X-Stop is a minimally invasive spinal surgery procedure that may be performed to treat cases of lumbar spinal stenosis that don’t respond to more conservative treatments, such as physical therapy and medication. X-Stop is also the name of the titanium implant used in the procedure, a device in a category termed “Interspinous Process Decompression Systems.” This lumbar spinal surgery procedure was approved as safe and effective by the FDA in 2005.
Lumbar spinal stenosis is an unnatural narrowing of the spinal column in the lower, or lumbar portion of the spine. The constricted spinal canal that characterizes spinal stenosis puts pressure on the spinal cord and the nerves emanating from it at the affected vertebrae, which can cause pain and restrict mobility. In the X-Stop procedure, the titanium implant is inserted into the spine through a small incision made between two spinal “processes” of the vertebra affected by stenosis. Spinous processes are the protrusions of the individual vertebra visible along the back. The X-Stop device distracts two vertebral segments and relieves the pressure on the nerve roots caused by the stenosis, which in turn often relieves leg and back pain. The X-Stop, a recent advance in spinal stenosis surgery, is not an alternative to spinal fusion back surgery, a procedure that eliminates the natural flexion and rotation of the fused vertebrae. The X-Stop is ideal for patients with very mild spinal stenosis. For more advanced disease, the X-Stop is not applicable because the implant cannot be used when decompression surgery is necessary to remove the bony elements pressing on nerve roots. In such situations, where decompression surgery is performed in conjunction with spine stabilization, the TOPS System may be a more relevant solution for maintaining the spine’s native motion.
As developers of treatments for advanced spinal stenosis and associated conditions, we at Premia Spinerecommend that patients learn about all their treatment options. If you have a back condition that’s causing pain or is affecting your mobility, be certain to learn about all the choices available to you.
