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• (Note: X-STOP® was withdrawn from the market)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.
