Radiological parameters were evaluated preoperatively and at 5\u00a0years and compared between LIV-L3 and LIV-L4 groups, with subgroup analyses for high (\u22655\u00b0) vs low (&lt;5\u00b0) sacral slanting within each group.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Preoperative radiographs showed no significant differences between groups, except for the Cobb angle. In the LIV-L3 group, patients with sacral slanting \u22655\u00b0 presented greater DWA at 5\u00a0years, whereas those with slanting &lt;5\u00b0 demonstrated a gradual decrease in DWA. In the LIV-L4 group, patients with sacral slanting \u22655\u00b0 showed a progressive increase in C7-cervical sagittal vertical line, which was significantly greater at 5\u00a0years. Scoliosis Research Society-22 scores were similar between high and low slanting groups at the 5-year follow-up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>In patients with AIS and structural lumbar curve, increased preoperative sacral slanting was associated with an increased DWA below LIV when selecting LIV-L3.
