Abstract
Interspinous Posterior Devices (IPDs) are spinal implantable devices used to treat lumbar degenerative diseases, with lumbar stenosis as the main indication. They are defined as devices for dynamic stabilization, because their aim is to perform a decompression of the spinal canal in case of stenosis, while preserving biomechanical properties of the spinal metamere. Lumbar stenosis is considered as the last phase of the degenerative cascade, the process of degeneration of spinal motor unit described by Kirkaldy-Willis, which identified as primary cause the hypermobility of the vertebras.

Interspinous Posterior Devices (IPDs) are spinal implantable devices used to treat lumbar degenerative diseases, with lumbar stenosis as the main indication
In the light of debatable results reported by the scientific community about the effectiveness of the IPDs, and the high rate of complications and re-operation showed, the North American Spine Society NASS performs and publishes in 2013 a revision of “evidence based clinical guideline for the diagnosis and treatment of degenerative lumbar spinal stenosis” that were previously drawn up from the NASS in 2006
This revision provides a clinical analysis and an extensive literature review about the different treatments available for lumbar stenosis, giving each a degree of recommendation from A to I: A is the degree of absolute recommendation, the gold standard, while I means the total lack of recommendation
