Abstract

The corrosion of stainless-steel screws used to fix carbon-fibre reinforced plastic (CFRP) plates to human fractures was compared with the corrosion on similar screws used to fix stainless-steel AO plates. Corrosive changes were noted in both sets of screws with similar frequency and severity; however, the stainless-steel plates were 'in situ' almost twice as long as the CFRP ones, showing that the corrosive changes occurred more rapidly on screws in contact with CFRP. Nevertheless, over the implantation time necessary for bone healing, corrosion was very mild and there is no clinical contra-indication to the use of stainless-steel and CFRP together in this particular application.

摘要

将用于将碳纤维增强塑料(CFRP)板固定到人体骨折部位的不锈钢螺钉的腐蚀情况,与用于固定不锈钢AO板的类似螺钉的腐蚀情况进行了比较。两组螺钉都出现了频率和严重程度相似的腐蚀变化;然而,不锈钢板在“原位”的时间几乎是CFRP板的两倍,这表明与CFRP接触的螺钉腐蚀变化发生得更快。尽管如此,在骨愈合所需的植入时间内,腐蚀非常轻微,在这一特定应用中,将不锈钢和CFRP一起使用没有临床禁忌。
