Chronic exertional compartment syndrome as a cause of anterolateral leg pain

Exercise-induced leg pain (ELP) and tightness may be caused by a chronic exertional compartment syndrome (CECS). Although CECS can develop in any muscle compartment, most individuals suffer from an anterior tibial muscle CECS (ant-CECS). Typically, a patient with ant-CECS experiences discomfort toward the end of sports activity or in the hours thereafter. Physical examination may reveal tenderness upon palpation of the anterior tibial muscle belly. The gold standard diagnostic tool is a dynamic intracompartmental pressure (ICP) measurement demonstrating elevated muscle tissue pressures. Duplex analysis and imaging may be indicated for exclusion of concomitant entities such as entrapment of the popliteal artery or nerves. Conservative treatments including modification of the patient's running technique can be successful. A fasciotomy must be considered in recalcitrant cases. Residual or recurrent disease may necessitate partial removal of the fascia. The aim of this overview is to discuss the management of CECS in the anterolateral portion of the leg.
