All patients had at least 3 levels of subaxial fusion using the bivector traction apparatus. Patients\u2019 demographic data was recorded for the following: pre- and postoperative cervical lordosis, pre- and postoperative cervical sagittal vertical alignment (cSVA), and intraoperative complications from pin placements.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n A total of 50 patients were studied. There were 31 females and 19 males. The mean age at the time of surgery was 49 years (range 35-79). A mean 5.8 levels were fused. The most common levels fused were C2-T3 in 14 patients followed by C2-T2 in 7 patients. In no case did the surgeon or assistant have to scrub out to adjust the alignment. The mean pre- and postoperative cervical lordosis was \u22126.0\u00b0 and \u221210\u00b0, respectively ( P = .04). The mean pre-and postoperative cSVA was 30.5 mm and 32 mm, respectively ( P = .6).
