Clinical Trial Summary

To determine if the effectiveness of the X-STOP® implant is equivalent (non-inferior) to that of conventional laminectomy in patients with lumbar spinal stenosis as measured by the Zurich Claudication Questionnaire.


Clinical Trial Description

The clinical study described herein aims to compare surgical outcomes of X-STOP® Interspinous Process Decompression® (IPD) system implantation and conventional laminectomy in subjects requiring surgical intervention due to symptoms of lumbar spinal stenosis (LSS) and a confirmed diagnosis on MRI, X-ray or CT. Patients with LSS meeting entry criteria will be randomized to either X-STOP® IPD or laminectomy treatment. Patients will remain blinded to the procedure received. The primary study outcome is group differences in the Zurich Claudication Questionnaire (ZCQ) at 12 months post-operative. In addition, each subject will undergo follow-up assessment at 2 weeks and 2, 12 and 24 months post-operative. The secondary objective is to compare safety profiles and the radiographic outcomes between groups using pre- and post-operative MRI and flexion/extension X-rays, to measure changes in canal and neuroforaminal cross sectional areas and spinal stability, respectively. ;
