    摘要: A retention system for maintaining a screw to a vertebral plate. One or more screws extend through apertures within the vertebral plate. A cavity is positioned adjacent to and overlaps into the aperture. A ring is positioned within the cavity and held in position by a cap. The cap attaches to the plate to prevent removal of the ring. The ring is deflectable between a first shape to allow the screw to be inserted and removed from the aperture, and a second shape to prevent screw back-out from the aperture. A method of using the system is also included and comprises positioning the ring within a cavity in the plate, maintaining the position of the ring to the plate by attaching a cap, inserting a screw through the aperture and attaching the plate to a vertebral member, and positioning the ring over the screw head and preventing the screw from backing-out.

    摘要: An anterior fixation system includes a plate defining a plurality of screw holes, a number of screws and a number of locking assemblies for fixing the screws to the plate. The system includes two bone screws, a fixed angle screw and a variable angle screw, that are configured to extend through the same screw openings in the fixation plate. The surgeon can select either the fixed or variable angled screws to be implanted with a single plate and can place either type of screw into any of the screw holes along the plate. The fixation plate can include several screw holes in various patterns that provide the surgeon with great flexibility in the placement of bone screws depending upon the spinal anatomy and pathology. Also contemplated is a locking assembly to lock one or more bone screws within a respective screw hole.

    摘要: In one embodiment of the invention, an anterior fixation system includes a plate defining a plurality of screw holes, a number of screws and a number of locking assemblies for fixing the screws to the plate. The system includes two bone screws a fixed angle screw and a variable angle screw, that are configured to extend through the same screw openings in the fixation plate. The surgeon can select either the fixed or variable angled screws to be implanted with a single plate and can place either type of screw into any of the screw holes along the plate. The fixation plate according to the invention can include several screw holes in various patterns that provide the surgeon with great flexibility in the placement of bone screws depending upon the spinal anatomy and pathology. The invention further contemplates a locking assembly to lock one or more bone screws within a respective screw hole. In one embodiment, the locking assembly includes a washer that is held to the plate by a staked locking screw. The washer includes an outer surface that overlaps one or more screw holes. The washer is initially loosely held to the plate by the locking screw so that various tools and bone screws can be passed through the screw holes. In one embodiment of the washer, the washer includes cut-outs corresponding to the screw holes, along with a notch and key configuration for setting the locking washer in its locked configuration.

    摘要: A multi-axial screw assembly comprises a receiver, a base member, and a crown. The receiver comprises a channel for receiving a rod and an aperture extending from a bottom portion of the receiver. The base member comprises an aperture extending through the base member and an opening on a bottom portion of the base member. The base member is configured to couple to the receiver such that the aperture of the receiver is generally aligned with the aperture of the base member. The base member is rotatable relative to the receiver. The crown is received in the receiver and configured to mate to the base member. The crown has a mating feature configured to couple to the base member such that the crown rotates the base member when the crown is rotated.

    摘要: Skeletal stabilization systems include a base, a longitudinal member, and a retaining member. The base includes an engagement surface with a surface area that is positionable in contact with a bone to atraumatically or traumatically engage the base to the bone. The retaining member engages the base to retain the longitudinal member relative to the base so that the longitudinal member can provide a desired stabilization effect to one or more adjacent bony portions.
