The lateral compartment of the leg is a fascial compartment of the lower leg. It contains muscles which make eversion and plantarflexion of the foot.
Muscles
[edit]The lateral compartment of the leg contains:
| Image | Muscle | Origin | Insertion | Innervation | Main Action |
|---|---|---|---|---|---|
|
Fibularis longus | Head and superior two thirds of lateral surface of fibula | Base of 1st metatarsal and medial cuneiform | Superficial fibular nerve (L5, S1, S2) |
Everts foot and weakly plantarflexes ankle |
|
Fibularis brevis | Inferior two thirds of lateral surface of fibula | Dorsal surface of tuberosity on lateral side of base of 5th metatarsal |
Action
[edit]- Foot evertors
- Foot plantarflexion
Nerve supply
[edit]The lateral compartment of the leg is supplied by the superficial fibular nerve (superficial peroneal nerve).
Blood supply
[edit]Its proximal and distal arterial supply consists of perforating branches of the anterior tibial artery and fibular artery.[3]
