Introduction: The cervicothoracic junction comprises C7 to T3 and has unique anatomical and biomechanical properties. multi-level subaxial cervical fixation usually continues to T1 or T2 in order to keep the cervicothoracic junction stable. However, this long segment fixation has disadvantages.Our study focus on degeneration of the C7-T1 level after long segment subaxial cervical fixation and fusion stopping at C7.
Methods: Included were patients with cervical degenerative disease who underwent posterior cervical fusion and fixation from 2009-2015. All complications were captured. Postoperative X-ray and CT confirmed fusion at six and twelve months after surgery. X-ray and CT confirmed screw loosening, misplacement, pull-out, breakage, or rod breakage.
Results: Of the 174 patients reviewed, 83 underwent cervical laminectomy and fixation that stopped at C7.C7-T1 sagittal Cobb angle was measures and no significant change was found between the preoperative and one-year postoperative follow-up. No spondylolisthesis was seen, and postoperative cervical MRI did not show signal changes at this level. The complication rate was low.
Conclusions: Posterior cervical spine fixation and fusion stopping at C7 can correct and maintain cervical sagittal parameters, and does not result in acceleration of C7-T1 degeneration.
Patient Care: Posterior cervical spine fixation and fusion stopping at C7 can correct and maintain cervical sagittal parameters, and does not result in acceleration of C7-T1 degeneration.
Learning Objectives: By the conclusion of this session, participants should be able to: Identify an effective treatment subaxial cervical fixation and fusion stopping at C7. .
