Clinical outcomes of 20 brachycephalic dogs with thoracolumbar spinal deformities causing neurological signs treated with spinal stabilization using 3D-printed patient-specific drill guides.
Objective: To describe the clinical outcomes for pugs and French bulldogs with congenital vertebral malformations, undergoing thoracolumbar spinal stabilization surgery using 3D-printed patient-specific drill guides. To evaluate the accuracy of pedicle screw placement in this group of dogs.
Study design: Retrospective descriptive study.
Animals: Twenty dogs (12 pugs and eight French bulldogs).
Methods: Medical records searched between August 2018 and March 2021 for pugs and French bulldogs diagnosed with congenital vertebral abnormalities via magnetic resonance imaging (MRI) scan and computed tomography (CT) scan causing T3-L3 myelopathy signs that underwent spinal stabilization surgery using 3D-printed patient-specific drill guides followed by a postoperative CT scan. The short-term outcome was based on the neurological grade (modified Frankel score-MFS) on the day after surgery, day of discharge, and at the follow-up examination at 4 to 6 weeks after surgery. The mid-term outcome was obtained via an online questionnaire (or direct examination in one case).
Results: Twenty dogs met the inclusion criteria (19/20 grade 2 MFS, 1/20 grade 4 MFS). No complications were reported in the immediate postoperative period and optimal pedicle screw placement was obtained in 169/201 of screws. Twenty-four hours after surgery 16/20 dogs displayed an unchanged neurological grade. Short-term outcomes revealed a static (17/20) or improved (2/20) neurological grade. Ten owners participated in the online questionnaire. All patients were reported to be ambulatory; however, 7/10 dogs displayed abnormal gait. Neurological signs had remained static (6/10) or improved (3/10) in comparison with the dogs' preoperative status at a median of 883.5 days from the surgery.
Conclusion: Dogs in this study had a favorable short-term outcome and mid-term outcome evaluation revealed a static/improved neurological status.
Clinical significance: Thoracolumbar spinal stabilization surgery using 3D-printed patient-specific drill guides showed a favorable outcome in brachycephalic breeds affected by vertebral deformities.
期刊介绍：
Veterinary Surgery, the official publication of the American College of Veterinary Surgeons and European College of Veterinary Surgeons, is a source of up-to-date coverage of surgical and anesthetic management of animals, addressing significant problems in veterinary surgery with relevant case histories and observations.
It contains original, peer-reviewed articles that cover developments in veterinary surgery, and presents the most current review of the field, with timely articles on surgical techniques, diagnostic aims, care of infections, and advances in knowledge of metabolism as it affects the surgical patient. The journal places new developments in perspective, encompassing new concepts and peer commentary to help better understand and evaluate the surgical patient.
