摘要：
A cervical plate apparatus includes a cervical plate body having a plurality of screw receiving passages defined therethrough. Received about each of the passages is a zero-step locking member which is operatively associated with the passage and configured to automatically lock the head of the screw in place within the passage when the screw is seated within the passage to attach the cervical plate to the cervical vertebrae. The locking member is selectively movable to an unlocked position. A retention structure is configured to retain the locking member in either the unlocked or locked position without further engagement of the locking member by a surgeon, so that when the locking member has been moved to the unlocked position, it is held in that position so that the surgeon can then remove the screw or screws without having to simultaneously hold the locking member in a retracted position.
