  • Patent number: 6197064
    Abstract: An implant is provided for which has an outer bearing surface and an inner attachment surface. The outer bearing surface functions as ajoint contact surface for a reconstructed bone joint. The inner attachment surface contacts a bone and is attached thereto. The inner attachment surface of the implant is curvilinear from the anterior to the posterior area of the femur, and is also curvilinear from the medial to the lateral areas of the femur to approximates the shape of natural femur. The resection of the femur for accommodating the implant can be properly performed by a milling device employing one or more curvilinear milling bits.

  • Patent number: 6162225
    Abstract: A combination driver and bone screw assembly comprising a screw shank with a uniform diameter threaded portion, an unthreaded portion with a outwardly tapered end and a driving end portion of substantially wedge shaped configuration which can be engagably seated in a wedge shaped notch seat of a driver member. The driver member comprises a body, a drive head defining a wedge shaped notch seat secured to the body forming a shoulder and a drive collar mounted around the drive head and seated on the shoulder.In operation a bore is drilled in the patients bone with the top portion of the bore having a tapered geometry which widens from the diameter of the bore. The bone screw driving end portion is placed in the wedge shaped notch seat of a driver member and a drive collar is mounted around the driver drive head and engages the shoulder.

  • Patent number: 6099529
    Abstract: A bone screw assembly constructed of allograft bone comprising a screw shank with a uniform diameter threaded portion, an unthreaded portion with a outwardly tapered end terminating in a drive head defining a wedge shaped configuration to form an undercut for the drive head.In operation a bore is drilled in the two bone sections, with one bone section being over drilled with the top portion of the over drilled bore having a tapered geometry which widens from the diameter of the bore. The bone screw is driven into the previously cut bore in the bone sections until the tapered surface of the bore engages the tapered undercut surface of the screw.

  • Patent number: 6056754
    Abstract: A method and apparatus is provided for cutting bone. In one embodiment, a femur is resected by means of pattern plates having a cutting path with at least two continuous, non-coplanar guide surfaces. The cutting path has a similar profile to the interior profile of a femoral prosthesis. The cutting path guides a reciprocating, oscillating, or rotating cutting tool along a path for removing material from some or all of the distal femur to accept a distal femoral prosthesis. The cutting tool can be a cylindrical milling bit, and can even have a curvilinear profile to cut bone such that it has a three dimensional profile in cross section. Pattern plates can also be used to cut or remove material from other bones.

  • Patent number: 5643272
    Abstract: A method an apparatus for resecting a proximal tibia during a knee replacement operation is provided. The apparatus includes an ankle clamp, an alignment rod, a fixation head, cutting guide clamps having cutting guide slots therein, and a milling bit. The method includes the steps of attaching the ankle clamp about the ankle, interconnecting the distal end of the alignment rod with the ankle clamp, interconnecting the fixation head with the proximal end of the alignment rod, partially attaching the fixation head to the proximal tibia, aligning the alignment rod, completely attaching the fixation head to the proximal tibia, interconnecting the cutting guide clamps with the alignment rod, positioning the cutting guide clamps about the proximal tibia, securing the cutting guide clamps to the tibia at a proper location, removing the fixation head, placing the milling bit within the cutting guide slots, and cutting the proximal tibia with the milling bit.

  • Patent number: 5597379
    Abstract: The apparatus of the present invention includes a number of components including a guide body component, an extension block component, a rotating arm component, an extension rod component, and a tibial referencing component. The guide body component contacts the distal-most surface of the femur. Its location is based off of the posterior femoral condyles and the surface of the distal-most femoral resection or the unresected distal-most femoral surface. The rotating arm component is interconnected with the guide body and may rotate with respect thereto, thus allowing for the direct or indirect adjustment of the rotating alignment of cutting guides for resecting the distal femur. The rotating arm component carries arms with drill screw apertures which direct placement of drill holes in the femur which are used to attach a cutting guide to the femur.
