Fibula

Question 1

Anatomical location

Answer 1

Makes up one of the two bones of the leg

Found laterally to the tibia

Question 2

Function

Answer 2

To act as an attachment for muscles (not weight bearing)

Question 3

Proximal fibula

Answer 3

Enlarged head, contains facet for articulation with lateral condyle of tibia
Common fibular nerve can be found on the posterior lateral surface of the fibular neck

Question 4

Fibular shaft

Answer 4

3 surfaces (anterior, lateral, posterior) 
Leg is split into 3 compartments, each surface faces respective compartment

Question 5

Distal fibula

Answer 5

Lateral malleolus - continuation of lateral surface

More prominent than medial malleolus and can be palpated at ankle on lateral leg

Question 6

Fibular fractures

Answer 6

Lateral malleolus prone to fracture

• Forced external rotation - force of talus against lateral malleolus causes a spiral fracture
• Foot being twisted outwards (eversion) - talus presses against lateral malleolus, causes transverse fracture
