Patient pain intensity was evaluated by a 10-point visual analog scale (VAS), with a score (ranging from 0\u2009=\u2009no pain to 10\u2009=\u2009unbearable pain) that was collected before the procedure, at baseline; and at months 1, 6 and 12 after the interventional procedure. The assessment of quality of life (QOL) impairment was evaluated by the Oswestry Disability Index (ODI) questionnaire, which was administered beforehand at baseline; and at months 1, 6 and 12 after the interventional procedure. The vertebral canal area was measured by magnetic resonance imaging (MRI) scans before the treatment and at the one-year follow-up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>All patients completed the study with no complications. Both the Falena group and Aperius group of surgery patients showed a statistically significant reduction of their VAS and ODI scores at the 6- and 12-month follow-up ( p\u2009&lt;\u20090.0001). A statistically significant increase in the vertebral canal area was observed both in the group that received Falena ( p\u2009&lt;\u20090.0001) and in the group that received Aperius ( p\u2009=\u20090.0003). At the 1-year follow-up, we observed that there was a higher increase of vertebral canal area in those patients whom were treated with the Falena device ( p\u2009&lt;\u20090.001).<\/jats:p>\n
