| Latin: | compartimentum cruris laterale |
| Artery: | Fibular artery |
| Nerve: | Superficial fibular nerve |
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.
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 |
The lateral compartment of the leg is supplied by the superficial fibular nerve (superficial peroneal nerve).
Its proximal and distal arterial supply consists of perforating branches of the anterior tibial artery and fibular artery.[2]
