How it works

Back and leg pain from lumbar spinal stenosis (LSS) occurs when the space between the vertebrae is reduced, causing bone or tissue to come in contact with the spinal nerve. Most people with LSS get relief from pain when they bend forward or sit down. That's because this position opens the space around the pinched nerve. The X-STOP Spacer uses this principle and can provide sustained relief—even when you stand up straight and walk.

Lifting the pressure off of pinched nerves relieves pain

The X-STOP Spacer is a small implant that fits between two bones in the back of your spine—at the level of the pinched nerve. You can feel these bones, called the spinous processes, when you run your fingers down your spine. Once in place, the X-STOP Spacer can lift the vertebra off the pinched nerve. Learn more about your spine and the causes of nerve damage.

Sustained pain relief—even when you stand and walk

The unique X-STOP Spacer is designed to stay safely and permanently in place without being attached to bone or ligaments, by screws or other hardware, and there's no fusion involved. It works with your spinal anatomy to keep the space around the nerve open—and can relieve your pain and other symptoms—even when you stand up straight and walk. With the X-STOP Spacer you should not need to bend forward to relieve your symptoms.

The X-STOP Spacer may relieve the kinds of pain and discomfort caused by LSS:

  • Dull or aching back pain that travels to your legs
  • Numbness and a pins-and-needles sensation in your legs, calves, or buttocks
The X-STOP Spacer works with your anatomy to stay in place. Unlike other spine surgeries, nothing is attached to bone or ligament and the procedure does not result in spinal fusion.

Short recovery and rapid pain relief

The X-STOP Spacer is implanted during a short procedure—typically 45 to 90 minutes. In some patients, it can be performed on an outpatient basis and with local anesthesia. This is an especially important benefit for people who should avoid general anesthesia due to their age or other health conditions. You and your surgeon will decide what's best for you.

The X-STOP procedure is minimally invasive. It’s not like traditional surgery, such as a laminectomy, which removes structurally important bone (lamina) and tissue (ligaments that connect the vertebrae). The X-STOP Spacer preserves your anatomy and your spinal stability. That’s why it may offer a short recovery time and a low complication rate.16 And the spacer is not positioned close to nerves or the spinal column, but rather behind the spinal cord between the spinous processes.

Major surgery, like a laminectomy, removes parts of your vertebrae and ligaments that protect and stabilize your spine. The X-STOP procedure preserves your spinal anatomy. Learn more about major surgeries.

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
