    摘要： A posterior fixation system includes a saddle member and an anchoring member. The anchoring member anchors the saddle member to bone. The saddle member includes a pair of upright portions that define a channel. The saddle member further has a hole therethrough bounded by an inner wall, and the hole forms a lower opening in the saddle member. The lower opening in the saddle member may contain angular cutouts placed symmetrically about the axis of the saddle to increase the allowable angulation of the bone screw in relationship to the axis of the saddle. The channel is adapted to receive an orthopedic rod, and the hole in the saddle member is adapted to receive the anchoring member. The saddle member and the anchoring member can be coupled so as to allow multi-axial movement of the members.

    摘要： Spinal spacers 20 are provided for fusion of a motion segment. The spacers include a load bearing member 21 having a wall 22 sized for engagement within a space between adjacent vertebrae to maintain the space and an effective amount of an osteogenic composition to stimulate osteoinduction. The osteogenic composition includes a substantially pure osteogenic factor in, a pharmaceutically acceptable carrier. In one embodiment the load bearing member includes a bone graft impregnated in an osteogenic composition. In another embodiment, the osteogenic composition 30 is packed within a chamber 25 defined in the graft. Any suitable configuration of a bone graft is contemplated, including bone dowels, D-shaped spacers and cortical rings. A spinal spacer 300 for engagement between vertebrae is also provided which includes a body 301 formed of a bone composition. The body 301 includes a first end 311, an opposite second 315 end, a superior face 335 defining a superior vertebral engaging surface 337 and an inferior face 338 defining an inferior vertebral engaging surface 340. At least one of the vertebral engaging surfaces defines a set of migration resistance grooves 350. Each of the grooves 350 includes a first face 355 defining an angle of no more than about 90 degrees relative to the engaging surface 340 and a second opposing sloped face 360. The first and second faces 355, 360 define an arcuate pocket 370 therebetween for trapping vertebral bone to resist migration of the spacer 300. In one embodiment, the grooves 350 are arranged in series in that all of the second faces 360 slope in the same direction.

    摘要： A orthopedic fixation system comprising a plate with an outwardly-extending member. A saddle may be mounted on the member and includes spaced-apart arms that form a channel to receive a rod. An engagement member may be mounted within the saddle to prevent escape of the rod. In one embodiment, the engagement member is attached to the saddle to apply a downward force on the rod and an upward force on the saddle to lift the saddle relative to the plate. A method of attaching an orthopedic rod is also included. In one embodiment, a rod is positioned within a channel in the saddle and a downward force is applied against the anchor which results in an upward force on the saddle to lift the saddle relative to the anchor.

    摘要： Embodiments of an orthopedic implant device and system, and methods for implanting them, are disclosed. The implant may include a receiver member having a channel for accommodating an elongated rod or other longitudinal member, a bone anchoring member such as a screw or hook, and a base member rotatable with respect to the receiver member for retaining the bone anchoring member in the receiver member. The base member is configured to allow at least two different degrees of maximum angulation of the bone anchoring member with respect to the receiver member. The number and relative direction of such angulations are independent of the orientation of the channel or other part of the receiving member.

    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： The present invention is directed to a system for anterior fixation of the spine that utilizes an elongated fixation plate. The plating system stabilizes the spine and promotes fusion and incorporation of a graft or implant in a portion of the spinal column. In one aspect of the invention, the fixation plate has a first end with a pair of holes. Bone screws extend through the holes to rigidly secure the plate to a first vertebra. The second end of the plate is provided with a pair of slots through which bone screws extend for engagement with a second vertebra. The screws extending through the slots are translatable in the slot to maintain compression of the spinal column portion. The plating system includes a retainer assembly that prevents screw back out. Methods and instruments relating to the plating system are also described.
