The Racz Catheter Procedure (Epidural Neurolysis) is used to release some of the scar tissue from around entrapped nerves in the epidural space of the spine, so that medications such as cortisone can reach the affected areas. It is used to decrease the pain caused by the scarring. This procedure is named for the physician who pioneered it, Dr. Gabor Racz.
