Arthrokinematics Of The Hip And Lower Extremity

Question 1

Coxofemoral Arthrokinemetics

Answer 1

-Convex femoral head moves on concave acetabulum in open kinetic chain
-Roll and glide in opposite directions

-Concave acetabulum moves on convex femoral head in closed kinetic chain
-Roll and glide in same direction

Question 2

Tibiofemoral Arthrokinematics

Answer 2

-Concave tibial plateaus move on convex femoral condyles in open kinetic chain
-Roll and glide in same direction

-Convex femoral condyles move on concave tibial plateaus

Question 3

Talocrural Dorsiflexion And Plantarflexion

Answer 3

-Convex talar dome moves on stationary concave distal tibia in open kinetic chain
-Roll and glide in opposite directions

-Concave distal tibia moves on stationary convex talus
-Roll and glide in same direction

Question 4

Subtalar And Talocalcaneal Arthrokinematics

Answer 4

-Concave talus moves over convex calcaneus
in closed kinetic chain
-Roll and glide in same direction

-Convex calcaneus moves on concave talus in open kinetic chain
-Roll and glide in opposite directions

Question 5

Talonavicular arthrokinematic

Answer 5

-Concave proximal navicular moves on convex talar head in open kinetic chain
-Roll and glide in same direction

-Convex talar head moves on concave proximal navicular in closed kinetic chain
-Roll and glide in opposite direction

Question 6

Metatarsophalangeal Arthrokinematics

Answer 6
