    The study compares the Zero-P VA device with the plate-cage construct (PCC) for single-level anterior cervical discectomy and fusion (ACDF).

  • 2

    Both devices showed significant improvement in VAS and JOA scores postoperatively, indicating effective clinical outcomes for patients.

  • 3

    The Zero-P VA group experienced a significant decrease in segmental angle and anterior height compared to the PCC group at 3 and 12 months.

  • 4

    Segmental kyphosis was significantly higher in the Zero-P VA group at the 12-month follow-up, with a rate of 12% compared to 0% in the PCC group.

  • 5

    The Zero-P VA device offers comparable short-term clinical outcomes but inferior radiological stability compared to the PCC in ACDF procedures.
