An intervertebral implant is formed by using porous hydroxyapatite as the frame model and filling metal powder therein, followed by subjecting to a sintering/molding process to thereby constituting an intervertebral implant with partially degradable hydroxyapatite/metal bulk, wherein the hydroxyapatite structure will be gradually degraded with the time elapsed since the human body implantation for guiding bone tissues to attach into the porous metal, thereby forming a stable fusion effect for upper and lower bones.一種椎間植入物,特別係指一種利用多孔氫氧基磷灰石為支架模型填入金屬粉體後經燒結成形,組成局部可降解之氫氧基磷灰石/金屬塊材之椎間植入物,隨植入人體時間氫氧基磷灰石結構逐步進行降解,並引導骨組織攀附於多孔金屬內部,形成穩固上部與下部骨頭融合效果。
