Surgical treatment of the spinal stenosis with an interspinous distraction device: do we really restore the foraminal height?

Abstract

Using the Coflex device is a minimal invasive, effective and safe procedure. Restoration of the foraminal height may not be a responsible factor for clinical improvement. We think microsurgical decompression looks responsible of the good clinical outcome and using interspinous device is unnecessary. Comparative clinical studies can be informative.
