A head-to-head comparison between open and minimally invasive surgery (MIS) techniques for treatment of ASD has yet to be performed.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>OBJECTIVE:<\/jats:bold>\n                    To examine the impact of MIS approaches on construct length and clinical outcomes in comparison to traditional open approaches when treating similar ASD profiles.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>METHODS:<\/jats:bold>\n                    Two multicenter databases for ASD, 1 involving MIS procedures and the other open procedures, were propensity matched for clinical and radiographic parameters in this observational study.

Statistical significance was found for mean levels fused (4.8 for circumferential MIS [cMIS] and 10.1 for open), mean interbody fusion levels (3.6 cMIS and 2.4 open), blood loss (estimated blood loss 488 mL cMIS and 1762 mL open), and hospital length of stay (6.7 days cMIS and 9.7 days open). There was no significant difference in preoperative radiographic parameters or postoperative clinical outcomes (Owestry Disability Index and visual analog scale) between groups. There was a significant difference in postoperative lumbar lordosis (43.3\u00b0 cMIS and 49.8\u00b0 open) and pelvic incidence-lumbar lordosis correction (10.6\u00b0 cMIS and 5.2\u00b0 open) in the open group.
