Randomized Controlled Trial Multicenter Study
Interspinous process device versus standard conventional surgical decompression for lumbar spinal stenosis: randomized controlled trial.
To assess whether interspinous process device implantation is more effective in the short term than conventional surgical decompression for patients with intermittent neurogenic claudication due to lumbar spinal stenosis. ⋯ This double blinded study could not confirm the hypothesized short term advantage of interspinous process device over conventional "simple" decompression and even showed a fairly high reoperation rate after interspinous process device implantation.
