Summary

This study validated an objective rating system for selecting patients for chemonucleolysis. The system accurately predicted treatment success and future surgical outcomes for lumbar disc herniation.

Area of Science:

  • Neurosurgery
  • Orthopedic Surgery
  • Pain Management

Background:

  • Patient selection is crucial for successful lumbar disc herniation treatments.
  • An objective rating system previously aided selection for laminectomy and discectomy.

Purpose of the Study:

  • To evaluate a revised objective rating system for patient selection in chemonucleolysis.
  • To assess the system's predictive value for chemonucleolysis and subsequent surgical outcomes.

Main Methods:

  • A revised 100-point objective rating system was applied to 101 patients undergoing chemonucleolysis.
  • The system assessed neurologic signs, root tension, imaging (myelogram/CT), and psychosocial factors.
  • Patients were evaluated at least one year post-injection.

Main Results:

  • The objective rating score predicted the outcome of chemonucleolysis.
  • The score demonstrated stronger prediction for ultimate surgical outcomes, including cases requiring laminectomy post-chemonucleolysis failure.

Conclusions:

  • The revised objective rating system is a valuable tool for patient selection in chemonucleolysis.
  • The system effectively predicts both initial treatment success and long-term surgical results for lumbar disc herniation.
