Other complications included endplate injury (3.5%), cage malposition (2.7%), poor incision healing (1.9%), anterior longitudinal ligament injury (1.6%), vascular injury (1.6%), cage subsidence (1.2%), intestinal obstruction (1.2%), and peritoneal injury (0.4%). The complication rate was higher in the Multi-level fusion group than in the single-level group (21.9% vs. 15.5%, P=0.237). The incidences of neurological deficits (7.8% vs. 5.7%, P=0.538) and screw-related complications (7.8% vs. 4.6%, P=0.331) were also higher in the Multi-level group; however, none of these differences reached statistical significance.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The overall perioperative complication rate in this cohort was 17.1%, and the perioperative complications were manageable.
