Abstract

Objective: The aim of the study was to determine if a novel arthrodesis technique for the equine metacarpophalangeal (MCP) joint using a human non-contact bridging (NCB), polyaxial locking compression plate system has biomechanical and potential clinical advantages versus a traditional 5.5 mm stainless steel locking compression plate (LCP) under biomechanical testing.

Study design: An ex vivo biomechanical equine cadaver study.

Sample population: A total of 11 MCP joints collected from adult Thoroughbred horses euthanized unrelated to musculoskeletal disease.

Methods: Each pair of MCP joints were randomly implanted with either an A LCP or NCB plate. Each construct was tested in cyclic loading followed by single cycle to failure in axial compression. Displacement at a target load of 1 kN over 3600 cycles at 1 Hz was recorded prior to single cycle to failure testing.

Results: In cyclic testing, overall displacement recorded in constructs with the NCB plates was less than that of the LCP constructs with a mean (least square mean - LSM) difference of 0.33 mm (p = .03). There was no difference between groups in single cycle testing for yield point (p = .55) and maximum load at failure (p = .95).

Conclusion: While a significant difference was found between constructs during cyclic testing, LCP versus NCB constructs conferred no difference in stability in single cycle to failure testing.

Clinical significance: The increased stability of the NCB plate in cyclic loading, comparable failure strength to the LCP and versatility of polyaxial screws support further investigation for possible clinical use of the NCB plate for equine fetlock arthrodesis.

马掌指关节融合术中单轴与多轴锁定加压钢板的离体比较。

目的：本研究的目的是在生物力学测试中确定使用人非接触桥接（NCB）、多轴锁定加压钢板系统进行马掌指关节（MCP）的新型关节固定术与传统的5.5 mm不锈钢锁定加压钢板（LCP）相比是否具有生物力学和潜在的临床优势。研究设计：一项离体马尸体生物力学研究。样本群体：从与肌肉骨骼疾病无关的成年纯种马安乐死中收集的总共11个MCP关节。方法：每对MCP关节随机植入A LCP或NCB钢板。每个结构都在循环加载中进行测试，然后进行单周期测试，直到轴压破坏。在单周期失效测试之前，记录了目标载荷为1kn、3600次、1hz的位移。结果：在循环测试中，NCB钢板构建体记录的总位移小于LCP构建体，平均（最小二乘平均- LSM）差为0.33 mm （p = .03）。在单周期试验中，屈服点（p = 0.55）和失效时最大负荷（p = 0.95）组间无差异。结论：在循环测试中，LCP与NCB结构之间存在显著差异，但在单周期到失败测试中，LCP与NCB结构的稳定性没有差异。临床意义：NCB钢板在循环载荷下的稳定性增加，与LCP相当的破坏强度和多轴螺钉的多功能性支持进一步研究NCB钢板在马股骨关节融合术中的临床应用。

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.
