All underwent a PSO of the lumbar spine to treat major sagittal imbalance. The amount of vertebral angular correction needed was calculated using the full balance integrated (FBI) method. A special plier, which allows to safely control the angular correction, was used intraoperatively. Preoperative and early postoperative global sagittal balance parameters were compared.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS<\/jats:title>\n                    <jats:p>\n                      The mean preoperative calculated correction angle (FBI) was 33.8\u00b0; the mean postoperative correction obtained was 32.1\u00b0. Lumbar lordosis was statistically greater than preoperatively (55.8\u00b0 vs 19.4\u00b0,\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      \u00a0&lt;\u00a0.0001). The global sagittal balance was improved, as shown by the increase of the spino-sacral angle from 122\u00b0 preoperatively to 128\u00b0 postoperatively (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      \u00a0=\u00a0.0547). None of the patients had an intraoperative or early postoperative neurologic complication. There were no mechanical intraoperative complications during correction nor at the first postoperative follow-up.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSION<\/jats:title>\n                    <jats:p>The advantages of the instrument are safe, precise, and efficient reduction, by a rotation of the pedicle screws close to the osteotomy line, thus avoiding collapse and lack of correction, complications usually seen with the conventional technique. Further prospective studies are needed to confirm these results.<\/jats:p>\n
