    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.

    Abstract: Surgical techniques, instruments and systems for bone fusions and repairs (for example, phalangeal fusion) which allow alignment of small bones (for example, phalanges) without the use of guidewire and cannulated instrumentation such as, for example, drills and drivers, and cannulated screws. A drill/driver hybrid instrument (a combined drill/driver device) may be used in fusion of two small bones (for example, in interphalangeal fusion). One end of the hybrid instrument is provided with a plurality of flutes so that the instrument can be used as a drill to remove bone. The other end is shaped to mate with a device to be inserted intraarticularly (for example, interphalangeally), acting as a driver for that device.

  • Publication number: 20140277183
    Abstract: The present invention provides an orthopaedic implant including a base device having a device surface and a fixation material attached to at least one portion of the device surface. The fixation material is configured to provide a minimally sufficient adhesive force to resist natural pull out caused by forces acting on the base device after implantation and bone growth. Also provided is a method of manufacturing an orthopaedic implant. A base device with a device surface is provided and a minimally sufficient adhesive force, that can resist natural pull out caused by forces acting on the base device after implantation and bone growth, is determined. A proper amount of fixation material sufficient to provide an adhesive force equal to the minimally sufficient adhesive force is determined and fixation material is applied to the device. When the proper amount of fixation material is applied to the device surface, application is stopped.
