概括

皮肤上放置的珍珠串 (SOP) 和锁定压缩板 (LCP) 显示出明显更高的位移和较低的刚度,而不是外部固定器. 这些生物力学特性表明,SOP和LCP可能不适合大型狗的骨折修复.

科学领域:

骨科生物力学骨科生物力学
兽医外科植入物兽医外科植入物

背景情况:

外部固定器是骨折修复的标准,但正在探索替代植入物.
皮肤外板提供了一个不那么侵入性的选择,但它们的生物力学性能需要评估.

研究的目的:

为了比较皮肤上螺纹珠 (SOP) 和锁定压缩板 (LCP) 与 Ia 型外部固定器的生物力学.
评估SOP和LCP的适用性,作为狗骨折修复中外部固定器的替代品.

主要方法:

测试了3.5毫米SOP,3.5毫米LCP和Ia型外部固定器的结构.
进行了200N的非破坏性轴向压缩测试和100%位移的负载到故障测试.
计算了每个结构的中位数最大位移和中位数最大负载.

主要成果:

与SOP (8.5毫米) 和LCP (10.3毫米) 相比,外部固定器的最大位移 (1.2毫米) 显著降低.
外部固定器比SOP (244N) 和LCP (168N) 承受了明显更高的负载 (766N) 到100%的位移.
与外部固定器相比,SOP和LCP都显示了硬度和承载能力的统计学上显著差异.

结论:

类型Ia的外部固定器明显比皮肤上SOP和LCP更坚硬和更稳定.
皮肤上放置的锁定板表现出高位移和低度,可能使它们不适合在典型的轴承负载下在大型狗中进行临床骨折修复.
可能需要进一步的研究来探索修改或替代应用在兽医骨科科外皮板.

The Bone Matrix

The Bone Matrix

Bone contains a relatively small number of cells entrenched in a matrix of collagen fibers that provide an adherent surface for inorganic salt crystals. Both components of the matrix, organic and inorganic, contribute to the unusual properties of bone. Without collagen, bones would be brittle and shatter easily. Without mineral crystals, bones would flex and provide little support. This can be observed by an experiment: when the minerals of a bone are dissolved by soaking the bone in acid or...
