The treatment of spinal disorders requires the consideration of a number of factors and understanding the type of material we are implanting is important. Alloys have different mechanical properties and behave differently under different physiologic conditions. Spinal implants need to have good performance in the characteristics of biofunctionality and biocompatibility. In this review, the alloys titanium, cobalt-chrome, nitinol, and tantalum will be examined closely. Several of the important properties that are considered when selecting an alloy for use in spinal instrumentation are explored and detailed for each. This allows for an assessment and comparison of each alloy and a possible determination of which is the best alloy for specific surgery or the best alloy for use in specific situations.
脊柱疾病的治疗需要考虑多个因素，了解我们所植入材料的类型很重要。合金具有不同的机械性能，在不同的生理条件下表现也不同。脊柱植入物需要在生物功能性和生物相容性方面具有良好的性能。在这篇综述中，将对钛合金、钴铬合金、镍钛诺合金和钽合金进行详细研究。探讨并详细阐述了在选择用于脊柱器械的合金时所考虑的几个重要特性。这有助于对每种合金进行评估和比较，并有可能确定哪种合金最适合特定的手术或特定情况下使用。
