Abstract

The aim of this study was to compare the compressive forces generated by Dynamic Compression Angle-Stable Interlocking Nail (DCASIN) with those of traditional Dynamic Compression Plates (DCP) and Locking Compression Plates (LCP) using synthetic diaphyseal bone models (SDBM). Three groups were established based on the fixation method (G-DCASIN, G-DCP, and G-LCP), with implants fixed to SDBM simulating a transverse fracture, comprising 10 repetitions per group. A strain-gauge load cell was positioned in the SDBM gap to measure compressive forces in kilograms, recorded 30 s after the completion of each group-specific compression technique. For G-DCASIN, the proximal SDBM was compressed against the load cell using the external implantation guide and compression device. For G-DCP and G-LCP, the same-side double loading technique was applied to the proximal SDBM. Compressive forces among groups were compared using the Kruskal-Wallis test followed by Dunn's post-hoc analysis. The mean compressive forces recorded for G-DCASIN, G-DCP, and G-LCP were 22.56 ± 5.1 kg, 27.28 ± 1.86 kg, and 11.65 ± 1.69 kg, respectively. Both G-DCASIN and G-DCP exhibited significantly greater compressive forces compared to G-LCP (p = 0.0013 and p < 0.0001, respectively), whereas G-DCASIN and G-DCP did not differ significantly (p = 0.2228). In this mechanical trial, DCASIN demonstrated the ability to generate interfragmentary compression superior to LCP and comparable to DCP. The combination of compressive capability and angle-stable locking suggests that this model may be a viable option for the treatment of transverse fractures of long bones.

动压稳角联锁钉与传统动压板和锁紧压板产生的压缩力比较

本研究的目的是利用合成骨干骨模型（SDBM）比较动态压缩角稳定联锁钉（DCASIN）与传统动态压缩钢板（DCP）和锁定压缩钢板（LCP）产生的压缩力。采用G-DCASIN、G-DCP和G-LCP固定方法，将假体固定于模拟横向骨折的SDBM上，每组重复10次。在SDBM间隙中放置应变式测压元件，测量以公斤为单位的压缩力，记录每组特定压缩技术完成后30秒的压缩力。对于G-DCASIN，使用外部植入引导和压缩装置将近端SDBM压缩到称重传感器上。对于G-DCP和G-LCP，近端SDBM采用同侧双加载技术。使用Kruskal-Wallis测试比较各组之间的压缩力，然后进行Dunn的事后分析。G-DCASIN、G-DCP和G-LCP的平均压缩力分别为22.56±5.1 kg、27.28±1.86 kg和11.65±1.69 kg。与G-LCP相比，G-DCASIN和G-DCP表现出更大的压缩力（p = 0.0013和p <； 0.0001），而G-DCASIN和G-DCP没有显著差异（p = 0.2228）。在这项机械试验中，DCASIN证明了产生碎片间压缩的能力优于LCP，与DCP相当。压缩能力和角度稳定锁定的结合表明，该模型可能是治疗长骨横向骨折的可行选择。

期刊介绍： Research in Veterinary Science is an International multi-disciplinary journal publishing original articles, reviews and short communications of a high scientific and ethical standard in all aspects of veterinary and biomedical research. The primary aim of the journal is to inform veterinary and biomedical scientists of significant advances in veterinary and related research through prompt publication and dissemination. Secondly, the journal aims to provide a general multi-disciplinary forum for discussion and debate of news and issues concerning veterinary science. Thirdly, to promote the dissemination of knowledge to a broader range of professions, globally. High quality papers on all species of animals are considered, particularly those considered to be of high scientific importance and originality, and with interdisciplinary interest. The journal encourages papers providing results that have clear implications for understanding disease pathogenesis and for the development of control measures or treatments, as well as those dealing with a comparative biomedical approach, which represents a substantial improvement to animal and human health. Studies without a robust scientific hypothesis or that are preliminary, or of weak originality, as well as negative results, are not appropriate for the journal. Furthermore, observational approaches, case studies or field reports lacking an advancement in general knowledge do not fall within the scope of the journal.
