It is one of the four compartments, with the others being the [[anterior compartment of leg|anterior]], [[posterior compartment of leg|superficial posterior]], and [[deep posterior compartment of leg|deep posterior]] compartments. The lateral compartment is primarily involved in the eversion and plantarflexion of the [[foot]].

==Anatomy==
The lateral compartment of the leg is bounded by the [[anterior intermuscular septum]] of the leg anteriorly, the [[posterior intermuscular septum]] of the leg posteriorly, the [[fibula]] laterally, and the [[tibia]] and [[interosseous membrane]] medially. It is enclosed by the deep [[fascia]] of the leg, known as the crural fascia.

===Muscles===
The lateral compartment contains two important muscles:
* The [[peroneus longus]] (also known as fibularis longus) - starts from the head and upper body of the fibula and inserts into the first metatarsal and medial cuneiform bones of the foot. It is responsible for plantarflexion and eversion of the foot.
* The [[peroneus brevis]] (also known as fibularis brevis) - originates from the lower two-thirds of the fibula and inserts into the base of the 5th metatarsal. It also aids in plantarflexion and eversion of the foot.

===Nerve Supply===
The muscles in the lateral compartment are innervated by the [[superficial peroneal nerve]] (also known as the superficial fibular nerve), which is a branch of the [[common peroneal nerve]].

===Blood Supply===
Blood supply to the lateral compartment is primarily through branches of the [[peroneal artery]], which is a branch of the [[posterior tibial artery]].

==Function==
The primary function of the lateral compartment muscles is to evert the foot, which helps in stabilizing the foot during walking or running on uneven surfaces. They also assist in plantarflexion, which is the downward movement of the foot away from the leg, important in the push-off phase of gait.

==Clinical Significance==
Compartment syndrome, a condition where increased pressure within one of the leg's compartments causes decreased blood supply to the area, can occur in the lateral compartment. Symptoms may include severe pain, swelling, and decreased function of the affected compartment. This condition requires immediate medical attention to prevent permanent damage.
