Lateral compartment of leg
Encyclopedia
The lateral compartment of the leg is supplied by the superficial fibular nerve
.
Its proximal and distal arterial supply consists of perforating branches of the anterior tibial artery
and fibular artery
.
It contains the evertors of the foot (fibularis longus
, fibularis brevis
). These muscles also are involved in plantarflexion
.
Superficial fibular nerve
The superficial fibular nerve innervates the fibularis longus and fibularis brevis muscles and the skin over the greater part of the dorsum of the foot .It passes forward between the fibularis muscles and the extensor digitorum longus, pierces the deep...
