Q

What is the joint classification of the talocrural joint?

A

Uniaxial hinge synovial

17
Q

What is the closed packed position of the talocrural joint?

A

Full Dorsi flexion

18
Q

What ligaments are at the talocrural joint?

A

Medial collateral/deltoid ligament ( 4 bands)-limit valgus strain, stronger then lateral
Lateral collateral ( 3 bands) -limits varus strain( anterior talofibular is the most commonly injured)

19
Q

What is the joint classification of the subtalar joint?

A

Uniaxial hinge synovial

20
Q

What is the closed packed position of the subtalar joint?

A

Supination

21
Q

Explain the difference between the talocrural and the subtalar joint?

A

Talocrural is the talus articulating with the distal tibia/tibia
The subtalar is the talus articulating with the calcaneus

22
Q

The talocalcaneal joint is composed of what two functional joints within the capsule?

A

Talocalcaneal- talus and calcaneus
Talonavicular-talus and navicular
