Dimethicone effectively prevents secondary nerve root adhesion after lumbar intervertebral disk removal in dogs. Gelatin sponge, however, exacerbated adhesion by inducing scar tissue formation.

Area of Science:

  • Veterinary Surgery
  • Neurosurgery
  • Biomaterials Science

Context:

  • Lumbar intervertebral disk disease is a common condition requiring surgical intervention.
  • Secondary nerve root adhesion is a significant complication following spinal surgery.
  • Effective prevention strategies are crucial for improving surgical outcomes.

Purpose:

  • To evaluate the efficacy of dimethicone in preventing secondary nerve root adhesion post-discectomy in a canine model.
  • To compare the effects of dimethicone and gelatin sponge on nerve root adhesion.

Summary:

  • Twenty-seven dogs underwent lumbar intervertebral disk removal and were divided into three groups: dimethicone treatment (Group A), gelatin sponge application (Group B), and control (Group C).
  • Post-operative assessments included macroscopic observation, nerve root motility measurement, and histological examination at 2, 4, and 12 weeks.

  • Results indicated dimethicone significantly reduced nerve root adhesion, while gelatin sponge promoted scar tissue formation and aggravated adhesion.

    • Impact:

    • Dimethicone shows promise as a therapeutic agent for preventing post-surgical nerve root adhesion.
    • Findings suggest that gelatin sponge may be contraindicated for preventing nerve root adhesion due to its pro-fibrotic effects.
    • This study provides valuable preclinical data for potential clinical applications in spinal surgery.
