  • Patent number: 9814504
    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: 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: 9687282
    Abstract: An orthopedic plate system comprises a plurality of fasteners such as pegs or screws and a plate having two sets of holes for the fasteners. The first set of at least one hole includes internal threads that receive a fastener having a head which includes external threads that mate with the internal threads of the hole to lock the fastener at a fixed angle relative to the plate. The second set of at least one hole is devoid of internal threads and has a concavely rounded internal surface and which receives a convexly rounded external surface of a locking insert, which receives a variable axis fastener. The variable axis fastener causes the locking insert to expand to lock the variable axis fastener at a selected angle relative to the plate.

  • Patent number: 9474554
    Abstract: A cross connector assembly is provided. In one embodiment, the cross connector is configured to engage a pair of rods in a spinal implant assembly. In an exemplary embodiment, the cross connector assembly includes at least one elongated top member having a pair of hooked-shaped ends and a pair of sliding members configured to slideably engage the at least one elongated top member. The cross connector may further include an upper fastener and a lower fastener engaged with the upper fastener configured to translate upon rotation of the upper fastener and engage the sliding members, biasing them from a first position to a second position.

  • Publication number: 20160128734
    Abstract: Devices, systems and methods for connecting surgical screws together, which can be utilized to attach surgical screws in a variety of configurations, such as where the screws and/or attached tulip head components are not parallel or where a significant amount of anatomical variation creates widely divergent screw placement. Also disclosed are low profile crosslink arrangements having a high degree of strength and capable of providing an extremely strong connection to various components of a surgical screw.

  • Patent number: 9149313
    Abstract: An orthopedic plate has a portion with a curved bottom surface that is designed to extend longitudinally along the bone and change the inferior curve as it advances proximally along the bone from a shallower to a sharper radius and further spirals downward as the plate advances. The plate includes a set of tabs, offset from the longitudinal axis of the plate to provide for better pullout values. The ears may be located at the terminal portion of the plate or somewhat more intermediate to the terminus of the plate, depending on the intended application. A point in the center of the central screw hole can be used to define the origin of the plate, and the angles of the screw and/or pegs holes can be referenced with Z, Y, and Z coordinates relative to this central hole.
