    • A spinal implant provides support for desired parts of the spine. The implant can provide support in fusion situations. The spinal implant includes a pair of longitudinal rods and a transverse rod. A pair of variable cross-link devices couple the transverse rod, respectively, to the first and second longitudinal rods. Each variable cross-link device includes a body, having a curved member, a plug, and a rod engaging member. Fastening the plug into the body of the respective variable cross-link device causes application of force that couples the plug and the rod engaging member to the respective longitudinal rod. Fastening the plug also causes application of force that couples the rod engaging member to the transverse rod. Furthermore, fastening the plug causes application of force that couples the respective longitudinal rod to couple to the variable cross-link device. The surgical procedure may use minimally invasive surgery or non-minimally invasive surgery, as desired.
    • 脊柱植入物为脊椎的所需部分提供支撑。 植入物可以在融合情况下提供支持。 脊柱植入物包括一对纵向杆和横向杆。 一对可变交联装置分别将横杆连接到第一和第二纵向杆。 每个可变交联装置包括具有弯曲构件,塞子和杆接合构件的主体。 将插头固定到相应的可变交联装置的主体中引起将插头和杆接合构件连接到相应纵向杆的力。 紧固塞子还引起将杆接合构件连接到横杆的力。 此外,紧固插头会导致连接相应的纵向杆以耦合到可变交联装置的力的施加。 根据需要,外科手术可以使用微创手术或非微创手术。

    • A spinal stabilization system may be formed in a patient. In some embodiments, a minimally invasive procedure may be used to form a spinal stabilization system in a patient. Bone fastener assemblies may be coupled to vertebrae. Each bone fastener assembly may include a bone fastener and a collar. The collar may be rotated and/or angulated relative to the bone fastener. Extenders may be coupled to the collar to allow for formation of the spinal stabilization system through a small skin incision. The extenders may allow for alignment of the collars to facilitate insertion of an elongated member in the collars. An elongated member may be positioned in the collars and a closure member may be used to secure the elongated member to the collars. A reducer may be used to achieve reduction of one or more vertebral bodies coupled to a spinal stabilization system.
    • 脊柱稳定系统可以形成在患者体内。 在一些实施例中,微创手术可用于在患者体内形成脊柱稳定系统。 骨头紧固件组件可以联接到椎骨。 每个骨紧固件组件可以包括骨紧固件和颈圈。 轴环可以相对于骨紧固件旋转和/或成角度。 延伸器可以联接到套环以允许通过小皮肤切口形成脊柱稳定系统。 延伸器可以允许套环的对准以便于细长构件在套环中的插入。 细长构件可以定位在套环中,并且闭合构件可用于将细长构件固定到套环。 可以使用减速器来实现联接到脊柱稳定系统的一个或多个椎体的减少。
