The X STOP® Spacer

X STOP® is a nonfusion surgical implant for use in treating lumbar spinal stenosis. Lumbar spinal stenosis can cause pain and may limit physical function. X STOP® is a titanium alloy device implanted between the spinous processes to relieve symptoms from low back spinal stenosis. The spinous processes are small stubby finger-like bones that slightly protrude off the back of each vertebral body.

X STOP® Procedure
The X STOP® device is used in a procedure called the X STOP® Interspinous Process Decompression System (IPD®). IPD® is a surgical procedure. During the procedure, the X STOP® device is implanted between the spinous processes using fluoroscopic guidance (a type of x-ray). The X STOP® device may be implanted at one or two levels of the lumbar spine.

The procedure is performed under local anesthesia with the patient positioned on their side. The surgery takes between 45 minutes to an hour-and-a-half.
