Overview

Retrospective cohort study compares long-term surgery outcomes in single-level cervical degeneration, indicating CDA is preferable.

Key Points

  • To compare long-term outcomes, including 10-year complication rates and necessary surgeries, between CDA and ACDF.
  • Retrospective cohort study of patients undergoing single-level CDA and ACDF from 2010 to 2022.
  • Patients were propensity-score matched 1:1 by age, sex, and Charlson Comorbidity Index.
  • Kaplan-Meier analysis used for determining cumulative incidence of secondary cervical procedures.
  • Cumulative incidence of secondary procedures was lower for CDA (8.7%) compared to ACDF (11.4%).
  • ACDF patients had higher reoperation likelihood (HR: 1.12, P=0.005).
  • Significantly higher risks observed for ACDF in spinal complications (HR: 4.73), nerve root compression (HR: 2.61), drainage (HR: 2.01), and mechanical failure (HR: 1.36), all P<0.05.
