This document provides a review of compartment syndrome. It begins by defining compartment syndrome as an increase in compartment pressure within an osteofascial compartment, most commonly caused by crush injuries or fractures to the lower extremities. It then discusses the anatomy of the leg and foot compartments, clinical presentation of compartment syndrome, methods for measuring compartment pressure, and surgical treatment via fasciotomy. The key points are that compartment syndrome must be diagnosed promptly to prevent tissue damage, and is treated with surgical release of the fascial compartments to reduce pressure.
