  • Patent number: 11464554
    Abstract: The present invention includes devices, systems and methods for the storage, retrieval and placement of plates having wedges. A wedge plate tray includes an upper portion and at least one recessed portion, the recessed portion including a cavity sized to house the wedge and an additional cavity sized to accommodate placement and movement of an arm of an insertion instrument. The insertion instrument includes two arms connected at a hinge, a tip of each arm including a mating connector sized to engage a complementary mating connector on the wedge. In one embodiment of the method, the insertion instrument can be used to place the wedge plate in an osteotomy and where the wedge is a mobile wedge, a plate component can be adjusted to a desired position for securement while using the insertion instrument to hold the wedge in place in the osteotomy.

  • Patent number: 9393029
    Abstract: A device for guiding a drilling tool to form an opening in a bone, includes a body extending from a distal end to a proximal end, the body including a lumen extending therethrough, the lumen being sized and shaped to slidably accommodate a guidewire therein and a plurality of arms extending proximally from the proximal end, the arms being disposed about the lumen with a gripping surface of each arm being spaced radially from an axis of the guide wire lumen by a distance corresponding to a thickness of a guidewire to be received therein, the gripping surfaces gripping the guidewire to maintain a portion thereof extending proximally of the lumen along the axis of the lumen.

  • Patent number: 9381054
    Abstract: A bone fixation device comprises an elongated body extending from a head at a proximal end to a shaft at a distal end along a central longitudinal axis. A slotted opening extends distally into the head by a predetermined distance, the opening defining a spring portion on a lateral side thereof, the spring portion being biased toward the central longitudinal axis and configured to be deflectable away from the central longitudinal axis upon application of a radially expansive force thereto.

  • Patent number: 9155582
    Abstract: A device for facilitating implantation of an intramedullary nail includes a coupling portion extending from a first end configured to couple to a proximal end of an intramedullary nail to a joint portion and a radiolucent handle coupled to the joint portion and extending distally therefrom along a path which, when the coupling portion is coupled to an intramedullary nail in a desired orientation, extends substantially parallel to a longitudinal axis of a proximal portion of the nail, the radiolucent part including first and second radiopaque markers positioned and oriented so that, when the nail is coupled to the coupling portion in the desired orientation, the first and second markers align with edges of the proximal portion of the nail.

  • Publication number: 20140081281
    Abstract: An aiming device for bone fixation includes (a) a handle extending from a first end to a second end along a longitudinal axis, (b) a guide arm connected to the second end of the handle and having an opening extending therethrough, the guide arm being connected to a protection sleeve; and (c) a drill guide configured and dimensioned for insertion through the opening of the guide arm. The drill guide has first and second guide channels extending therethrough to guide an insertion of a guide wire into a bone. The drill guide is movable between a first position wherein the drill guide is axially and rotationally movable relative to the guide arm to a second position wherein the drill guide is axially and rotationally locked relative to the guide arm.
