    Abstract: A polyaxial orthopedic device for use with rod implant apparatus includes a screw having a curvate head, a cross bar mounting element having a socket into which the head of the screw is initially polyaxially nested. The cross bar mounting element further includes a vertical split which permits the socket to be expanded or compressed via the application of a corresponding force directed at the split. The cross bar mounting element further includes a pair of upwardly extending members which define a trough into which a cross bar element is positioned. The cross bar element includes features which permit the secure fixation of a rod thereto, as well as a selectively slideable element, such as a nut, which may be tightened to apply the compressive force necessary to compress the interior volume onto the head of the screw, thus locking the assembly in place.

    Abstract translation: 用于杆植入装置的多轴矫形装置包括具有弯曲头的螺钉，具有插座的横杆安装元件，螺钉的头部最初被多轴嵌套在该插座中。 横杆安装元件还包括垂直分割，其允许通过施加指向分割的相应力而使套筒膨胀或压缩。 横杆安装元件还包括一对向上延伸的构件，其限定横杆元件所定位的槽。 横杆元件包括允许杆固定到其上的特征，以及可选择性地可滑动的元件，例如螺母，其可以被紧固以施加压缩内部体积到螺钉头部所需的压缩力 ，从而将组件锁定就位。

    Abstract: An instrument for holding an intervertebral spacer includes a shaft having a proximal end forming a handle, and a distal end forming a claw subassembly for holding the spacer; the claw subassembly including a first pincer which is fixed at the distal end of the shaft and a second pincer which is selectively rotateable into and out of spacer holding association with said first pincer to hold and release, respectively, the spacer. The instrument includes an actuation mechanism for selectively rotating the second pincer, wherein the first and second pincers have opposing inner curved surfaces that extend to a distal end of the instrument.
