    • An intervertebral disc nucleus replacement implant for positioning between adjacent vertebrae of a spinal segment comprises opposing superior and inferior end portions substantially aligned along a longitudinal axis and a compressible, elastic body surrounding part of the end portions. Each of the end portions includes a convex outer surface for contacting respective endplates of the adjacent vertebrae. Additionally, the elastic body includes an outer surface, with the implant having an outer periphery comprising the outer surfaces of the end portions and the outer surface of the body. In certain embodiments, the elastic modulus of the body is lower than the elastic modulus of each of the end portions and the body extends outward of the end portions transverse to the longitudinal axis, such that the body is configured to limit the amount of subsidence of the implant relative to the adjacent vertebrae.
    • 用于在脊椎节段的相邻椎骨之间定位的椎间盘髓核替代植入物包括沿着纵向轴线基本对准的相对的上下端部分和围绕端部的一部分的可压缩的弹性体。 每个端部包括用于接触相邻椎骨的相应端板的凸形外表面。 此外,弹性体包括外表面,其中植入物具有包括端部的外表面和主体的外表面的外周。 在某些实施例中,主体的弹性模量低于每个端部的弹性模量,并且主体从横向于纵向轴线的端部向外延伸,使得主体被构造成限制了主体的下沉量 植入物相对于相邻的椎骨。
