The primary driver of the surgical versus medical management decision in canine IVDD is the severity of neurological signs, specifically ambulatory status and the presence or absence of deep pain perception.

For non-ambulatory dogs, surgery is the recommended treatment. The 2022 ACVIM consensus statement designates surgical decompression as the standard of care for non-ambulatory dogs with IVDD. Veterinary Reco… Surgical decompression has historically been associated with higher success rates, quicker recovery, and lower recurrence risk compared to medical management. Veterinary Reco… That said, conservative management remains a valid alternative when surgery is unavailable due to financial or geographic constraints — a large proportion of small, non-brachycephalic dogs with acute thoracolumbar disc extrusion do recover ambulation without surgery. Journal of Vete…

Deep pain perception status is the critical triage point within the non-ambulatory group. For deep pain-positive (DPP) non-ambulatory dogs, an estimated 86% recover ambulation with conservative management alone. Journal of Vete… For deep pain-negative (DPN) dogs — the most severely affected — surgical outcomes range from 25% to 76% success, compared to close to 100% for less severely affected dogs. Journal of Vete… Conservative management can still yield functional recovery in some DPN dogs, including those with severe spinal cord compression on MRI, though the exact clinical and imaging predictors of which DPN dogs will recover without surgery remain incompletely defined. Journal of Vete…

For cervical IVDD specifically, the threshold for surgery differs from thoracolumbar disease. Medical management — analgesics, anti-inflammatory drugs, muscle relaxants, and strict exercise restriction — is the first-line approach for dogs with a first episode of neck pain and no or minor neurological deficits. Journal of the… Surgery is recommended for dogs with recurrent cervical pain or those presenting with neurological deficits. Journal of the… Medical management of cervical IVDD carries a success rate of 48.9%, with 33% of dogs experiencing recurrence after initial improvement and 18.1% failing conservative management entirely. Journal of the…

Recurrence risk is a secondary factor that can tip the decision toward surgery. For thoracolumbar disc extrusion, recurrence rates after surgical treatment range from 0% to 42%. Journal of Vete… Prophylactic fenestration of 6 intervertebral discs at the time of decompressive surgery reduces recurrence from 17% to 7%. Journal of Vete… For cervical disc extrusion treated surgically, recurrence rates of 2% to 64% have been reported. Veterinary Surg… Radiographically visible disc calcification is a significant predictor of herniation in Dachshunds and a risk factor for recurrent herniation after surgery, making fenestration of calcified adjacent discs advisable at the time of decompressive surgery. Journal of Vete…

If clinical signs fail to respond to medical management, surgical treatment should be pursued regardless of initial presentation severity. Veterinary Reco…
