Flashcards in Ankle Joint Deck (30):
1

How do the phalanges of the hallux differ from the other phalanges?

There are only 2 cf to 3

1

What are the borders of the talocrural joint?

Medial and lateral malleoli

Inferior transverse ligament posteriorly

1

What type of joints are the TCN and subtalar joint?

Ball and socket

2

What is another name for the great toe?

Hallux

3

Which bones make up the TCN and subtalar joint?

The talus

Calcaneus

Navicular

 

4

Which bones are joined in the Lisfranc joint?

Tarsal and metatarsal

5

Why is the second metatarsal the most common to be fractured?

It's the longest and thinnest

The base is wedged between its adjacent bones

6

What attaches to the tibial tuberosity?

The patellar tendon

7

Is the foot in inversion or eversion when running?

Eversion

8

What type of joint is the superior tibiofibular joint?

Synovial

8

Why is the axis of movement at the ankle joint oblique?

Because the lateral malleolus is longer

9

What does the plantar aponeurosis joint?

The calcaneus and the metatarsal heads

10

How many arches are there in the foot?

3 - 2 longitudinal, 1 transverse

12

What type of joint is the inferior tibiofibular joint?

Fibrous

13

Why is the ankle more stable in dorsiflexion?

Because the articular surface of the talus is wider anteriorly - therefore wedges into the joint more

15

What is the name of the structure formed by the inferior tibiofibular joint?

Malleolar mortise

16

Why does swelling spread anterior in the ankle joint?

Because the capsule attaches fairly anterior on the neck of the talus

16

What is the sinus tarsi?

A gap between the subtalar and TCN joint - the interosseous ligament runs between it and the run supply of the talus

18

What are the important boney structures at the head of the tibia?

The lateral and medial condyles

The intercondylar eminence

20

What movement occurs at the talocrural joint?

Dorsi and plantar flexion

21

What are the ligaments of the medial aspect of the ankle joint?

The deltoid ligament

The plantar calcaneonavicular ligament aka spring ligament

22

What are the names of the ligaments that stabilise the superior tibiofibular joint?

Anterior and posterior tibiofibular ligaments

 

23

Which tarsal is the most important in the ankle joint?

The talus

24

Why is the talus susceptible to necrosis?

It doesn't receive blood for muscle as none attach to it

If the neck of the talus is broken it can lose blood supply

25

Which ligament is most commonly damaged in a inversion sprain?

Lateral collateral ligaments - particularly the anterior talofibular ligament

26

At which joints does inversion and eversion of the foot occur?

TCN and subtalar joint

27

Why is the fibula so vascular?

The many muscle attachments provide their blood supply

28

What malleolus extends more distal?

Lateral

29

Where do you find the soleal line? How does it appear?

Post. aspect of the tibia

Runs inferio-medially from the proximal tibial-fibula joint

30

What are tarsal bones?

Talus

Calcaneus

Cuboid

Navicular

3x Cuneiform
