Abstract:
An anterior cervical plate system is provided. The plate is configured to receive bone screws for attachment to and immobilization of adjacent vertebrae of the spine. The system includes a lock configured to prevent the bone screws from backing out of the plate. The lock includes at least one blocking surface that is movable between a blocked configuration preventing the bone screw from backing out and an unblocked configuration allowing passage of the bone screw. The lock achieves a blocked position in a rotation of less than 90 degrees while maintaining or increasing a low-profile.

Claim (Index 1):
A bone plate system, comprising:\n a plate having at least one through hole configured to receive a bone screw for attaching the plate to bone; the plate having an upper surface and a lower surface interconnected by side surfaces; the plate includes a lock aperture adjacent to the at least one through hole; the lock aperture being configured to receive a lock at the upper surface and configured to receive a lock retainer at the lower surface; the upper surface of the plate includes a recess having a bottom surface; the lock aperture being formed in the location of the recess; a bone screw having a head portion connected to a shank portion; the bone screw being sized and configured for insertion into the through hole; a lock retainer connected to the plate and located inside the lock aperture; the lock retainer having a threaded inner surface; and a lock having a main body connected to a threaded post; the post being threadingly connected to the threaded inner surface of the lock retainer such that the lock is permitted to rotate with respect to the plate and, with rotation of the lock, to threadingly translate vertically with respect to the plate; wherein the lock has an unlocked position in which the main body of the lock does not cover the head of the bone screw inside the through hole permitting passage of the bone screw in or out of the through hole and a locked position in which at least part of the main body is above the head portion of the bone screw to prevent the bone screw from backing out of the through hole; wherein rotation of the lock with respect to the plate from the unlocked position to the locked position simultaneously moves the lock in a direction toward the plate and the main body toward the screw head; and wherein rotation of the lock with respect to the plate from the locked position to the unlocked position simultaneously moves the lock in a direction upwardly away from the plate and the main body away from the screw head.
