摘要： A facet joint replacement implant may have a posterior stabilization surface designed to restrict posterior motion of a vertebra with respect to an adjacent, inferior vertebra. The facet joint replacement implant replaces the natural articular surface of one of the vertebrae, and articulates with a natural articular surface or with an articular surface of a second implant on the other vertebra. The posterior stabilization surface may be on a posterior flange of a superior facet joint implant, which extends posteriorly of a corresponding inferior facet joint implant. The inferior facet joint implant has an abutment surface that abuts the posterior stabilization surface as the superior vertebra begins to move posteriorly with respect to the inferior vertebra, thereby limiting the posterior motion.

摘要： Superior and/or inferior facets of one or more facet joints may be replaced by superior and/or inferior facet joint prostheses. In one embodiment, a kit of superior or inferior prostheses is provided, in which the prostheses have at least two dimensions that vary among members of the kit independently of each other. Each prosthesis may have a bone engaging surface having a surface that is polyaxially rotatable against a corresponding resection of a vertebra. Each prosthesis may also have an articulating surface shaped such that, after attachment to the spine, the replaced or partially replaced facet joints provide a larger medial-lateral range of motion when the spine is flexed than when the spine is extended. Crosslinks may be used to connect left and right prosthesis together in such a manner that they are stabilized in a position in which they are seated directly against the vertebra.

摘要： Superior and/or inferior facets of one or more facet joints may be replaced by superior and/or inferior facet joint prostheses. In one embodiment, a kit of superior or inferior prostheses is provided, in which the prostheses have at least two dimensions that vary among members of the kit independently of each other. Each prosthesis may have a bone engaging surface having a surface that is polyaxially rotatable against a corresponding resection of a vertebra. Each prosthesis may also have an articulating surface shaped such that, after attachment to the spine, the replaced or partially replaced facet joints provide a larger medial-lateral range of motion when the spine is flexed than when the spine is extended. Crosslinks may be used to connect left and right prosthesis together in such a manner that they are stabilized in a position in which they are seated directly against the vertebra.

摘要翻译： 一个或多个小关节的上和/或下小面可以由上和/或下小面关节假体代替。 在一个实施例中，提供了一种上或下假体的套件，其中所述假体具有至少两个尺寸，所述尺寸在所述套件的各个构件之间彼此独立地变化。 每个假体可以具有骨接合表面，其具有能够相对于脊椎的相应切除而被多轴旋转的表面。 每个假体还可以具有成形为使得在附接到脊柱之后，当脊柱弯曲时，被替换的或部分替换的小关节提供更大的内侧 - 内侧运动范围，而不是当脊柱延伸时。 交叉连接可以用于将左和右假体连接在一起，使得它们被稳定在它们直接抵靠椎骨的位置。
