Researchers in the United Kingdom (UK) conducted a randomized controlled trial in 47 patients with lumbar spinal stenosis to compare treatment outcomes and costs of two competing surgical procedures: insertion of the X-Stop (Medtronic) interspinous distractor device and open decompression surgery with laminectomy. Both procedures improved the patients’ quality of life; however, overall, laminectomy gave patients a better quality of life and was also more cost-effective.
