The tibiofibular joints

Question 1

What is the tibiofibular joint

Answer 1

Two articulations between the fibula and tibia of the leg.
Comprised of the proximal tibiofibular joint- synovial plane
and distal tibiofibular joint- fibrous joint

Question 2

What are the supporting structures of the proximal tibiofibular joint?

Answer 2

Joint capsule
Anterior and posterior superior tibiofibular ligaments
Lateral collateral ligaments of the knee joint
Biceps femoris

Question 3

What is the arterial supply of the proximal tibiofibular joint?

What is the nervous supply?

Answer 3

Inferior genicular arteries

Branchees of common fibular nerve

Question 4

What are the supporting structures of the distal tibiofibular joint?

Answer 4

interosseous membrane
Anterior and posterior tibiofibular ligaments
Inferior transverse tibiofibular ligament

Question 5

What is the arterial supply of the distal tibiofibular joint?

What is the nervous supply?

Why doesn’t the distal tibiofibular joint have a joint capsule?

Answer 5

Fibular artery

Deep peroneal and tibial nerves

As it is a fibrous joints and only synovial joints have joint capsules
