Objective To assess the short‐term, mid‐term, and long‐term results after an individualized mini‐hemilaminectomy‐corpectomy (iMHC) procedure for treatment of acute and chronic thoracolumbar intervertebral disc disease in non‐chondrodystrophic dogs. Study Design Prospective study. Animals Client‐owned non‐chondrodystrophic large breed dogs (n = 57). Methods The iMHC procedure, combining mini‐hemilaminectomy (MH) and partial lateral corpectomy, was performed on non‐chondrodystrophic dogs with thoracolumbar disc disease. Neurological status was evaluated before surgery, for short‐term outcome on days 1 and 7 after surgery, for mid‐term outcome at 6 months after surgery, and for long‐term outcome at the conclusion of the study. Prognostic factors were statistically evaluated. P < .05 was considered significant. Results iMHC was performed on 57 dogs, with minimal intraoperative and postoperative complications. Short‐term neurological improvement was observed in 85.7% of dogs. Median hospitalization time after surgery was 2 days (range 0‐14) and was significantly shorter for dogs with a chronic history of clinical signs (1 day, range 0‐5) compared to acute onset (3 days, range 0‐14) and for those that were ambulatory at initial presentation (1 day, range 0‐5) compared to those that were not (3 days, range 0‐14). Long‐term evaluation included 53 surgeries with a mean follow‐up time of 29.4 months. Outcome was excellent in 19 dogs and good in 29 dogs (90.6% success rate). Excellent mid‐term and long‐term results were significantly more common in the dogs with only 1 affected disc space. Conclusion The iMHC procedure resulted in a short hospitalization time, minimal postoperative deterioration, and a high success rate.
