  • Publication number: 20210236183
    Abstract: The present invention relates to a series of orthopedic plates for use in repair of a bone. The plate has a Y-shaped profile or an X-shaped profile which includes an elongate central trunk with a complex contour and either one or two terminal pairs of arms that have a first arm and a second arm that form differing angles and lengths relative to the trunk portion of the plate. The arms include locking screw holes where the screws converge toward each other to provide for multiplanar fixation but which do not impinge.

  • Publication number: 20210236182
    Abstract: An orthopedic plate has a first end including a locking screw hole that receives a locking screw and spaced from that hole is a closed compression housing that extends from the bone-facing side of the plate and which receives a compression screw that forms an angle of from about 10° to about 70° with a longitudinal axis of the plate. The compression housing is not located on the medial line of the plate, but is peripheral to the medial line, either in the longitudinal or the medial direction of the plate.

  • Patent number: 10786288
    Abstract: An orthopedic plate and fastener system is provided for fixation of bones which has an implant that can selectably be used to achieve fixed angle and variable locking of the fasteners, as well as non-locking of the fasteners. The system includes a variable locking assembly that includes a locking insert, having threads which mates with internal threads of a through opening in the implant. The system also provides for locking fixed angle fixation, and non-locking variable angle fixation, all of which can be used with the threaded holes of the plates. The locking insert is provided on a ring driver, which is similar to or acts as the drill guide used with the locking fasteners of the present. Thus, the invention also relates to a method of enabling surgery where the surgeon can select the mode of fixation of fasteners between variable axis locking, variable axis non-locking, and fixed angle locking fixation, all utilizing the same fastener opening within the implant.

  • Patent number: 9962213
    Abstract: The present invention relates to an orthopedic fastener driver which can be used with a variable angle fixation system, and in particular in which the driver has a variable angle drive tip that is capable of screwing a fastener in an orthopedic plate assembly at a variable angle relative to the drive axis of the driver, and further wherein the driver has a drive mechanism including an interference clutch mechanism that disengages so as to limit the relative depth of the fastener in the plate assembly as to avoid driving the fastener or fastener assembly through the plate.

  • Publication number: 20170245870
    Abstract: A surgical drill guide for positioning, aligning, and of holes to be drilled in bone tissue has retaining means that holds the position and alignment of the drill guide body in a releasable manner with respect to a fastener hole in an orthopedic implant. The retaining means is a key guide that mates with a key way or key ways in or around a threaded locking hole of an orthopedic plate for alignment of a pilot hole and method of using the guide. The key guide has 2 to 8 projections that extend in the direction of the axis of the hole, such as hemi cylindrical projections, and the plate has a corresponding female key way that receives the retaining means. The invention also relates to a method of aligning a locking fastener in a plate at a desired angle relative to a bone by using a surgical guide having a key interface with the plate to position and align a pilot hole.

  • Patent number: 9730742
    Abstract: A locking mechanism assembly to allow locking of a fastener in an orthopedic implant having its axis at a variable angle relative to the axis of threaded through opening in the implant. The assembly includes a locking insert, having threads which mates with the threads of the through opening and which includes a smooth opening that forms a torque driving recess and an annular flange. A fixator has a head portion with external threads of a harder material than that which forms the through opening so that the threads of the fixator will deform the insert to lock the fixator in a desired position relative to the plate.

  • Patent number: 9668792
    Abstract: An assembly for surgically treating a chest-wall deformity may include an implantable stabilizer member, an implantable pectus bar and an implantable stopping member. The implantable stabilizer member may include first and second base parts and a channel defined by the first and second base parts. The stabilizer member may include first and second retaining bars extending between the first and second base parts and traversing the channel. The first and second base parts may be adapted to be secured to tissue of the chest wall. The implantable pectus bar may be receivable within the channel of the stabilizer member. The implantable stopping member may be adapted to be engaged with the pectus bar between the first and second retaining bars after the pectus bar is inserted into the channel to restrict movement of the pectus bar relative to the tissue.
