STUDY DESIGN: Retrospective analysis of consecutive case series.
OBJECTIVE: To introduce a novel method of stabilizing the cranium using bivector traction in posterior cervical fusions.
METHODS: A retrospective review of 50 consecutive patients undergoing instrumented posterior cervical arthrodesis was performed. All patients had at least 3 levels of subaxial fusion using the bivector traction apparatus. Patients' 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.
RESULTS: 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 -6.0° and -10°, respectively ( = .04). The mean pre-and postoperative cSVA was 30.5 mm and 32 mm, respectively ( = .6). There were no complications related to placement of the Gardner-Well tongs.
CONCLUSION: The bivector traction is an easy, safe, and effective method of stabilizing the head and obtaining adequate cervical sagittal alignment.
