Question 15

What flexion does tibiotalar joint allow

Answer 15

Dosiflextion
Platar flexion

Question 16

Subtalar joint

Answer 16

Allows Inversion (medially) and eversion (laterally)

Question 17

Ligemsnt that help over movement of joints in the foot

Answer 17

Anteriror talofibular ligament ATFL - resists eversion during plantar flexion. Most commonly sprained ligament
Posterior talofibular ligament - prevents posterior translation of foot on tibia. Strongest ligament
Calcaneofibular (CFL) - limits inversion in neutral or dorsiflexion
Deltoid ligament - medial ankle ligament. limits eversion of ankle joint
