Abstract: An improved cage that has an anchoring system and method of use thereof. The anchoring system has movable/expandable jaw portions that can expand vertically (i.e., upward and downward relative to the respective superior and inferior surfaces of the cage) so that the cage can be more securely implanted in position. The superior and inferior expandable portions of the anchoring system move vertically by the rotation of one or more spindles that is incorporated in the jaw mechanism (and/or by the rotation of a lead screw that is incorporated in the cage). In some embodiments, the medical implant (such as a cage) is itself non-expandable (i.e., the height of the medical implant does not change). In other embodiments, the medical implant (such as a cage) can be expanded independently of the anchoring system.

Abstract: A kit for orthopedics, preferably for osteosynthesis, has a mechanical fixing system that includes a plate for straddling between two bone fragments and fixing screws for fixing the plate to the two bone fragments.

The heads of the fixing screws have a upper surfaces with a recessed and shaped mark for coupling with the tip of a screwing tool and external side walls with a thread for engaging a gripping tool. When the conical collar is inserted into a corresponding conical through hole of the plate, the head protrudes outwardly from the plate.

The first and second plates secure with the sternum across the opening. The implant, in an insertion shape, inserts through the first and second plates and into the sternum across the opening, and then, upon a movement toward a natural shape, holds the opening closed while interconnecting the first and second plates. The sternal closure system alternatively includes an implant with a bridge having first and second apertures and first and second legs extending from the bridge. The implant, in an insertion shape, inserts into the sternum across the opening, and then, upon a movement toward a natural shape, holds the opening in the sternum closed.
