  • Publication number: 20140081274
    Abstract: An instrument for preparing bone. The instrument includes a medial side having a plurality of extraction teeth extending over at least a portion of the medial side and an anterior side having a plurality of compaction teeth extending over at least a portion of the anterior side. The instrument further includes a lateral side having a plurality of extraction teeth extending over at least a portion of the lateral side and a posterior side having a plurality of compaction teeth extending over at least a portion of the anterior side. The medial side and lateral side also include a plurality of chip breakers extending over at least one of the plurality of extraction teeth, the chip breakers sized and shaped so as to evacuate bone from the instrument.

  • Publication number: 20060155289
    Abstract: A device for reaming of a bone cavity or a channel of a hollow bone has an elongated, hollow shaft, a first end of which is adapted to be mounted to a rotary drive means in an angularly stable fashion. The device has a spindle, which is borne rotatably within the shaft and has a first end which extends to the mounting-end of the shaft and a second end which extends beyond the other end of the shaft. The first end of spindle is adapted for a rotary connection to a drive spindle of the rotary device means. A flexible, elongated member is provided which is, at its first end, laterally connectable to the second end of spindle, and a profile member made of a hard material located at the other end of the flexible member.

  • Patent number: 6296647
    Abstract: An instrument for the positioning of an implant into the human spine, as a replacement for one or more diseased vertebra bodies has vertebra body plates attachable to the healthy vertebra bodies. Distraction rods are provided which at one end are attachable to a vertebra body plate. Two U-shaped parts having limbs which telescopically cooperate and form a tubular housing around the attached distraction rods. The U-shaped parts comprise inner sections which are supported on the distraction rods. A distraction instrument which is connectable to the other ends of the distraction rods is used for exerting a force onto the rods transversely to their longitudinal direction.

  • Patent number: 6106557
    Abstract: A reconstruction system for vertebra, with at least one annular middle body and two annular end bodies. The end surfaces of the middle body and of the end bodies are formed such that the bodies may be stacked over one another and one end surface of the end bodies comprises a receiving section. The system includes two approximately right-angled vertebra body plates having a pair of limbs. One limb is formed such that in a direction perpendicular to the axis of an end body, it is insertable into the receiving section in a manner such that the one limb is prevented from moving away from the end body in the direction of the axis. The other limb comprises at least one bore for a bone screw and at least one threaded bore. A connection plate is provided, which at the ends comprises openings for connection to the other limb of each vertebra body plate via a screw.

  • Patent number: 5326360
    Abstract: An expandable endoprosthesis for a joint and adjacent bone parts has first and second joint component parts. The second component has a part at one end thereof for a portion of a joint. The second component has a telescoping stem coupled to its joint part for attachment to a long bone. The telescoping stem has an inner and an outer member axially adjustable with respect to one another by means of a threaded spindle and a threaded spindle nut attached respectively to either the inner or outer member. A pinion gear is attached to either the spindle or spindle nut for rotation therewith. An indexing system is provided to rotate the pinion a predetermined amount upon movement of the first and second joint components towards one another after implantation and thereby lengthen the second joint component stem.
