Sheets of connective tissue called fascia are located under the skin of the arms and legs. These wrap around groups of muscles, nerves, and blood vessels to create a unit called a compartment. When pressure builds up in these enclosed spaces, it is redirected into the compartment. When pressure reaches a certain point, it disrupts blood flow. Blood vessels may fail and tissue dies. Acute compartment syndrome (ACS) can affect the arms, hands, legs, feet, and buttocks.
