    • A pedicle screw is pre-connected to a longitudinal member by an articulation joint. The articulation range is through an angle extending at least from a 90° angle between the longitudinal axis of the pedicle screw and the longitudinal axis of the longitudinal member to an angle sufficiently near a coaxial orientation between those longitudinal axes to permit the first pedicle screw to be screwed into a pedicle of a first vertebra with the longitudinal member attached to the first pedicle screw. A lock fixes the longitudinal member to the first pedicle screw in a selected orientation. A second pedicle screw has an anchor joint with a lock for receiving and being fixed to the longitudinal member after the longitudinal member is rotated into engagement with the anchor joint. The pre-connection with sufficient articulation eliminates the need to connect the longitudinal member to one of the pedicle screws through an incision and assures proper alignment of any bend placed in the longitudinal member.
    • 椎弓根螺钉通过关节接合部预先连接到纵向构件。 关节运动范围通过在椎弓根螺钉的纵向轴线和纵向构件的纵向轴线之间至少从90°角延伸到在这些纵向轴线之间足够接近同轴定向的角度的角度,以允许第一椎弓根螺钉 被拧入第一椎骨的椎弓根,其中纵向构件附接到第一椎弓根螺钉。 锁定器将纵向构件以选定的方向固定到第一椎弓根螺钉。 第二椎弓根螺钉具有锚固接头,其具有用于在纵向构件旋转成与锚固接头接合之后用于接收并固定到纵向构件的锁。 具有足够关节的预连接消除了通过切口将纵向构件连接到椎弓根螺钉之一的需要,并且确保放置在纵向构件中的任何弯曲的适当对准。
