    • An intervertebral disk prosthesis in a preferred embodiment has a matrix of bioincorporable fabric, and a nuclear core centrally mixed into the matrix. The core is formed by impregnating the fabric substrate centrally with a polymer, preferably of liquid form that cures into a viscoelastic solid, in which each component—polymer and fabric—reinforces the other against tearing, shearing and weakening under stress. The core is a hybrid composite adapted for elastic deformation centrally of the matrix, in which the polymer is mixed with the fabric, and is surrounded by the outer bioincorporable fabric margin of the matrix. In another embodiment, the nuclear core is separated from an outer sheath of the bioincorporable fabric by an intermediate ligament encasement that surrounds the purely polymeric core In either embodiment, each edge of the outer fabric that interfaces a vertebral end plate is impregnated with an agent to stimulate osseus incorporation and anchoring. An adjunct anchoring system with penetration of bone of adjacent vertebra may be used to for attachment until and after bioincorporation occurs.
    • 在优选实施例中的椎间盘假体具有生物可组合织物的基质和中心地混合到基质中的核心。 芯是通过将聚合物中心浸渍在织物基材上而形成的,聚合物优选固化成粘弹性固体的液体形式,其中每种组分 - 聚合物和织物 - 加强另一种,以防止在应力下的撕裂,剪切和弱化。 芯是一种混合复合材料,适用于基体中心的弹性变形,其中聚合物与织物混合,并被基体的外部生物可组合织物边缘包围。 在另一个实施方案中,核芯通过围绕纯聚合物芯的中间韧带包裹与生物可合并织物的外护套分开。在任一实施方案中,与织物端板相接的外部织物的每个边缘都浸渍有药剂 刺激骨结合和锚固。 可以在生物公司发生之前和之后使用具有相邻椎骨的穿透的附属锚固系统进行附着。
