  • Patent number: 8986305
    Abstract: A method of performing vertebral facet fusion by lateral approach and related devices. The lateral approach to facet fusion involves identifying the lateral mass and introducing any of the fixation methods known or described herein laterally at one or more facets through the use of a Kirschner wire guide, a cannulated bone drill and cooperatively cannulated staple guide. A surgical bone staple have a perforated bridge is used across the lateral facet joint where fixation is required. Where fusion is desired, a bone screw have lateral perforations of the shank is inserted through the cannulated staple guide and bridge perforation at the joint to promote fusion. A staple cap and graft container for overlay grafting may be utilized for additional fusion. The method involves less surgical time, reduced blood loss and discomfort for the patient as compared to the posterior approach.

  • Patent number: 8945192
    Abstract: Implants for forming a positive connection with human or animal parts include a material, such as thermoplastics and thixotropic materials, that can be liquefied by means of mechanical energy. The implants are brought into contact with the tissue part, are subjected to the action of ultrasonic energy while being pressed against the tissue part. The liquefiable material liquefies and is pressed into openings or surface asperities of the tissue part so that, once solidified, the implant is positively joined thereto. The implantation involves the use of an implantation device that includes a generator, an oscillating element, and a resonator. The generator causes the oscillating element to mechanically oscillate, and the element transmits the oscillations to the resonator. The resonator is used to press the implant against the tissue part to transmit oscillations to the implant.

  • Patent number: 8894651
    Abstract: A method of performing vertebral facet fusion by lateral approach and related devices. The lateral approach to facet fusion involves identifying the lateral mass and then introducing any of the fixation methods known or described herein laterally at one or more facets through the use of a hollow cannula. A surgical bone staple have a perforated bridge is used across the lateral facet joint where fixation is required. Where fusion is desired, a bone screw have lateral perforations of the shank is inserted through the bridge perforation at the joint to promote fusion. The staple and screw may be used in conjunction with one another or individually. The facet joint may be distracted prior to fixation to increase the foraminal space and decompress the neural structures to relieve pain. The method involves less surgical time, reduced blood loss and discomfort for the patient as compared to the posterior approach.

  • Patent number: 8454665
    Abstract: A multi-purpose bone plate system comprises a set of sterile malleable bone plates, an adjustable bending and contouring tower with adjustable angulation and compression slots and a set of bone plates with angulation and compression slots positioned at pre-selected locations to aid three-dimensional shaping of the bone plate. The surgeon inserts the sterile bone plate template to surround the fractured bone and works the template to acquire the physical shape of the fractured bone, inserts the template into the tower to set the adjustable angulation and compression slots of the tower. Now a symmetrical bone plate is inserted into the tower and bent to a shape that replicates the shape of the bone plate. The three-dimensionally shaped bone plate is sterilized and is attached by screws or nails surrounding the fractured bone segment and provides support to fractured bone segments during healing of the bone.
