Percutaneous intradiscal radiofrequency treatment of the intervertebral disc nucleus for low back pain

The condition

If the tough outer cover of a disc that acts as a cushion between 2 bones in the lower part of spine (the lumbar vertebrae) tears, the soft centre can bulge through the tear. This is called herniation, or a slipped disc. If it presses on a nerve, the slipped disc can cause pain in the back, pain in the legs (sciatica), numbness or weakness in the legs, or even problems with the bladder.

Treatments include painkillers, drugs to reduce inflammation, corticosteroid injections into the affected area, physical therapy and acupuncture. If the symptoms are severe or long lasting, the bulging part of the disc may be removed, either by open surgery or using less invasive techniques. This is called discectomy.

NICE has looked at using percutaneous intradiscal radiofrequency treatment of the intervertebral disc nucleus for low back pain as another treatment option if the pain hasn't responded to treatment and open surgery is not suitable.

NHS Choices and NICE's information for the public about low back pain may be a good place to find out more.
