Review of Compartment Syndrome

Abstract

Compartment syndrome is a painful condition, caused by increased pressure in a closed muscular compartment. A compartment is a group of muscles enclosed in fascia and septa of connective tissue, which separates different muscle groups. The chambers created receive their blood supply through the arteries. As the pressure builds in the closed space, the blood supply to muscles enclosed decreases. Normal compartment pressure allows blood to flow in and then venous outflow to exit the compartment. However, with increased pressure in the compartment, the arterial flow is impaired. Subsequently, venous outflow stops, adding to the volume of the closed chamber, and hence, pressure builds to the point when the arterial flow stops as well. This chapter provides a general overview of the compartment syndrome in orthopaedic surgical practice. It includes definitions, causes, microscopic anatomy and pathophysiology, as well as the management of this condition.
