Lateral compartment of the leg

Dr Craig Hacking et al.

The lateral compartment of the leg, also know as the peroneal compartment, is one of the four compartments in the leg between the knee and foot. Muscles within this compartment primarily produce ankle and foot eversion.

The leg is separated into anterior, lateral, superficial posterior and deep posterior compartments by intermuscular septa and surrounded by the deep fascia of the leg.
