具有延展的多轴向锚定组件的脊柱植入物及方法
摘要：
提供了系统和方法，包括可用锚定组件(20、320、420)啮合至脊柱的板元件(120、140、160、180)。锚定组件(20、320、420)包括联接元件(30、130、330、430)，它具有延伸通过板元件(120、140、160、180)至少一个开口的杆部(32、332、432)和可在板元件(120、140、160、180)下表面的下面枢转接纳在联接元件(30、130、330、430)的接纳部分(34、334、434)中的锚定元件(70)。锁定元件(90)可将板元件(120、140、160、180)固定于联接元件(30、130、330、430)。联接元件(30、130、330、430)可包括具有近端可除去部分的延伸杆部(332、432)。一旦啮合于患者，延伸杆部(332、432)有利于板元件(120、140、160、180)在相对于锚定组件(20、320、420)的位置中的放置，一旦啮合至椎骨，则可用于向锚定组件(20、320、420)紧缩板元件(120、140、160、180)。
摘要（英）：

Systems and methods are provided that include a plate member (120, 140, 160, 180) engageable to the spinal column with an anchor assembly (20, 320, 420). The anchor assembly (20, 320, 420) includes a coupling member (30, 130, 330, 430) having a post (32, 332, 432) extending through at least one opening of the plate member (120, 140, 160, 180) and an anchor member (70) pivotally captured in a receiver portion (34, 334, 434) of the coupling member (30, 130, 330, 430) below a lower surface of the plate member (120, 140, 160, 180). A locking member (90) secures the plate member (120, 140, 160, 180) to the coupling member (30, 130, 330, 430). The coupling member (30, 130, 330, 430) may include an extended post (332, 432) with a proximal removable portion. The extended post (332, 432) facilitates placement of the plate member (120, 140, 160, 180) in position relative to the anchor assembly (20, 320, 420) when engaged to the patient and may be employed to reduce the plate member (120, 140, 160, 180) toward the anchor assembly (20, 320, 420) when engaged to a vertebra.
