This treatment is prescribed by your doctor. It is not for everyone. Please talk with your doctor and see if it is right for you. Your doctor should discuss all potential benefits and risks with you. Although many patients benefit from the use of this treatment, approximately half of the patients who received the X-STOP device in the 2-year study experienced a degree of pain relief and ability to increase their activity levels that was sufficient to be considered a successful outcome at 2 years after surgery. This compares with the control group treated with non-surgical care that had a 6% successful outcome treatment success rate.15
