    • In one embodiment, a spinal fixation assembly includes an elongated member, such as a spinal rod, configured for placement adjacent the spine and a bone engaging fastener, such as a bone screw having a lower portion configured for engaging a vertebra and a head that is at least partially spherical. The assembly further includes a receiver member defining a bore therethrough from a top end to a bottom end, a recess for receiving the head of the bone screwing fastener therein, and a lower opening at said bottom end of the receiver member through which the bone screw extends. The recess is configured to at permit pivoting of the bone screw within the receiver member until the head is fixed within the recess. The receiver member also includes a channel communicating with the bore and having an upper opening at the top end of the receiver member for insertion of the spinal rod into the channel. In one embodiment, two compression members are provided, each being formed of a temperature responsive material and having a first configuration at a first temperature and a different second configuration at a different second temperature in which the compression member contracts about a portion of the receiver member to thereby compress the receiver member about both the head of the bone screw within the recess and the spinal rod within the channel.

    • A transverse fixator assembly for spanning between a number of longitudinal members situated adjacent a patient's vertebrae and methods for fixation of the spine which allow variation of the distance between two or more vertebrae. The assembly includes a number of connectors configured to span the distance between and engage the longitudinal members. The connectors define a thru-hole for engaging a bone bolt which is engaged to a vertebra plus a number of spikes projecting from the connector. A locking mechanism is configured to prevent the bolt from rotating relative to the connector when the nut is being tightened. One or more of the connectors may be a dynamic connector which is slidably engaged to the longitudinal members to vary the distance between the vertebrae for compression or distraction.
    • 用于跨越位于患者脊椎附近的多个纵向构件之间的横向固定器组件和用于固定脊柱的方法,其允许两个或更多个椎骨之间的距离的变化。 该组件包括多个连接器,其被构造成跨越纵向构件之间的距离并且与纵向构件接合。 连接器限定用于接合骨螺栓的通孔,所述骨螺栓与椎骨加上从连接器突出的多个尖峰接合。 锁定机构构造成当螺母被拧紧时防止螺栓相对于连接器旋转。 一个或多个连接器可以是动态连接器,其可滑动地接合到纵向构件以改变椎骨之间的距离用于压缩或分心。

    • A multi-axial bone screw assembly includes a bone screw having a partially spherical head. The bone screw head is truncated at an upper surface in which a tool receiving recess is defined. The assembly includes a receiver member including a central bore that defines a tapered recess to receive a contracting collet carrying the head of the bone screw. The bore of the receiver member also defines a channel communicating with the recess and configured to receive a spinal rod therein. A portion of the channel is threaded to receive a set screw above the rod. The assembly also includes a contracting collet disposed between the rod and the head of the bone screw. The collet defines a partially spherical recess to receive the head of the bone screw, and includes deflectable fingers that substantially surround the screw head. As the set screw is tightened into the receiver member, the set screw compresses the rod against the collet, which presses the collet into the tapered recess of the receiver member, thereby deflecting the fingers of the collet against the bone screw head.
    • 多轴骨螺钉组件包括具有部分球形头部的骨螺钉。 骨螺钉头在限定工具容纳凹部的上表面处被截断。 该组件包括一个接收器构件,该接收器构件包括中心孔,该中心孔限定锥形凹槽,以容纳承载骨螺钉头部的收缩夹头。 接收器构件的孔还限定了与凹部连通且被构造成在其中容纳脊柱杆的通道。 通道的一部分被螺纹接纳在杆上方的固定螺钉。 组件还包括设置在杆和骨螺钉头部之间的收缩夹头。 夹头限定了部分球形的凹部以接收骨螺钉的头部,并且包括基本上围绕螺钉头的可偏转的指状物。 当定位螺钉被紧固到接收器构件中时,定位螺钉将杆压靠在夹头上,该夹头将夹头压入接收器构件的锥形凹槽中,从而使夹头的指状物偏转抵靠骨螺钉头。
