【摘要】：正髖、膝關(guān)節(jié)置換重建中應(yīng)用傳統(tǒng)的多孔材料涂層關(guān)節(jié)假體已取得了較好的臨床效果。這些多孔移植材料在關(guān)節(jié)重建術(shù)中被用來(lái)實(shí)現(xiàn)非骨水泥的生物固定。如鈷鉻合金和鈦等離子涂層的應(yīng)用代表著大多數(shù)常規(guī)應(yīng)用多孔涂層材料來(lái)實(shí)現(xiàn)骨長(zhǎng)入。盡管這些常規(guī)多孔涂層材料已經(jīng)顯示具有較好的臨床效果,但是它們具有一些與生俱來(lái)的弊端,例如與骨相關(guān)的低孔隙率(30%~50%)、低摩擦特性和和較高的彈性模量。多孔鉭,一種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.
