摘要

目的描述使用三维打印患者特异性引导系统治疗腊肠犬胫骨远端屈曲畸形的情况,并回顾性报告临床和影像学结果:使用三维打印的患者特制导引系统,对 7 只腊肠犬的 9 个肢体的胫骨远端曲折畸形进行矫正截骨治疗。计算机断层扫描数据经处理后获得胫骨的虚拟三维模型,该模型用于基于计算机辅助设计的手术规划、三维打印患者特制导引系统的设计以及胫骨矫正计划与效果的评估。临床结果通过跛行评分和术后至少 15 个月的主人报告问卷进行评估:结果:所有肢体的步态异常都得到了缓解。8根胫骨的截骨愈合顺利。一根胫骨的植入失败,但成功进行了修补。计划中的畸形矫正与已实现的畸形矫正之间存在良好的相关性,平均平移误差具有临床意义:三维打印的患者特异性截骨和还原引导系统有助于准确矫正胫骨脚外翻畸形,临床效果非常好。在所有病例中,使用正交锁定钢板稳定的开放式截骨术和无需植骨的开放式截骨术都能获得令人满意的骨愈合效果。

Surgical correction of pes varus deformity in dachshunds using three-dimensional-printed patient-specific guide system: nine tibiae in seven cases (2018-2022).

Objectives: To describe the use of a three-dimensional-printed patient-specific guide system for the treatment of distal tibial varus deformity in Dachshunds and retrospectively report the clinical and radiographic outcome.

Materials and methods: Pes varus deformity in nine limbs of seven dachshunds was treated with corrective osteotomy using a three-dimensional-printed patient-specific guide system. Data from computed tomography were processed to obtain virtual 3D-models of the tibias, which were used for computer-aided design-based surgical planning, three-dimensional-printed patient-specific guide system design and evaluation of planned versus achieved tibial correction. Clinical outcomes were evaluated by lameness score and post-operative owner-reported questionnaire at a minimum of 15 months.

Results: The gait abnormality resolved in all limbs. The osteotomy healed uneventfully in eight tibiae. Implant failure occurred in one tibia but was successfully revised. There was good correlation between planned and achieved deformity correction, with mean translational error <1 mm in all planes, and mean angulation correction error <2° in all planes.

Clinical significance: A 3D-printed patient-specific osteotomy and reduction guide system facilitates the accurate correction of tibial pes varus deformity with very good clinical outcomes. Opening osteotomy, stabilised with orthogonal locking plates and without the application of bone graft led to satisfactory bone healing in all cases.

期刊介绍: Journal of Small Animal Practice (JSAP) is a monthly peer-reviewed publication integrating clinical research papers and case reports from international sources, covering all aspects of medicine and surgery relating to dogs, cats and other small animals. These papers facilitate the dissemination and implementation of new ideas and techniques relating to clinical veterinary practice, with the ultimate aim of promoting best practice. JSAP publishes high quality original articles, as well as other scientific and educational information. New developments are placed in perspective, encompassing new concepts and peer commentary. The target audience is veterinarians primarily engaged in the practise of small animal medicine and surgery. In addition to original articles, JSAP will publish invited editorials (relating to a manuscript in the same issue or a topic of current interest), review articles, which provide in-depth discussion of important clinical issues, and other scientific and educational information from around the world. The final decision on publication of a manuscript rests with the Editorial Board and ultimately with the Editor. All papers, regardless of type, represent the opinion of the authors and not necessarily that of the Editor, the Association or the Publisher. The Journal of Small Animal Practice is published on behalf of the British Small Animal Veterinary Association and is also the official scientific journal of the World Small Animal Veterinary Association
