Abstract

Background: Changes in the sagittal balance after Anterior Cervical Discectomy with Fusion (ACDF) are phenomena that have not yet been sufficiently studied. The aim of this study is to assess these changes. Methods: Twenty-eight patients who underwent ACDF for cervical spondylosis were examined. The study was divided into three stages: Preoperative, and early and late postoperative. Sagittal alignments were analyzed based on X-ray AP and lateral images: Angles C1-C7, C2-C7, C1-C2, C1- C4, C4-C7 and cervical Sagittal Vertical Axis (cSVA). Results: The cervical lordosis C2-C7 decreased by 13% in early monitoring, after which it increased by 60% in the late postoperative phase. Post-hoc analysis showed that the measured values between early and late postoperative monitoring differ significantly. cSVA increased by 23% in early control and then decreased by 18% in the late postoperative phase. Post-hoc analysis showed that the measured values significantly differ between preoperative and early postoperative monitoring and between early and late postoperative monitoring. Conclusion: It has been shown that the long-term effect of ACDF is the correction of the sagittal balance of the cervical spine. Immediately after the procedure, a disturbance in the cervical spine curvature to the morphology of the entire spine is observed.
