The lateral compartment of the leg contains:

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



Nerve Supply

The lateral compartment of the leg is supplied by the superficial fibular nerve (superficial peroneal nerve).

Blood Supply

Its proximal and distal arterial supply consists of perforating branches of the anterior tibial artery and fibular artery.[3]
