X-STOP
X-STOP is a lumbar spinous process distraction device that is used to treat lumbar spinal stenosis. The device is an “indirect” decompression device that relies on distraction between the lumbar vertebra in order to open the spinal canal and hence decompress the spinal nerves. In one well designed study, the device has been compared against and been shown to be more effective than conservative care (therapy, medications, and epidural steroid injections). However, X-STOP has not been directly compared with microdecompression surgery. In addition, X-STOP is indicated in patients with mild to moderate stenosis symptoms whereas microdecompression surgery is better for patients with severe symptoms).
