Abstract
A device, system and method for securing a plate to a bone. An anchor device has a screw (with a head portion) and a locking disc. The head portion includes a slotted wall defining a plurality of petals disposed around a central opening. The screw further includes an internal bore. The locking disc is rotatably disposed within the central opening, such that in a first rotational position the petals may flex inwardly, and in a second rotational position the petals are substantially prevented from flexing inwardly. A tool for manipulating the anchor device has a shaft with its end configured to mate with the internal bore of the screw to permit selective rotation of the screw, and a sleeve member rotatably and slideably mounted on the shaft having an end that mates with the locking disc to permit selective rotation of the disc.
