  • Patent number: 11039867
    Abstract: A calcaneal targeting device includes a guide body configured to target a corresponding calcaneal bone plate. The guide body includes at least one mounting opening that is configured to align with a corresponding mounting opening of the calcaneal bone plate, at least one targeting opening configured to align with a corresponding fixation opening of the calcaneal bone plate, and a guiding portion that includes a tali targeting opening and a first elongated opening that has a first length. The first elongated opening is configured to allow sliding of a guide wire across the first length and align the tali targeting opening with a sustentaculum tali.

  • Publication number: 20070083207
    Abstract: A bone fixation assembly and associated method. The bone fixation assembly includes a bone fastener having a shaft for engaging a bone, and a head connected to the shaft. The shaft defines a longitudinal first axis. The bone fastener also includes a plurality of external thread windings defining an outer surface of the head. The external thread windings are circumferentially interrupted by at least one slot defined on the outer surface. The slot is inclined at an angle relative to the first axis.

  • Publication number: 20060149251
    Abstract: A bone fixation system. The bone fixation system includes a fixation plate including at least one fixation hole, and at least one fastener, the fastener including a coupler and a shank for engaging a bone. The coupler is threadably engaged with the fixation hole. The shank is angulatably retained by the coupler and orientable relative to the fixation plate at a selectable angle.

  • Publication number: 20050277937
    Abstract: A plating system for bone includes a plate member. The plate member has a top surface and a bottom surface. A plurality of holes are defined by the plate member. Each of the holes extend between the top surface and the bottom surface along an axis. At least a first hole of the plurality of holes is a threaded hole and has a first dimension generally perpendicular to the axis and a second dimension generally perpendicular to the axis. The first dimension is greater than the second dimension.

  • Publication number: 20050113829
    Abstract: An external fixation device includes a frame assembly having a first arc segment and a second arc segment. The first arc segment is for interconnection to a first bone portion. The second arc segment is for interconnection to a second bone portion. The first arc segment is coupled to the second arc segment for relative rotation. The external fixation assembly additionally includes an articulating module. The articulating module includes a central member, a first pivot segment and a second pivot segment. The first pivot segment is coupled to the central member for driven rotation about a first pivot axis. The second pivot segment is coupled to the central member for driven rotation about a second pivot axis. The second pivot axis is substantially perpendicular to the first pivot axis.
