A 'titanium interspinous process device (IPD)' is a minimally invasive spinal implant placed between the spinous processes of lumbar vertebrae. It is typically used to treat lumbar spinal stenosis, particularly in patients whose symptoms improve with spinal flexion.

A titanium interspinous process device is an implant made of titanium alloy, designed to act as a spacer between spinous processes, limiting spinal extension and decompressing neural elements.

  • Limits lumbar extension.
  • Maintains or increases the interspinous distance.
  • Enlarges the neural foramina and central canal.
  • Reduces load on the facet joints and posterior annulus.
  • Lumbar spinal stenosis with neurogenic intermittent claudication.
  • Symptom relief in flexion.
  • Mild to moderate cases without significant instability.
  • Severe spinal instability or spondylolisthesis > Grade I.
  • Osteoporosis or poor bone quality.
  • Active local or systemic infection.
  • Known allergy to titanium (rare).
  • Coflex® (Paradigm Spine)
  • Superion® (Vertiflex)
  • DIAM™ (Medtronic)
  • (Note: X-STOP® was withdrawn from the market)
  • Minimally invasive approach.
  • Preserves segmental motion.
  • Shorter recovery times.
  • Possible use under local anesthesia.
  • Fracture of the spinous process.
  • Device migration or loosening.
  • Infection.
  • Persistent or recurrent symptoms.
