In the last two decades interspinous devices have gained a wide popularity in lumbar spine surgery. The Wallis implant, made of PEEK (polyetheretherketone) and Dacron bands, was one of the first spacers to be largely used in patients affected by lumbar spinal stenosis, particularly in non-English speaking countries. Subsequently the DIAM spacer gave a new impulse to this kind of surgery, due to its properties of posterior dynamic stabilization. Basing upon strong research and clinical evidences, the X-STOP device has been recognized as having a role in the surgical treatment of lumbar spinal stenosis causing Neurogenic Intermittent Claudication (NIC), particularly if compared with non-operative therapy and decompressive surgery. The Coflex U-shaped titanium implant has been used in same clinical scenarios and in its latest version it is used as an adjunct to interbody fusion.
