, convex Calcaneus
  • 2 Anterior: convex Talus, concave Calcaneus

-Movement = Inversion/eversion = responsible for alignment of Tranverse Tarsal Joint (locking/unlocking of midfoot)

  • Pronated hindfoot = parallel axis = increased movement
  • Supinated hindfoot = NOT parallel axis = decreased movement
