【摘要】:正髋、膝关节置换重建中应用传统的多孔材料涂层关节假体已取得了较好的临床效果。这些多孔移植材料在关节重建术中被用来实现非骨水泥的生物固定。如钴铬合金和钛等离子涂层的应用代表着大多数常规应用多孔涂层材料来实现骨长入。尽管这些常规多孔涂层材料已经显示具有较好的临床效果,但是它们具有一些与生俱来的弊端,例如与骨相关的低孔隙率(30%~50%)、低摩擦特性和和较高的弹性模量。多孔钽,一种新型的生物材料的出
[Abstract]:The traditional porous material coated joint prosthesis has achieved good clinical effect in the reconstruction of hip and knee joint. These porous graft materials are used to achieve non-bone cement bioremediation in joint reconstruction. Applications such as cobalt-chromium alloy and titanium plasma coating represent most conventional application of porous coating materials to achieve bone growth. Although these conventional porous coating materials have shown good clinical effects, they have some inherent drawbacks, such as low porosity associated with bone (3050%), low friction properties and high elastic modulus.
