Lumbar Facet FiXation


Degenerative lumbar spinal stenosis

  • Complementary fixation to decompression
  • Spondylolisthesis ≤ Grade I, Scoliosis < 25°
FFX scan Canal lombaire


  • Post thermocoagulation failure
  • Mini-open approach

Complementary graft

  • Supplement to a pedicle fixation
  • Additional bony fusion of facet joints
