A spinal plate system and method for fixation of the human spine is provided. In an embodiment, the spinal fixation system includes a plate, a coupling member, a locking system for substantially locking the coupling member in a desired position, and an anchoring system to secure the coupling member in the locking system. The plate may have a hole that allows the coupling member to couple the plate with a bone. At least a portion of the coupling member may swivel in the hole so that a bottom end of the member may extend at a plurality of angles substantially oblique to the plate. The locking system may lock the coupling member in desired positions relative to the plate. The anchoring system may secure the coupling member in the locking system to inhibit the coupling system from detaching from the locking system when stressed. An assembly tool may be used to engage and disengage the anchoring system during the installation or removal of the spinal fixation system.

[ What is claimed is:] [1.]1. A bone plate system comprising:a plate configured to stabilize a bone structure;a hole passing through the plate;a ring positionable within the hole, the ring comprising a deflectable portion;a fastener positionable through the ring such that a head of the fastener engages the ring, the fastener configured to couple the plate to a bone; andwherein the deflectable portion of the ring is configured to deflect outwards when the head is initially positioned in the ring and wherein the deflectable portion is configured to deflect inwards after passage of a portion of the head into the ring to couple the fastener to the ring so that removal of the fastener from the plate is inhibited.
