Plain-English summary
A group of dogs with severe back pain due to a slipped disc underwent surgery to relieve pressure on their spinal cord. Some dogs had a traditional hemilaminectomy, while others had a less invasive mini-hemilaminectomy. The results showed that the mini-hemilaminectomy was more effective, reducing spinal cord compression by about 62% compared to 34% for the traditional surgery. This suggests that the mini-hemilaminectomy may be a better option for treating this condition in dogs, as it is less invasive and provides better access for the surgeon.

Abstract
The aim of this study was to compare the reduction of spinal cord compression after surgical treatment of dogs with acute thoracolumbar intervertebral disc (IVD) extrusion achieved using hemilaminectomy versus mini-hemilaminectomy techniques. This was a prospective randomized study with client-owned dogs presented with acute IVD extrusion that were allocated to surgical treatment using hemilaminectomy ( = 15) or mini-hemilaminectomy ( = 15) techniques. Plain and intravenous-contrast computed tomography was performed pre- and postoperatively. The preoperative minimal cross-sectional dimension of the spinal cord (MDSC) and the postoperative minimal cross-sectional dimension of the spinal cord (MDSC) were measured at the level of greatest compression. The minimal diameter of the uncompressed spinal cord was measured in a similar way both pre- (MDUSC) and postoperatively (MDUSC). Dogs in the mini-hemilaminectomy group had significantly greater reduction of compression (RC) ( < 0.01) after surgery compared to dogs in the hemilaminectomy group. The mean RC in the hemilaminectomy group was 34.6% and in the mini-hemilaminectomy group 62.6%. Our results showed a significantly greater reduction of spinal cord compression for mini-hemilaminectomy compared to hemilaminectomy. Additionally, mini-hemilaminectomy could be a preferred method due to its minimal invasiveness and easier access to lateral fenestration.
