Question 5

How many surfaces of calcaneum?

Answer 5

6 surfaces

2.Posterior - attachment to tendocalaneous (Achilles tendon)
Forms prominence of heel
3.Superior surface - with talus by 2 articular surfaces separated by a rough groove sulcus calcanei
4. Inferior surface
5. Medial surface - sustentaculum tali (supports talus)
6. Lateral surface - peroneal tubercle

Question 6

Answer 9

5th

Question 10

Calcaneum articulates above with ______
And in front with _____?

Answer 10

Above with talus
In front with cuboid

Question 11

Medial surface of calcaneum has what process?

Answer 11

A large shelf-like process
Sustentaculum tali
Which assist in support of talus

Question 12

The lateral surface of calcaneum has what?

Answer 12

A small elevation called peroneal tubercle

Question 13

What is the purpose of peroneal tubercle on lateral surface of calcaneum?

Answer 13

Separates the tendons of fibularis longus and brevis

Question 14

Talus bone has ligaments attachment but no attachment for?

Answer 14

Muscles and tendons

Question 15

A deep grove is present in the neck of talus called?

Answer 15

salcus tali

Question 16

The head of talus articulates with which hone?

Answer 16

Navicular

Question 17

The tuberosity of navicular attaches to which tendon?

Answer 17

Tibialis posterior tendon

Question 18

Cuboid has attachment for?

Answer 18

Peroneus (fibularis) longus muscle

Question 19

The wedge shape of cuneiform bone contribute to the formation and maintanence of?

Answer 19

Transverse arch of foot

Question 20

Which metatarsal has a prominent tubercle and for what?

Answer 20

5th metatarsal has a prominent tubercle at its base
Provides attachment to peroneus (fibularis) brevis tendon

Question 21

What are the joints formed by talus?

Answer 21

1.ankle joint/talocrural
superiorly between talus and bones of leg (tibia and fibula)

2. Subtalar joint
   Inferiorly between talus and calcaneus
3. Talonavicular joint
   Anteriorly between talus and navicular

Question 22

Talus has a risk of ?

Answer 22

Avascular necrosis as vascular supply is dependent on fascial structures

Question 23

The posterior surface of talus has 2 tubercles for attachment of?

Answer 23

Flexor hallucis longus tendon

Question 24

What are tallus fracture?

Answer 24

neck
Most common
Foot forcibly dorsiflexed
Avascular necrosis of talus

Body
Jumping from height

Question 25

What is calcaneum fracture?

Answer 25

Fall from height
Talus forces downward into calcaneum so calcaneum becomes wider laterally

Sustentaculum tali can be fractured by forced inversion of foot

Question 26

What are metatarsal fracture?

Answer 26

Due to forced inversion of foot
Fibularis brevis pulls off the base of 5th metatarsal
