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]
