Increased interstitial pressure in a closed, nonexpanding, myofascial compartment that compromises the function of the blood vessels, muscle and nerves.
Acute Compartment Syndrome – Causes includes, but not limited to fractures and crush injuries. Results in ischemia and eventual necrosis of muscles and/or nerves. It is medical emergency
Chronic/Exertional Compartment Syndrome – Can occurs in distance runners or those involved in major changes in activities levels. Leads to ischemia, pain, and rarely neurological signs and symptoms can be present. Symptoms are less sever, and tend to improve with rest, but may proceed to acute compartment syndrome if the exercise continues, because fascia cannot accommodate the hypertrophy in the specific area.
