    end of fibula
  3. What is the largest, most post. tarsal bone?
    calcaneus..heel bone
  4. What is the calcaneal tuberosity?
    projection on the post inferior surface of calcaneus
  5. What is the sustentaculum tali?
    medial superior part of calcaneus, supports medial side of talus
  6. What sits on the calcaneus , inferior to the tibia?
    talus
  7. Where is the navicular bone?
    medial side, infront of the talus
  8. What is the navicular tuberosity?
    projection on the medial side of the navicular
  9. What is on the lateral side of the foot, just proximal to the 4th and 5th metatarsals?
    cuboid
  10. How many cuneiforms are there?
    3 - 1st, 2nd, 3rd
  11. Which metatarsals are WBing?
    1st and 5th
  12. What is the true ankle jt?
    talocrural/talotibial

    • talus and tibia articulate
    • uniaxial synovial
    • PF&DF
  13. Which jts are inseparable?
    subtalar (talocalcaneal) and transverse tarsal (midtarsal)
  14. What jt is located on the inferior surface of the talus and superior portion of calcaneus?
    subtalar/talocalcaneal

    inv/ever
  15. Where is the transverse tarsal jt?
    midtarsal

    • ant. talus and calcaneus articulate with post. navicular and cuboid
    • inv/ever
  16. What are the articulations for the intertarsals/tarsometatarsal jts?
    cuneiforms and cuboid articulate with all metatarsals
  17. Where do the metatarsals meet phalanges?
    metatarsophalangeal jt
  18. What type of jt is the inferior tibiofibular jt?
    • syndesmosis (ligamentous)
    • little to no motion
  19. What is another name for a pronated foot?
    supple foot (flat foot)
  20. What is another name for a supinated foot?
    rigid foot
  21. What toe motion is very important for push-off in gait?
    hyperextension
  22. Which toe is the most mobile?
    1st (great)
  23. What ligament spans the medial ankle, is very thick and strong, and has 4 parts?
    medial collateral (deltoid ligament)
  24. What are the 4 parts of the deltoid ligament?
    • tibionavicular (anterior)
    • tibiocalcaneal (middle)
    • posterior tibiotalar (posterior)
    • anterior tibiotalar (deep)
  25. Where is the lateral collateral ligament located?
    • lateral lig
    • lateral malleolus and talus to navicular
    • 3 parts
    • often injured
  26. What are the 3 parts of the lateral ligament?
    • anterior talofibular lig (weak)
    • posterior talofibular (strong)
    • calcaneofibular (vertical)
  27. What arches are maintained but the shape of bones, their relation to one another, and plantar fascia?
    • medial longitudinal arch
    • lateral longitudinal arch
    • transverse arch
  28. What are the characteristics of the medial longitudinal arch?
    • along medial border
    • from calcaneus to metatarsals 1-3
    • absorbs shock (depresses during WBing)
    • recoils when weight is removed
    • can see pes cavus and planus
  29. What are the characteristics of the lateral longitudinal arch?
    • anterior part of calcaneus to metatarsals 4-5 and cubiod
    • in contact with floor when standing (usually)
  30. What are the characteristics of the transverse arch?
    • side to side
    • through cuneiforms and cuboid
  31. What is a high arch called?
    pes cavus
  32. What is a low arch/flat feet called?
    pes planus
  33. What is another name for spring lig, and what are its characteristics?
    • calcaneonavicular lig
    • goes from calcaneus to navicular
    • short but wide
    • supports medial side of longitudinal arch
  34. What ligament contains a long and short one, and supports the lateral longitudinal arch?
    plantar lig
  35. What are the characteristics of the plantar aponeurosis (fascia)?
    • goes from calcaneus to proximal phalanges along bottom of foot
    • keeps posterior part from separating from back of foot
    • "plantar fasciitis"
  36. What bones make up the hindfoot?
    • calcaneus and talus
    • contacts ground first in gait, influences rest of foot
  37. What bones make up the midfoot?
    • navicular, cuboid and cuneiforms
    • provides stabilty and mobility
  38. What bones make up the forefoot?
    • metatarsals and phalanges
    • adapts to level ground
  39. What occurs at the foot when the distal segment of the calcaneus is directed aay from the midline?
    • calcaneal valgus
    • pronated foot (collapse on arches)
  40. What occurs at the foot when the distal segment of the calcaneus is directed toward the midline?
    calcaneal varus
