  • Patent number: 9532817
    Abstract: An intramedullary nail has a scalloped compression slot so as to define a plurality of pockets and intersections between the pockets that are narrower than the pockets. Accordingly, a compression member can be inserted into a bone segment of a fractured bone and into the slot. The compression member can be wider than the intersections. A compression actuator can apply a force against the compression member that causes the compression member to translate across the intersections from pocket-to-pocket until the fracture has been approximated. Because the compression member is wider than the intersections, the compression slot retains the compression member and prevents distraction of the fracture.

  • Patent number: 9078676
    Abstract: A patella drilling system includes a clamp and a patella drill guide. The clamp includes an arm with a pointed tip that is received in a dimple on the surface of the patella drill guide and another arm with a bone-gripping member spaced from the tip. The clamp is used to hold the patella drill guide firmly against the resected posterior surface of the patella while the surgeon drills into the patella to form holes for mounting pegs on the implant. The clamp may allow the patella drill guide to be pivoted while clamped so that the orientations of the guide bores may be optimized. The system includes an optional cap that may be used on the pointed tip of the clamp to hold the implant firmly in place while the bone cement sets.

  • Patent number: RE46008
    Abstract: The present invention relates to a nail and fastener assembly for use in providing a stable construct for optimal fixation of the hindfoot and to methods for implanting the nail and fastener assembly. One embodiment of the nail and fastener assembly provides additional fixation, for example, in the form of one or more threaded bores, to hold the fasteners in a fixed position. Another embodiment provides angled bores to allow multi-planar and multi-axial implantation of the fasteners. In some instances, the fasteners may cross one or more articulating surfaces of the foot. For example, the fastener may traverse one or more of the calcaneo-cuboid and the talo-calcaneal articulating surfaces to aid in more secure stabilization of the hindfoot.
