摘要： A double-jointed bone bolt for use in an apparatus for maintaining vertebra in a desired relationship. The apparatus has a rod that extends substantially along the spine and one or more bone bolts. At least one of the bone bolts is double jointed. The double-jointed bolt has a mounting portion with a hook or coarse threads to engage a vertebra, and the mounting portion is attached to a pivot post in a manner that allows the pivot post to be rotatable about a common axis in respect to the mounting portion. The pivot post of the bone bolt is then pivotally attached to a connector portion of the bone bolt that has machine threads upon which a surgeon may attach a clamp. The clamp has a second bolt and an arm. The second bolt holds the rod and the arm to the clamp. The second bolt has a first channel to attach to the rod, while the arm has a second channel to attach the double-jointed bone bolt.
摘要翻译：一种用于在所需关系中维持椎骨的装置中的双关节骨螺栓。该装置具有基本上沿着脊柱和一个或多个骨螺栓延伸的杆。至少有一个骨螺栓是双重接合的。双接头螺栓具有带钩或粗螺纹以与椎骨接合的安装部分，并且安装部分以允许枢轴柱相对于安装件绕公共轴线旋转的方式附接到枢轴柱一部分。骨螺栓的枢轴柱然后枢转地附接到具有机器螺纹的骨螺栓的连接器部分上，外科医生可以在其上附接夹具。夹具具有第二螺栓和臂。第二个螺栓将杆和臂固定在夹具上。第二螺栓具有附接到杆的第一通道，而臂具有用于附接双接头骨螺栓的第二通道。

摘要： Embodiments of a spinal implant system include a fixation element, a connector body, and a compression member. The fixation element has a bone engaging portion, a pivoting portion, and a hinge portion. The hinge portion permits pivotal motion of the pivoting portion relative to the bone engaging portion. Additionally, the connector body defines a channel configured for receipt of an elongate member and defines an elongate slot configured for receipt of the pivoting portion of the fixation element. The pivoting portion is positionable in any one of a plurality of positions along the elongate slot. The compression member is adapted to engage the pivoting portion of the fixation element and press against the connector body to lock the pivoting portion at a desired angular position relative to the bone engaging portion and lock the connector body to the fixation element at the desired position along the elongate slot.
摘要翻译：脊柱植入系统的实施例包括固定元件，连接器主体和压缩构件。固定元件具有骨接合部分，枢转部分和铰链部分。铰链部分允许枢转部分相对于骨骼接合部分枢转运动。另外，连接器主体限定通道，该通道被构造成用于接收细长构件并且限定被配置为接收固定元件的枢转部分的细长狭槽。枢转部分可定位在沿着细长槽的多个位置中的任何一个位置。压缩构件适于接合固定元件的枢转部分并且压靠连接器主体以将枢转部分相对于骨接合部分锁定在期望的角度位置，并且将连接器本体锁定在固定元件处于期望的位置细长槽。
