Fasciotomy is a surgical procedure that cuts away the fascia, the tissue around the outside of a muscle, to relieve tension or pressure. It will often times vary in thickness, composition, density, and elasticity, depending on which muscle of the body it is covering. Even though it may sound similar to a ligament or tendon, it is in fact, much different. The fascia is commonly injured through continuous strain or some type of severe trauma to the forearm.
