Magnetic resonance (MR) imaging reveals diverse findings in the cervical spine after anterior diskectomy and fusion (ADF). Common postoperative issues include bony canal stenosis and disc herniations, with graft signals evolving over time.

Area of Science:

  • Neurosurgery
  • Radiology
  • Spinal Surgery

Background:

  • Anterior diskectomy and fusion (ADF) is a common procedure for cervical spine pathologies.
  • Postoperative magnetic resonance (MR) imaging is crucial for evaluating surgical outcomes and complications.

Purpose of the Study:

  • To characterize the spectrum of MR imaging findings in the cervical spine following anterior diskectomy and fusion (ADF).
  • To correlate MR findings with operative reports in postoperative cervical spine patients.

Main Methods:

  • Retrospective review of MR imaging in 73 patients who underwent cervical spine surgery.
  • Correlation of MR findings with initial operative reports.

Main Results:

  • Early MR findings (within 1 month) show bone grafts as distinct signal alterations.

  • Graft and vertebral body signal changes persist up to 2 years post-ADF.
  • Common findings include bony canal stenosis (19/73) and disc herniations (21/73) above or below fusion levels.
  • Hypertrophic bone was visualized as anterior extradural defects with variable signal intensity.

    • Conclusions:

    • MR imaging demonstrates characteristic changes in bone grafts and fusion sites over time.
    • Bony canal stenosis and disc herniations are frequent complications after ADF.
    • Understanding these MR findings is essential for accurate postoperative assessment.
