    Area of Science:

    • Minimally Invasive Spine Procedures
    • Interventional Pain Management

    Background:

    • Sciatica due to herniated intervertebral discs is a common cause of debilitating pain.
    • Standard conservative treatments and surgical interventions have limitations.
    • Chemonucleolysis offers a less invasive alternative.

    Purpose of the Study:

    • To evaluate the safety and efficacy of chemonucleolysis for treating sciatica.
    • To define patient selection criteria for optimal outcomes.
    • To position chemonucleolysis as an intermediate treatment option.

    Main Methods:

    • Chemonucleolysis involves the percutaneous injection of chymopapain into the affected intervertebral disc.
    • Patient selection excluded those with non-organic pain, spinal stenosis, or prior surgical failure.

  • Proper needle placement and adequate enzyme dosage were critical technique components.

    • Main Results:

    • The procedure is safe and can be performed under local anesthesia.
    • Good results can be anticipated when performed on carefully selected patients.
    • The technique requires precise needle placement and adequate chymopapain delivery.

    Conclusions:

    • Chemonucleolysis is a viable and safe procedure for specific sciatica cases.
    • It serves as an effective bridge between conservative management and traditional surgery.
    • Exclusion criteria are crucial for maximizing treatment success.
