Anterior compartment

Anterior Compartment refers to one of the sections into which the body or a body part is divided. In the context of human anatomy, the term is often used to describe areas of the lower leg and forearm.

Anatomy

The anatomy of the anterior compartment varies depending on the body part in question. In the lower leg, the anterior compartment contains muscles such as the tibialis anterior, extensor hallucis longus, extensor digitorum longus, and peroneus tertius. These muscles are primarily responsible for dorsiflexion and inversion of the foot.

In the forearm, the anterior compartment contains several muscles that are involved in flexion of the wrist and fingers, as well as pronation of the forearm. These include the flexor carpi radialis, flexor carpi ulnaris, palmaris longus, and flexor digitorum superficialis.

Clinical Significance

The anterior compartment is clinically significant due to its susceptibility to compartment syndrome. This is a condition in which increased pressure within one of the body's compartments results in insufficient blood supply to tissue within that space. Symptoms can include severe pain, weakness, numbness, and potential muscle and nerve damage.

Treatment

Treatment for anterior compartment syndrome typically involves surgery to relieve the pressure, known as a fasciotomy. In some cases, physical therapy may also be necessary to restore function and strength to the affected area.
