In the Nucleoplasty procedure, the physician removes tissue and applies controlled levels of thermal energy (heat) to the disc. Nucleoplasty is usually performed on an outpatient basis. Local anesthesia and mild sedation may be used to reduce discomfort during the procedure. You will be awake to enable you to provide important feedback to the physician. With the guidance of X-ray images, your physician will first advance a needle into the disc. A specialized device, known as a Perc-D™ SpineWand™, will then be introduced through the needle and into the disc. Nucleoplasty consists of creating a series of channels in your disc and then thermally treating the tissue immediately adjacent to the Perc-D SpineWand. Small amounts of radio wave energy are released into the damaged disc through the Perc-D SpineWand that is about the thickness of a dime. The energy creates a molecular reaction that causes some of the spongy tissue inside the damaged disc to dissolve. As pressure inside the disc is reduced, the herniation in the shell retracts, the irritation to the nearby nerve roots is reduced, and pain is relieved. The procedure should take less than an hour.
