Abstract

Objective: To describe a distraction-stabilization technique using a three dimensional (3D)-printed titanium cervical integrated spacer (CIS) in a horse with a C6-C7 severe discospondylitis.

Animal: A 4-year-old 540 kg Sächsisch-Thüringisches Schweres Warmblut gelding.

Study design: Single case report.

Methods: A 4-year-old Schweres Warmblut gelding with a 14-month history of gait abnormalities, progressing to grade 3/5 ataxia on the Mayhew scale, was diagnosed via radiography and computed tomography with severe discospondylitis and significant spinal cord compression at C6-C7. A surgical arthrodesis was elected. Under radiographic control, a CIS was placed using a 3D-printed instrument set.

Results: At 16 months, radiographs, confirmed implant stability, maintained vertebral alignment and successful fusion. Gait evaluation showed no overt ataxia and only mild thoracic limb dysmetria.

Conclusion: 3D-printed CIS appears a promising implant for stabilizing equine caudal vertebrae (C6-C7).

3d打印钛颈椎集成垫片用于椎间盘脊柱炎马C6-C7融合。

目的：描述一种使用三维（3D）打印的钛颈椎集成垫片（CIS）对患有C6-C7严重椎间盘脊柱炎的马进行分散-稳定技术。动物：一头4岁的540公斤Sächsisch-Thüringisches Schweres Warmblut骟马。研究设计：单例报告。方法：一匹4岁的Schweres Warmblut马，步态异常14个月，在Mayhew量表上进展为3/5级失调，通过x线摄影和计算机断层扫描诊断为严重的脊椎炎和C6-C7处明显的脊髓压迫。选择手术关节融合术。在射线照相控制下，使用3d打印的仪器组放置CIS。结果：在16个月时，x线片证实了种植体的稳定性，保持了椎体对齐并成功融合。步态评估显示没有明显的共济失调，只有轻微的胸肢运动障碍。结论：3d打印CIS是稳定马尾椎（C6-C7）的一种很有前途的植入物。

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.
