The fibularis brevis is a muscle in the lateral compartment of the leg. It is located deep to the fibularis longus.

  • Attachments:
    • Originates from the inferolateral surface of the fibular shaft. The muscle belly forms a tendon, which descends with the fibularis longus into the foot.
    • It travels posteriorly to the lateral malleolus, passing over the calcaneus and the cuboidal bones.
    • The tendon then attaches to a tubercle on the 5th metatarsal.
  • Actions: Eversion of the foot.
  • Innervation: Superficial fibular (peroneal) nerve.
  • Blood supply: Fibular artery.
