In \u201copen\u201d spine surgery, intraoperative tools can fine tune alignment; minimally invasive spine surgery techniques may not allow for this type of intraoperative adjustment. The aim of this study was to identify pre-operative radiographic parameters that accurately predict post-operative alignment after minimally invasive lumbar spine surgery. We hypothesized that pre-operative supine and extension sagittal alignment would predict post-operative standing alignment.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>50 consecutive patients underwent lateral or anterior lumbar interbody fusion with or without percutaneous posterior instrumentation by a single-surgeon. Sagittal alignment parameters were evaluated on pre-operative standing scoliosis radiographs, dynamic radiographs, supine CT scout, and 6-week post-operative standing radiographs. Demographic and perioperative data were analyzed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The mean age was 67.8\u00a0years. The mean BMI was 29.7. On average, 3 levels were instrumented (range, 2\u20136). Surgical time was 4.5 \u00b1 1.8\u00a0hours. Following surgery, global lordosis increased from 44.7 \u00b1 17\u00b0 to 48.6 \u00b1 16\u00b0 ( P = .001). However, there was no significant difference between the pre-operative supine (48.5 \u00b1 15\u00b0), pre-operative extension (49.2 \u00b1 18\u00b0), or 6-week post-operative standing radiographs (48.6 \u00b1 16\u00b0). There were strong correlations between post-operative alignment and pre-operative supine (r = .825) and extension (r = .851) alignment.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Our results suggest that pre-operative supine and extension radiographs could be a gold standard for minimally invasive lumbar spine surgery alignment correction as they predict post-operative alignment.
