Abstract

Objective: To describe the clinical and diagnostic imaging findings of pet pigs with osteoarthritis and determine the efficacy of intra-articular (IA) injections in managing lameness.

Study design: Retrospective observational study.

Animals: A total of 16 pet pigs diagnosed with osteoarthritis and treated with non-steroidal medications and IA injections.

Methods: Cases, diagnostic imaging, and clinical data were collected from the medical records of Purdue University. The owners were interviewed by telephone to collect follow-up data regarding the degree of lameness following joint treatment.

Results: A total of 13 of 16 pigs presented for lameness evaluation. A diagnosis of osteoarthritis was determined with computed tomography (CT) (n = 10) or digital radiography (n = 7). In all, 24 joints were treated with triamcinolone. Following injection, 13 of 16 (81%) pigs showed improvement in lameness, as measured by decreases in lameness scores assigned by the owner (p = .0183). The duration of the effect ranged from a few weeks to several months. Those with no or minimal improvement tended to have advanced osteoarthritis in joints other than those treated. There were no complications reported. The use of CT for injection guidance did not show a significant difference in outcomes over the use of radiographic guidance.

Conclusion: With an accurate diagnosis, IA injections seemed to be a beneficial therapy for pet pigs.

Clinical relevance: The use of IA corticosteroids to treat lameness due to osteoarthritis in pigs represents an effective therapy that reduces lameness.

影像引导下关节内注射猪骨关节炎的诊断成像结果和处理。

目的：描述骨性关节炎宠物猪的临床和诊断影像学表现，并确定关节内注射（IA）治疗跛行的疗效。研究设计：回顾性观察性研究。动物：共有16只被诊断为骨关节炎的宠物猪，并接受了非甾体药物和IA注射治疗。方法：收集普渡大学的病例、诊断影像和临床资料。通过电话采访这些主人，收集有关关节治疗后跛行程度的后续数据。结果：16头猪中有13头进行了跛行评估。通过计算机断层扫描（CT）（n = 10）或数字x线摄影（n = 7）确定骨关节炎的诊断。共有24个关节接受曲安奈德治疗。注射后，16头猪中有13头（81%）的跛行有所改善，这是通过饲主给出的跛行评分降低来衡量的（p = 0.0183）。效果的持续时间从几周到几个月不等。与接受治疗的患者相比，那些没有或只有轻微改善的患者往往患有晚期关节骨关节炎。无并发症报道。使用CT进行注射引导与使用x线引导的结果没有显着差异。结论：在诊断准确的情况下，注射IA对宠物猪似乎是一种有益的治疗方法。临床相关性：使用IA皮质类固醇治疗猪骨关节炎引起的跛行是一种有效的治疗方法，可以减少跛行。

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.
