What is the definition or description of: fasciotomy?

Surgical procedure: Muscles are surrounded by connective tissue known as fascia and is particularly dense in the arms and legs. When the underlying muscle is injured, due to infection or blood clot, it will swell. If the swelling is severe, the fascia works as a tourniquet and can reduce the blood flow to the muscle leading to more damage. Fasciotomy is a procedure that cuts open the fascia and relives pressure.

Fasciotomy: Fasciotomy or fasciectomy is a surgical procedure where the fascia is cut to relieve tension or pressure commonly to treat the resulting loss of circulation to an area of tissue or muscle. Fasciotomy is a limb-saving procedure when used to treat acute compartment syndrome. The most common side effect of fasciotomy is accidental damage to a nearby nerve.
