The fibularis muscles (also called peroneus muscles or peroneals) are a group of muscles in the lower leg.
Description
The muscle group is normally composed of three muscles: fibularis longus, fibularis brevis, and fibularis tertius.[1]
The fibularis longus and fibularis brevis are located in the
dorsiflexion
).
| Name | Compartment | Action | Nerve | Artery |
| Fibularis longus | lateral compartment |

superficial fibular nerve | fibular artery |
| Fibularis brevis | lateral compartment | eversion and plantar flexion | superficial fibular nerve | fibular artery |
| Fibularis tertius | anterior compartment | eversion and dorsiflexion |
deep fibular nerve | anterior tibial artery |
The fibularis muscles are highly variable. Several variants are occasionally present, including the peroneus digiti minimi and the peroneus quartus.[2] The quartus is more closely associated with the tendons of the extensor digitorum longus and may send a small tendon to the fifth toe.[3]
Nomenclature
Terminologia Anatomica designates "fibularis" as the preferred word over "peroneus".[4]
