Abstract
Background and aim: Bilateral sacroiliac joint luxation, a condition primarily observed in cats, can significantly impact their quality of life. This study aimed to compare a control with three distinct fixation methods to identify the most robust fixation method capable of withstanding significant tensile stress.
Materials and methods: Twenty pelvic bone models of cats were made using a 3D printer with polylactic acid plastic. Each model was assembled by cutting the sacroiliac joints and pelvic girdle symphysis with a handsaw, then bonded with cyanoacrylate glue. 3D feline pelvic bone models were categorized into four significant groups, each consisting of five models. The study discovered that the three groups used distinct fixation methods: Two lag screws (DS), K-wires at the ilium wing and sacroiliac joints (TK), and K-wires at the sacroiliac joints (DK). The final group, not fixed, was the control.
Results: The results were characterized further through a mechanical compression force test using a universal testing machine. The most robust method at the sacroiliac joints, the DK technique, sustained a maximum force of up to 183.86 N while maintaining the correct bone alignment. The fixation method is more accessible and faster to implement in comparison to the DS method.
Conclusions: The DK group exhibited the greatest maximum load capacity among all groups. Sacroiliac joint luxation treatment can effectively be addressed using the K-wires fixation method. However, the DK need space of sacral body same as DS for fixation. Further clinical study should be performed.
背景和目的:双侧骶髂关节松弛主要发生在猫身上,会严重影响它们的生活质量。本研究旨在比较对照组和三种不同的固定方法,以确定能够承受巨大拉伸应力的最坚固的固定方法:使用聚乳酸塑料 3D 打印机制作了 20 个猫骨盆骨模型。每个模型都是用手锯切割骶髂关节和骨盆骨骺,然后用氰基丙烯酸酯胶水粘合而成。三维猫骨盆骨模型被分为四个重要组别,每个组别由五个模型组成。研究发现,三组使用了不同的固定方法:两根滞后螺钉(DS)、髂骨翼和骶髂关节处的 K 线(TK)以及骶髂关节处的 K 线(DK)。最后一组是未固定的对照组:通过使用万能试验机进行机械压缩力测试,进一步确定了结果的特征。骶髂关节处最坚固的方法是 DK 技术,它能承受最大 183.86 牛顿的力,同时保持正确的骨骼排列。与 DS 方法相比,这种固定方法更方便、更快捷:结论:在所有组别中,DK组的最大承重能力最强。结论:在所有组别中,DK组的最大承重能力最强,使用K线固定法可以有效治疗骶髂关节松弛。然而,DK组与DS组一样需要骶骨体的空间进行固定。应进行进一步的临床研究。
