title: [Percutaneous interspinous distraction for the treatment of dynamic lumbar spinal stenosis and low back pain].
abstract: SURGICAL GOAL: Surgical treatment of dynamic lumbar spinal stenosis and discogenic/arthrogenic low back pain with a new percutaneous interspinous spacer as a therapeutic alternative to more invasive standard procedures.
  
  
  METHODS
  Central, lateral and foraminal dynamic lumbar spinal stenosis. Discogenic and arthrogenic (facet osteoarthritis) low back pain. Symptomatic, segmental hyperlordosis. Disc degeneration with dynamic (reducible) retrolisthesis. Interspinous pain ('Kissing-Spines').
  
  
  METHODS
  Osteoporosis. Conus-/Cauda-syndrome. Structural spinal stenosis. Spondylolisthesis (degenerative and/or isthmic). Deformities. Previous posterior operation in index segment.
  
  
  METHODS
  Percutaneous, minimally invasive implantation of an interspinous spacer (InSpace ™, Synthes, Oberdorf, Switzerland).
  
  
  METHODS
  Early unrestricted mobilization.
  
  
  RESULTS
  Good early results (after 2 year follow-up) in 42 patients with 76% subjective patient satisfaction rate. No approach related complications. Avoidance of the more invasive alternative procedure (decompression, fusion, total disc replacement) in 76.2% of the patients.
