SAN FRANCISCO--(BUSINESS WIRE)--July 5, 2006--A four-year follow-up study published in the July issue of Journal of Spinal Disorders & Techniques, a prestigious scientific journal, supports previous results that show patients suffering from lumbar spinal stenosis have significantly greater improvement with a new, minimally invasive procedure, the X STOP® Interspinous Process Decompression (IPD®) System (“X STOP”) and remained stable over time. These results come on the heels of a recently published study in the Journal of Neurosurgery: Spine that demonstrated the X STOP to have significantly greater clinical success (63.4%) than non-operative care which was found to have a clinical success rate of only 12.9 percent.
