Unit 5 - Lower Limb: Tibiofibular Joints (Ex. IV)

Question 1

What are the articulations of the proximal tibiofibular joint?

Answer 1

fibular head and articular facet of L tibial condyle

Question 2

What ligaments secure the proximal tibiofibular joint?

Answer 2

A and P ligaments of the fibular head

Question 3

What type of joint is the distal tibiofibular joint?

Answer 3

syndesmosis

Question 4

What does the distal tibiofibular joint create?

Answer 4

mortise formed by the M and L malleoli that cup the talus and stabilize the ankle joint

Question 5

What is the main support of the distal tibiofibular joint?

Answer 5

deep interosseous tbiofibular ligament –> continuous w/ interosseous membrane of the leg

Question 6

What are the ligaments of the distal tibiofibular joint?

Answer 6

deep interosseous tibiofibular ligament

external A and P tibiofibular ligaments

Question 7

What is the function of the interosseous membrane?

Answer 7

unites shafts of tibia and fibula

provides stability to the distal tibiofibular and ankle joints
