Plates currently in use for the management of bone fracture made of metal present with various problems. We manufactured carbon fiber reinforced plastic (CFRP) plates from Pyrofil T/530 puriplegs overlaid at cross angles of +/- 10 degrees, +/- 20 degrees, and +/- 30 degrees for trial and carried out an experimental study on rabbit tibiofibular bones using 316L stainless steel plates of comparable shape and size as controls. The results indicate the influence of CFRP plate upon cortical bone was milder than that of stainless steel plate, with an adequate stabilizing force for the repair of fractured rabbit tibiofibular bones. CFRP has the advantages over metals of being virtually free from corrosion and fatigue, reasonably radiolucent and able to meet a wide range of mechanical requirements. This would make CFRP plate quite promising as a new devices of treating fracture of bones.
目前用于治疗骨折的金属板存在各种问题。我们用Pyrofil T/530原丝以±10度、±20度和±30度的交叉角铺设制造了碳纤维增强塑料（CFRP）板用于试验，并使用形状和尺寸相当的316L不锈钢板作为对照，对兔胫腓骨进行了实验研究。结果表明，CFRP板对皮质骨的影响比不锈钢板更轻微，对兔胫腓骨骨折修复具有足够的稳定力。CFRP比金属具有几乎无腐蚀和疲劳、适度的射线可透过性以及能够满足广泛机械要求等优点。这使得CFRP板作为一种治疗骨折的新装置很有前景。
