Fibula (left) (Fibula)
Educational content only — not medical advice.
Anatomy
A slender bone running alongside the tibia on the lateral side. It does not participate directly in the knee joint itself, but its proximal head articulates with the tibia (proximal tibiofibular joint) and anchors ligaments and muscles.
Clinical notes
A fibular neck fracture may accompany common peroneal nerve injury, causing foot drop, and an avulsion fracture of the fibular head relates to biceps femoris traction and lateral collateral ligament injury. The fibula is also a common bone-graft source (free vascularized fibular flap, e.g. for mandible reconstruction), as most of it can be harvested without impairing walking.
