Anatomy study note · Lower limb

Fibula

The slender lateral bone of the leg. It carries no body weight and takes no part in the knee joint but forms part of the ankle joint and gives attachment to muscles.

Key points

• Not weight-bearing; not in the knee joint.
• Lateral malleolus = part of the ankle mortise.
• Neck → common fibular nerve → footdrop.
• Shaft: primary centre; ends: secondary centres; growth at the epiphyseal plate.
• Limb bones: limb-bud mesenchyme, endochondral (except clavicle).
• Long bone: endochondral ossification; epiphyseal plate closes ~20 y.
• Bone: type I collagen + hydroxyapatite.
