    • A dynamic rod implantable into a patient and connectable between two vertebral anchors in adjacent vertebral bodies is provided. The rod fixes the adjacent vertebral bodies dynamically providing immediate postoperative stability and support of the spine. The rod comprises a first rod portion having a first engaging portion connected to a second rod portion having a second engaging portion. The rod includes at least a one bias element configured to bias a deflection or translation of the first rod portion relative to the second rod portion. The first engaging portion includes at least one side or integral spring formed in the first engaging portion to bias a deflection of the second rod portion relative to the first rod portion. The rod permits relative movement of the first and second rod portions allowing the rod to carry some of the natural flexion and extension moments that the spine is subject to.
    • 提供了植入患者体内并可在相邻椎体内的两个椎骨锚固件之间连接的动态杆。 该杆固定相邻的椎体,动态地提供立即的术后稳定性和支撑脊柱。 杆包括第一杆部分,其具有连接到具有第二接合部分的第二杆部分的第一接合部分。 所述杆包括至少一个偏置元件,所述至少一个偏置元件构造成偏置所述第一杆部分相对于所述第二杆部分的偏转或平移。 第一接合部分包括形成在第一接合部分中的至少一个侧面或整体弹簧,以偏压第二杆部分相对于第一杆部分的偏转。 杆允许第一和第二杆部分的相对运动允许杆承载脊柱所受到的一些自然弯曲和延伸力矩。

    • A dynamic rod implantable into a patient and connectable between two vertebral anchors in adjacent vertebral bodies is provided. The dynamic rod fixes the adjacent vertebral bodies together in a dynamic fashion providing immediate postoperative stability and support of the spine. The dynamic rod comprises a first rod portion dynamically connected to a second rod portion at a retainer that has separate chambers for receiving rod portions. One rod portion is configured for longitudinal movement and the other rod portion is configured for polyaxial angulation relative to the retainer. The dynamic rod is configured such that the retainer is located proximate to one of the facet joints when implanted into a patient. The dynamic rod permits relative movement of the first and second rod portions allowing the rod to carry some of the natural flexion, extension and rotation moments of the spine.
    • 提供了一种可植入患者并可连接在相邻椎体内的两个椎骨锚之间的动态杆。 动态连杆以动态的方式将相邻椎体固定在一起,为脊柱提供即时的术后稳定性和支撑。 动态杆包括在保持器处动态连接至第二杆部分的第一杆部分,该保持器具有用于接收杆部分的分开的腔室。 一个杆部分构造成纵向移动,而另一个杆部分构造成相对于保持器成多轴角度。 动态杆被构造成使得保持器在植入患者体内时位于小关节之一附近。 动态杆允许第一杆部分和第二杆部分的相对运动,从而允许杆承载脊柱的一些自然弯曲,伸展和旋转力矩。

    • A dynamic rod implantable into a patient and connectable between two vertebral anchors in adjacent vertebral bodies is provided. The dynamic rod fixes the vertebral bodies together in a dynamic fashion providing immediate postoperative stability and support of the spine. The dynamic rod comprises a first rod portion and a second rod portion connected together. The dynamic rod further includes at least a one bias element configured to provide a bias force in response to deflection or translation of the first rod portion relative to the second rod portion. The dynamic rod includes a locking construct which advantageously enables the extension and/or angulation of one rod portion with respect to the other rod portion to be reversibly locked in position. The dynamic rod permits relative movement of the first and second rod portions allowing the rod to carry some of the natural flexion and extension moments of the spine.
