The thin fibula is located posterolateral to the tibia and serves mainly for muscle fixation. It has no weight bearing function. It articulates with the tibia (proximally and distally) and the talus distally.

Proximal Epiphysis

 Fibula Head & #8211; irregular shape

 Articular Face for the Tibia & #8211; flat face that articulates with the lateral tibial condyle

Distal Epiphysis

 Lateral Malleolus - Distal fibular expansion

 Articular Face for Talus

Body (Diaphysis)

 Anterior Edge & #8211; thick and rough

 Interosseous Edge & #8211; interosseous crest

 Back Edge & #8211; begins at the apex and ends at the posterior edge of the lateral malleolus

 Medial Face & #8211; narrow and flat. It is the interval between the anterior and interosseous borders.

 Side Face & #8211; it is convex and is located between the anterior and posterior borders

 Back Face & #8211; between the posterior and interosseous borders

THE Fibula hinges with two bones: Tibia and Talus.
