Original Title: Efectividad y seguridad de los dispositivos interespinosos

Authors' objectives: The specific objectives are to assess the effectiveness, –in terms of quality of life, pain, functional capacity, disability, claudication, radiographic changes–, and safety –in terms of complications, adverse events, need for additional treatment– of the interspinous decompression devices for the treatment of patients with lumbar canal stenosis.

Authors' results and conclusions: -The included studies had a moderate quality of evidence with an average probability of bias and also heterogeneity in populations (different baseline characteristics, small sample size), interventions (different devices), comparators (absence sometimes reference pattern surgical) and outcomes (different questionnaires). As a result, extrapolation of these findings should be viewed with caution. -The systematic review identified data on the efficacy and safety of XSTOP, COFLEX and SUPERION devices, though, the majority of studies focused on the X-STOP device. -Studies with older publication date (until 2010) showed that interspinous decompression devices are likely to be used for the treatment of symptomatic lumbar spinal stenosis in patients who do not respond to conservative treatment. The identified studies confirmed the efficacy and safety of the device in the medium term (2 years) comparing against conservative treatment. Studies with longterm monitoring or studies comparing interspinous decompression devices against decompressive laminectomy (surgical treatment) were not localized. -Studies with more recent publication date (2013), comparing IDD versus surgical decompression laminectomy or fusion, showed that both interventions had similar efficacy, and that the IDD showed a higher number of reoperations with laminectomy even though they had fewer postoperative complications.
