Evaluation of a patient-specific 3D-printed guide for ventral slot surgery in dogs: An ex vivo study.
Objective: To evaluate the accuracy of ventral slot creation in canine cadavers with a three-dimensional (3D)-printed drill guide compared to the freehand technique.
Methods: Computed tomography (CT) data was used to create patient-specific 3D-printed surgical guides for ventral slot creation. Intervertebral sites were randomized to undergo either a guided (n = 12) or freehand (n = 12) ventral slot by a novice surgery resident. Postoperative CT images were used to compare ventral slot dimensions, shape, and position.
Results: Free-hand ventral slots were significantly shorter than the intended dimensions (p < .01). Dimensions of the guide-assisted ventral slots were not statistically different from the planned dimensions (p = .88, p = .72). Use of the guides resulted in improved accuracy for ventral slot positioning relative to midline and slot shape (difference in coefficient of variations, 32%, and 40%, respectively).
Conclusion: Ventral slot dimensions were more accurate when created with the patient-specific 3D-printed guide compared to the freehand technique.
Clinical significance: Use of a 3D-printed patient specific surgical guide improves accuracy of ventral slot creation in canine cadavers and improves surgical precision when used by a single novice surgical resident. The results of this study support evaluation of the guides in small breed cadavers and live patients.
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.
