PERCUTANEOUS DISC NUCLEOPLASTY

This minimally invasive procedure uses a small needle and advanced radiofrequency technology to reduce a herniated disc, quickly relieving pain in most patients. The procedure is performed on an outpatient basis using IV sedation and local anesthesia.

Cannula Inserted

After local anesthetic is injected to numb the area, a thin needle called a cannula is inserted into the herniated disc. The doctor uses x ray images to guide the placement of the cannula.

Disc Nucleus Treated

A radiofrequency probe is carefully inserted through the cannula and into the disc. The device sends pulses of radio waves to dissolve small portions of the disc nucleus. Because only enough of the disc is removed to reduce the pressure inside the disc, the spine remains stable.

Herniation Relieved

The empty space created by the probe allows the disc to reabsorb the herniation.

End of Procedure

The probe and needle are removed, and the insertion area in the skin is covered with a small bandage. Because no muscles or bone are cut during the procedure, recovery is fast an there is no scar. The patient may need a day of bed rest after the procedure, as well as physical therapy. Most may return to normal activity within one to six weeks.
