Disc decompressions are used to treat patients with pain coming from a herniated disc. A wand is introduced through a needle and placed into the center of the disc where a series of channels are created to remove tissue from the nucleus. Tissue removal from the nucleus acts to decompress the disc and relieve the pressure exerted by the disc on the nearby nerve root. As pressure is relieved the patients pain is reduced. Typically a percutaneous discectomy takes about 30 minutes, and the patient is able to leave shortly afterwards, with only a small bandage over the needle insertion site. This procedure is many times used for patients with back and leg pain symptoms including sciatica and radiculopathy. It is also a exceptional treatment for patients with small contained herniations for whom open surgical discectomy may not be indicated or necessary.
