Lumbar interspinous devices: indications, surgical aspects, clinical considerations

Abstract

Interspinous devices (or spacers) are currently used in lumbar spine surgery, but their use is still controversial, mainly due to confusion between so-called first and second-generation spacers, and unrespect of formal indications to implant. Our first aim is trying to offer an interpretation for a correct indication of surgical implantation, paying additional attention to those pathological conditions in which these devices must not be used; second, to identify the right clinico-surgical method to avoid potential errors in this surgery; third, to stress those surgical tricks directed to perform a successful implant of these spacers.
