  • Patent number: 9597131
    Abstract: This invention provides a calcaneal plate implanted using a sinus tarsi approach and comprises an anterior section having two locking screw holes, an s-shaped posterior facet section having a four locking holes and which rounds toward the bone at both the inferior and superior edges and is reinforced at the superior edge, and a blade shaped posterior portion having three linearly aligned locking holes and terminating in a tapered portion. There is also, a drill guide assembly having a drill guide column inserted through a hole in a targeting guide and locking to one of the locking holes in the plate, and cannulated drill guide sleeves that lock into holes in the targeting guide in a spaced relation whereby when the targeting guide is locked into the plate, the targeting guide can be used as a handle and wherein locking screws can be implanted percutaneously.

  • Patent number: 9545278
    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: 20160128747
    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.

  • Publication number: 20150351816
    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.
