  • Bone screw washer
    Patent number: 8721694
    Abstract: A washer for use with a bone screw in the reduction and fixation of bone fragments includes a frusto-conical body having a leading end, a trailing end, an exterior surface and an interior surface. A central bore defined by the interior surface for insertion of a bone screw extends longitudinally through the washer. The interior surface is tapered resulting in the central bore's diameter being larger at the trailing end than at the leading end. The washer, when used in combination with a compression bone screw, improves seating of the bone screw head in the bone and results in enhanced compression.

  • INTERBODY SPINAL IMPLANT HAVING A ROUGHENED SURFACE TOPOGRAPHY
    Publication number: 20140114421
    Abstract: An interbody spinal implant including a body having a top surface, a bottom surface, opposing lateral sides, opposing anterior and posterior portions, a substantially hollow center, and a single vertical aperture. The single vertical aperture extends from the top surface to the bottom surface, has a size and shape predetermined to maximize the surface area of the top surface and the bottom surface available proximate the anterior and posterior portions while maximizing both radiographic visualization and access to the substantially hollow center, and defines a transverse rim.

  • TELEVIEWER IMAGE WOOD-GRAIN REDUCTION TECHNIQUES
    Publication number: 20140104978
    Abstract: Measurements made by a transducer assembly for downhole imaging are affected by reverberations between the transducer and the window on the outside of the assembly. The reverberations result in a stationary noise on the image. Hardware solutions to improve signal-to-noise ratio includes using a composite transducer, adjusting the distance between the transducer and the window. SNR can also be improved by processing techniques that include stacking, fitting a sinusoid to the reverberation, by envelope peak detection, and by applying a notch filter.

  • IMPLANTS WITH SELF-DEPLOYING ANCHORS
    Publication number: 20140094921
    Abstract: A spinal implant having a top surface, a bottom surface, opposing lateral sides, and opposing anterior and posterior portions. At least one of the top surface and bottom surface has a roughened surface topography, without sharp teeth that risk damage to bone structures, adapted to grip bone through friction generated when the implant is placed between two vertebrae and to inhibit migration of the implant. At least one of the top surface and the bottom surface also includes at least one self-deploying anchor having an expulsion tab and a bone-engaging tip that causes the implant to resist expulsion once the expulsion tab is deployed.

  • TRAPEZIUM IMPLANT FOR THUMB AND METHOD
    Publication number: 20140088723
    Abstract: An implant for the trapezium of the thumb carpometacarpal (CMC) joint comprising an integral elastomeric member configured to include a body portion having a tapered neck, having extending from one end thereof an elongated, longitudinally extending tapered portion adapted to be embedded into a reamed out-channel in the thumb metacarpal bone. After implantation, in the preferred embodiment of the method according to the invention, a segment of a nearby tendon, for example, the APL or FCR tendons, may be wrapped around the tapered neck of the implant to secure it in position, thereby forming a reinforced structure to inhibit dislocation of the prosthesis. However, in other methods, various other securing elements, including, but not limited to acellular matrices, may be used to retain the implant in position.
