Abstract:
An embodiment of the invention provides for a system, such as a cervical plate fusion system, that has mechanisms for preventing bone anchors (e.g., screws, pins, and the like) from backing out of the plate. The system prevents both counter-rotation of the screw and axial backing out of the screw. Other embodiments are described herein.

Claim (Index 1):
An orthopedic fusion system comprising:\n a plate that includes a first aperture; a single-piece monolithic resilient member included in a first cavity that directly contacts the first aperture, the resilient member including a first arm connected to a first end having a first fin and a second arm connected to a second end having a second fin; and a screw including a lip, which is coupled to a beveled shoulder, and a toothed wheel having first and second teeth; wherein (a) the resilient member is seperably coupled to the plate and within the first cavity; (b) the first cavity includes first and second channels that respectively include first and second portions of the first and second ends; (c) the first and second fins respectively project into the first aperture; (d) the first fin has a first angled leading edge and a first trailing edge, the first angled leading edge of the first fin being non-orthogonally connected to the first arm; (e) the first tooth has a first angled leading edge and a first trailing edge, the first angled leading edge of the first tooth being non-orthogonal to a radius from a tip of the first angled leading edge of the first tooth to a long axis of the screw; and (f) the first fin is sized to be received between the first and second teeth of the toothed wheel; wherein the system is configured such that (g) in a partially implanted position the screw is inserted into the first aperture and the beveled shoulder is actively deflecting the first fin medially and the second fin laterally; and (h) in a fully implanted position (1) the screw is inserted into the first aperture such that the screw is prevented from backing out of the first aperture by the first and second fins that have snapped back into the first aperture to intercept the lip when the screws travels axially away from patient bone in which it is implanted, and (2) the toothed wheel is allowed to rotate but is prevented from counter-rotating because the first trailing edge of the first fin is lodged against the first trailing edge of the first tooth.
