IVDD: Navigating the Spectrum from Conservative Care to Surgery

Dr. Rosemary Stolzer, DVMCaninePre-RACE approval · credit hours set at approval

Intervertebral disc disease (IVDD) presents one of the most challenging decisions in veterinary neurology: when is conservative management appropriate, and when does the patient need surgery? This course breaks down the Hansen Type I vs. Type II distinction, the critical neurological grading scale (Grades 1–5), and the deep pain perception test that serves as the surgical decision inflection point. Learn the evidence-based multimodal pain protocol for conservative patients — NSAIDs, gabapentin, methocarbamol, acupuncture, and strict cage rest. Explore rehabilitation modalities including laser therapy, underwater treadmill, and e-stim that accelerate spinal cord recovery. Apply practical home nursing care strategies for the paraplegic or paretic patient. Follow Pretzel's case from acute Grade 3 paraparesis through 8 weeks of conservative management to full recovery.

Learning Objectives

  • 1Explain the pathophysiological differences between Hansen Type I and Type II IVDD, the zones of spinal cord injury, and the neurological grading scale (Grades 1–5) used to classify disease severity
  • 2Analyze the decision framework for conservative versus surgical management based on neurological grade, progression speed, deep pain perception, and owner factors including cost and time availability
  • 3Apply a multimodal pain management protocol for the conservatively managed IVDD patient, including NSAIDs, gabapentin, methocarbamol, acupuncture, and strict cage rest protocols
  • 4Evaluate the evidence for rehabilitation modalities — photobiomodulation (Class IV laser), underwater treadmill, neuromuscular electrical stimulation, and sling walking — in spinal cord injury recovery and recovery timelines
  • 5Apply practical home nursing care and quality-of-life strategies for the paraplegic or paretic IVDD patient, including bladder management, pressure sore prevention, exercise protocols, and wheeled cart fitting
