Fibula

Os fibulae

The fibula is a thin bone lateral to the tibia, connected by the interosseous membrane. The fibular head articulates with the lateral tibial condyle. The lateral malleolus at the distal end extends further inferiorly than the medial malleolus, contributing to ankle stability.

Type Bone
Body System Skeletal
Body Region Leg
Latin Name Os fibulae
FMA ID 24479

Function

The slender lateral bone of the leg. While it bears minimal weight, it provides attachment for muscles and ligaments and forms part of the ankle joint. The lateral malleolus stabilizes the ankle laterally.

Clinical Significance

Lateral malleolus fractures are the most common ankle fractures. Weber classification categorizes ankle fractures based on fibular fracture level relative to the syndesmosis. The fibula is commonly used as a bone graft donor site.
