    • A posterior vertebral stabilizer (70, 270) has a resilient member (120, 274) such as a linear spring, which operates in tension and compression. The resilient member may be kept straight by a stabilization rod (74) extending through the spring, or by a telescoping assembly (272) that encases the resilient member (274). The ends (92, 94) of the stabilizer (70, 270) are attachable to pedicles of adjacent vertebrae so that the stabilizer (70, 270) adds stiffness to control flexion and extension of the vertebrae. Two such stabilizers (70, 270) may be used, and may be connected together by a crosslink (180) designed to limit relative rotation of the stabilizers (70, 270). Thus, the stabilizers (70, 270) may restrict axial rotation and lateral bending between the vertebrae, while permitting stiffened flexion and extension. Such stabilizers (70, 270) help provide the stiffness of a healthy intervertebral disc. In the event that fusion of the joint becomes necessary, a set screw (160, 340) or other component may be used to further restrict flexion and extension.
    • 后椎骨稳定器(70,270)具有弹性构件(120,274),例如线性弹簧,其在张力和压缩中起作用。 弹性构件可以通过延伸穿过弹簧的稳定杆(74)或包围弹性构件(274)的伸缩组件(272)保持直线。 稳定器(70,270)的端部(92,94)可附接到相邻椎骨的椎弓根,使得稳定器(70,270)增加刚度以控制椎骨的屈曲和伸展。 可以使用两个这样的稳定​​器(70,270),并且可以通过设计成限制稳定器(70,270)的相对旋转的交联(180)连接在一起。 因此,稳定器(70,270)可以限制椎骨之间的轴向旋转和侧向弯曲,同时允许加强的弯曲和伸展。 这种稳定器(70,270)有助于提供健康的椎间盘的刚度。 在需要接头融合的情况下,可以使用固定螺钉(160,340)或其它部件来进一步限制屈曲和伸展。

    • The intervertebral stabilization device (12, 170) preferably includes a planar spring (20, 180) enclosed within a housing (22, 172). The housing (122, 172) is joined to an articulation component (24, 25, 174, 175) at either end, and the articulation components (24, 25, 174, 175) have couplings (28, 178) connectable to anchoring components (19) which are securable to adjacent vertebrae. The planar spring (20, 180) can flex and retract providing relative motion between the adjacent vertebrae. The articulation components (24, 25, 174, 175) are ball and socket joints which allow the entire assembly to flexibly follow the curvature of the spine. A fusion rod (162) with articulation components and couplings (164) at either end may be substituted for the spring device. The couplings enable interchangeability between a fusion rod (162) assembly and spring assembly (12, 170).
    • 椎间稳定装置(12,170)优选地包括封闭在壳体(22,172)内的平面弹簧(20,180)。 壳体(122,172)在任一端连接到铰接部件(24,25,174,175),并且所述关节运动部件(24,25,174,175)具有可连接到锚定部件的联接件(28,178) (19),其可保证相邻的椎骨。 平面弹簧(20,180)可以弯曲和缩回以提供相邻椎骨之间的相对运动。 铰接部件(24,25,174,175)是球窝接头,允许整个组件灵活地跟随脊柱的曲率。 在任一端具有铰接部件和联接件(164)的熔化杆(162)可以代替弹簧装置。 联接器使得熔接杆(162)组件和弹簧组件(12,170)之间可互换。
