Arthrology: Ankle and Foot

Question 1

Distal tibiofibular joint type

Answer 1

syndesmosis/plane/gliding

Question 2

Talocrural joint type

Answer 2

Hinge

Talus is WB structure

Question 3

Talocrural morphology

Answer 3

Talus = convex
Distal tibia = concave

Question 4

talocrural open chain DF arthrokinematics

Answer 4

posterior glide of talus and gapping of syndesmosis

fibula glides anterior

Question 5

talocrural open chain PF arthrokinematics

Answer 5

anterior glide of talus and closing of syndesmosis

fibula glides posterior

Question 6

High ankle sprain

Answer 6

DF/rotation/eversion mechanism

Hyper DF

Question 7

Subtalar joint type

Answer 7

planar

talonavicular joint
talocalcaneal joint

Question 8

subtalar morphology

Answer 8

anterior/middle facets of calcaneus:
- talus = convex
- calcaneus + navicular = concave

posterior facet of calcaneus:
- talus = concave
- calcaneus = convex
