  • Publication number: 20110054614
    Abstract: There is provided an implant retaining device, which has the effect of preventing an intervertebral implant from jutting out of the receiving bed. The implant retaining device generally includes a plate having at least one throughbore to receive a screw, and a screw for securing the plate to the vertebrae. The plate may be dimensioned to cover a portion of the opening of a receiving bed, and thus, need only be secured to a single vertebral body. In an alternate embodiment, the plate may be used during bone fracture correction procedures to prevent a bone screw from backing out of engagement with adjacent bone sections. A method of retaining an intervertebral implant using the device is also provided.

  • Publication number: 20110040334
    Abstract: An implant unit used in surgery has a body made from osteogenic implantable material and including an implant portion and a retaining portion, which is coupled to and extends transversely to the implant portion. The retaining portion is attached to the sidewall of the adjoining vertebral body or mammal bone to prevent displacement of the implant portion relative to the vertebral body or mammal bone and to accelerate fusion therebetween.

  • Publication number: 20100211058
    Abstract: Bone substitute materials have been developed that become flowable upon heating. In order to use these new materials in the special environment of an operating room, methods and devices have been developed to conveniently and sterilely heat samples of the material as the material is being implanted into a patient. Inventive heating devices include cannulas with a heated tip and devices similar to a hot melt glue gun. Therefore, the material is heated for only a short time preventing the degradation of biological components of the material.

  • Patent number: 7726002
    Abstract: A cortical bone implant is formed of two or more planks of bone which are connected with one or more offset pins. The pins may be right circular cylinders inserted into a corresponding offset bore which offset bends the inserted pin. The bending creates compression and tensile loads in the pin which loads creates friction compression forces on the planks connecting them to the pins by friction. The pins may have different shapes to form offset configurations in place of the offset bores for friction attachment to the planks. The implants may be formed of flat or L-shaped planks or bones formed into other shapes including interlocking arrangements. Processes and fixtures are disclosed for forming the pins, planks and implants. Various embodiments of the pins, planks, implants and processes are disclosed.

  • Patent number: 7448264
    Abstract: A non-destructive method for evaluating the strength of cancellous bone includes the steps of performing at least two of the following tests on each cancellous bone of a population of cancellous bones: a manual compression test, an apparent density test, and an appearance test; determining a compressive strength for each cancellous bone based on the two tests performed; comparing the determined compressive strength of each cancellous bone against a predetermined compressive strength requirement; and, eliminating a subset of cancellous bone from the population of cancellous bone, which subset of cancellous bone fails to meet the predetermined compressive strength requirement.

  • Patent number: 6706067
    Abstract: A C-shaped or ring shaped implant formed of cortical bone has its C-shaped or inner channel filled with a bone promoting material which is preferably demineralized bone fibers formed as a flexible wet sheet or may be cancellous bone, pressed bone fibers formed from demineralized cortical bone chips soaked in acid, or a flex material formed of demineralized bone growth promoting bone fibers. The discrete bone filler element may be secured by a bonding agent, pins or screws, metal, polymer or bone material. The bone filler material is preferably bonded by filling a section of a long bone medullary cavity with wet bone fibers and then drying the fibers to bond them to the outer bone. A filled bone ring may be sliced to form annular filled sections which are then divided into mirror image C-shaped halves each forming an implant. Flex material of compressed bone fibers may be formed with an opening shaped to receive a cortical bone implant element having a C-shaped channel.

  • Publication number: 20030083747
    Abstract: Spinal and other implants may be bone or synthetic material shaped as rings, C-shaped or rectangular and so on and also may have serrated wedge shaped top and bottom surfaces to match the disc space lordosis of adjacent ertebra and so on. The implants have one or more recesses aligned in an insertion direction at either or both outer peripheral sides of the implant. In a ring implant, e.g., formed from a transverse slice of the diaphysis of a long bone or otherwise, the recesses are aligned overlying the opposing sides of the ring parallel to the insertion direction, which sides are stronger than the more central region overlying and aligned with a central chamber in the implant. The alignment ith the opposing sides minimizes damage to the implant at the weaker more central region in response to implant insertion forces.

  • Patent number: 6530955
    Abstract: A ramp-shaped intervertebral implant is disclosed. The implant has a body having a first end, a second end, a top surface and a bottom surface. At least one of the top and bottom surfaces is tapered and converges towards the second end of the body. An opening extends through the body and has one end opening onto the top surface of the implant and the other end opening onto the bottom surface of the implant. The implant can be formed from the diaphysis or metaphysis of a long bone, wherein the intramedullary canal of the long bone defines the opening. Alternately, the implant can be made from any biocompatible material having the requisite strength requirement.

  • Patent number: 6368322
    Abstract: An interference screw suitable for surgical use is provided. The interference screw is constructed from bone and includes an elongated body having an outer threaded surface, a tapered insertion end and a central throughbore. Insertion tool engaging structure is formed along the walls defining the throughbore. The insertion tool engaging structure extends from the proximal end of the elongated body over a substantial portion of the length of the elongated body. The insertion tool engaging structure functions to distribute the forces required to insert the interference screw throughout the body of the interference screw to prevent fracturing of the interference screw during insertion into bone.
