Focal intervertebral disc protrusion

Last edited: 4/15/2026

Overview

Focal intervertebral disc protrusion involves the displacement of disc material beyond the intervertebral space, leading to spinal cord compression and potential neurological deficits. 12

Diagnosis

  • Clinical signs include radiculopathy, motor deficits, and pain localized to the affected spinal region.
  • Imaging studies (e.g., MRI, CT myelography) are essential for confirming the diagnosis and assessing the extent of spinal cord compression.
  • Grading systems (e.g., Frankel grading) may be used to evaluate the severity of neurological impairment. 2
  • Management

  • First-line treatments:
  • - Minimally invasive microsurgical decompression: Effective for precise spinal cord decompression in severe cases, particularly in veterinary contexts 1. - Ozone therapy: Used alone or in combination with targeted drug injections for pain relief and functional improvement 2.
  • Adjunctive treatments:
  • - Targeted injection of corticosteroids (e.g., betamethasone): Combined with ozone therapy shows improved short-term efficacy and functional outcomes 2. - Postoperative analgesia: Limited opioid use post-surgery to minimize complications 1.

    Special Populations

  • Veterinary context: Minimally invasive techniques show promise in large breed dogs with disc protrusions 1.
  • Human populations: Specific considerations for pregnancy, pediatrics, and elderly patients are not addressed in the provided abstracts 2.
  • Key Recommendations

  • Consider minimally invasive microsurgical decompression for precise spinal cord decompression in severe focal intervertebral disc protrusions, particularly in veterinary cases (Evidence: Weak) 1.
  • Combine ozone therapy with targeted corticosteroid injections for enhanced short-term efficacy and functional recovery in lumbar disc protrusions (Evidence: Moderate) 2.
  • Limit postoperative opioid use to reduce complications and facilitate quicker recovery (Evidence: Weak) 1.
