Fibula

Question 1

What is the main function of the fibula?

Answer 1

Attachment of muscles

It is non weight bearing.

Question 2

What are the articulations of the fibula?

Answer 2

The ankle joint

Proximal and distal tibiofibular joints

Question 3

The fibula has how many ossification centers?

Answer 3

3:
Primary shaft
Secondary distal and proximal ends

Question 4

Usually, fractures to the tibia and fibula have ____ ______, and the unaffected bone can act as a ____.

Answer 4

Minimal displacement

Splint

Question 5

Fractures to what structures occur in contact sports on hard surfaces?

Answer 5

Medial and/or lateral malleoli

Question 6

Which leg bones are good sources for bone grafting?

Answer 6

Both tibia and fibula

Question 7

Where are the common sites of fibial fractures?

Answer 7

proximal to lateral malleolus

distal to head of the bone

Question 8

How can fibial fractures be dangerous?

Answer 8

if the fracture is below the head (proximal bone), there may be damage to the common fibular nerve. This may cause atrophy and paralysis to the anterior and lateral leg muscles

Question 9

Why are fibial fractures very painful?

Answer 9

the fracture disrupts the musculature attachments

Question 10

Why might a fibial fracture affect locomotion?

Answer 10

the fibia acts to stabilize the ankle joint, so a fracture may reduce this stabilization
