title: Interspinous process device versus standard conventional surgical decompression for lumbar spinal stenosis: randomised controlled trial.
abstract: OBJECTIVE
  Is interspinous process device implantation more effective in the short term (eight weeks) than conventional surgical decompression for patients with intermittent neurogenic claudication due to lumbar spinal stenosis?
  
  
  CONCLUSIONS
  The use of interspinous implants did not result in a better outcome than conventional decompression, but the reoperation rate was significantly higher.
  
  
  BACKGROUND
  Bony decompression and treatment with interspinous process devices are superior to conservative and non-surgical treatment for intermittent neurogenic claudication due to lumbar spinal stenosis. Interspinous implants surgery is not superior to bony decompression, and the reoperation rate is significantly higher.
