Abstract
Systems and methods are provided that include a plate member engageable to the spinal column with an anchor assembly. The anchor assembly includes a coupling member having a post extending through at least one opening of the plate member and an anchor member pivotally captured in a receiver member of the coupling member below a lower surface of the plate member. A locking member secures the plate member to the coupling member. The coupling member includes an extended post with a proximal removable portion. The extended post facilitates placement of the plate member in position relative to the anchor assembly when engaged to the patient and be employed to reduce the plate member toward the anchor assembly when engaged to a vertebra.
