Description[edit | edit source]

The Peroneus Tertius muscle also called the Fibularis Tertius is one the 3 peroneal muscles (peroneus longus, peroneus brevis).[1] It is absent in 5% to 17% of the human white population.[2]

Origin[edit | edit source]

Distal half or third of the fibula.[3]

Insertion[edit | edit source]

Base of the 5th metatarsal.[3]

Nerve[edit | edit source]

Deep peroneal nerve.[1]

Function[edit | edit source]

Secondary function in foot dorsiflexion and eversion.[3]

Clinical relevance[edit | edit source]

The strength of eversion and dorsiflexion is not compromised in people who lack the Peroneus Tertius muscle. Peroneus Tertius seems to not provide higher protection against ankle ligamentous injury.[2]
