Chemonucleolysis can lead to persistent herniated disc images on CT scans, along with increased disc degeneration and facet joint issues. However, these findings did not negatively impact patient outcomes two years post-procedure.

Area of Science:

  • Radiology
  • Orthopedic Surgery
  • Spinal Intervention

Background:

  • Chemonucleolysis is a minimally invasive treatment for herniated discs.
  • Long-term CT imaging findings after chemonucleolysis require further characterization.

Purpose of the Study:

  • To evaluate CT findings at 6 months and 2 years post-chemonucleolysis.
  • To correlate imaging findings with clinical outcomes.

Main Methods:

  • Retrospective analysis of CT scans from 50 patients at 6 months and 34 patients at 2 years post-chemonucleolysis.
  • Assessment of disc herniation persistence, intradiscal degenerative signs, and facet joint degeneration.

Main Results:

  • Herniated disc images persisted in nearly 70% of cases at 2 years.

  • Increased intradiscal degenerative signs and facet joint degeneration were observed.
  • Despite imaging changes, clinical outcomes remained favorable at 2 years.

    • Conclusions:

    • Persistent herniated disc imaging after chemonucleolysis is common.
    • Degenerative changes on CT do not necessarily predict poor clinical outcomes.
    • Chemonucleolysis can provide good long-term results despite evolving imaging findings.
