    摘要： The present invention provides tools and methods designed to aid in the placement of artificial facet joints at virtually all spinal levels. One aspect of the present invention is a measurement tool for installing an artificial cephalad facet joint, the tool including a trial marker having a portion configured to be placed in a hole; and a trial body comprising a bore therethrough for slidaby receiving a portion of the trial marker. In some embodiments, the trial body further comprises an arm extending generally radially outward from the bore and configured to contact an opposing spinal prosthesis component. The trial body may further comprise a lower portion configured to be placed in the hole. The trial marker and the trial body are configured to cooperate to indicate a relative positioning between them. This measurement tool assists in the selection and/or configuration of an artificial cephalad facet joint for implantation in a patient. Another aspect is a method of using a spinal prosthesis component selection tool comprising accessing a target anatomy, creating a hole within a portion of the target anatomy, inserting a marker rod of a component selection tool in the hole, slidably adjusting a trial stem body along the marker rod until the trial body contacts an opposing spinal prosthesis component, determining the relative position between the trial body and marker rod, and selecting a component for implantation into the target anatomy based on the determined relative position.

    摘要翻译： 本发明提供了设计用于帮助在几乎所有脊柱水平放置人造小关节的工具和方法。 本发明的一个方面是一种用于安装人造头部小关节的测量工具，该工具包括具有被配置为放置在孔中的部分的试验标记; 以及试验体，其包括穿过其中的孔，用于滑动接收所述试验标记的一部分。 在一些实施例中，试验体还包括从孔径向向外延伸并构造成接触相对的脊椎假体部件的臂。 试验体还可以包括构造成放置在孔中的下部。 试验标记和试验体被配置为配合以指示它们之间的相对定位。 该测量工具有助于用于植入患者的人造头颅关节的选择和/或构造。 另一方面是一种使用脊椎假体部件选择工具的方法，包括进入目标解剖结构，在目标解剖结构的一部分内产生孔，将部件选择工具的标记杆插入孔中，沿着 所述标记杆直到所述试验体接触相对的脊椎假体部件，确定所述试验体与所述标记杆之间的相对位置，以及基于所确定的相对位置来选择用于植入所述目标解剖结构的部件。
