Disc hernia can cause a pain when nerve or spinal cord is pinched. Percutaneous Disc Nucleoplasty is performed to reduce a herniated disc pressure and provides quick relief for most patients. It uses a small needle and modern radiofrequency technology. Percutaneous Disc Nucleoplasty is performed on outpatient basis and uses relaxing medication as well as local anesthetic to numb the skin.

A thin needle called cannula is inserted into herniated disc. The physician uses a fluoroscope to ensure right position of cannula.

A small catheter-like device is inserted into the disc and sends radio pulses to dissolve small portions of disc nucleus. The spine remains stable. The empty space draws the disc wall back in the needle and device is removed and a small bandage is applied on insertion area. After Percutaneous Disc Nucleoplasty the patient may required a day of bed rest.
