TERMINOLOGY

  • Definitions

    • 3 major divisions
      • Hindfoot: Calcaneus and talus
      • Midfoot: Navicular, cuneiforms, and cuboid
      • Forefoot: Metatarsals and phalanges
    • 2 columns
      • Medial column: Talus, navicular, cuneiforms 1-3, digits 1-3
      • Lateral column: Calcaneus, cuboid, digits 4 and 5
    • Some authors use 2 columns in hind and midfoot but divide forefoot into 3 columns
      • Medial column: 1st toe
      • Middle column: 2nd-4th toes
      • Lateral column: 5th toe
