Description
Sakaguchi and colleagues look at what happens years after spinal surgery in small dogs with slipped discs, a common problem in breeds like Dachshunds. Hemilaminectomy, removing part of a vertebra to relieve the squeezed spinal cord, is the standard fix for type I thoracolumbar disc herniation. Their 2026 study gathered nineteen dogs that later suffered a recurrence. It compared scans at the original surgery site between first episode and relapse to see whether the healed site itself had caused the new trouble.
The operated disc had clearly thinned over time, with its height index significantly reduced at recurrence, and the maximal cord compression at that site was actually milder the second time around. Two dogs had regrown bone where the vertebra was opened, yet in no case did regrowth or the old site explain the new symptoms, which traced to fresh herniation instead.
