  • Patent number: 12090058
    Abstract: An implant resection system for preparing an implant site to replace a defect in an articular surface of a first bone includes a guide configured to be coupled generally perpendicular to the first bone proximate to the defect. The guide includes a body portion defining a plurality of excision passageways. The excision passageways each define a generally cylindrical core pathway configured to extend generally perpendicular to the first bone which partially overlaps with an adjacent generally cylindrical core pathway. A projection associated with each of the plurality of the generally cylindrical core pathways defines a truncated cylindrical excision site extending through a portion of the articular surface. Each truncated cylindrical excision site partially overlaps with at least one adjacent truncated cylindrical excision site.

  • Patent number: 11944550
    Abstract: Provided is a system and method for providing a non-binding allograft subtalar joint implant for surgical implant into a person's foot proximate to the ankle. This system for repair includes at least one sterile non-binding allograft subtablar joint implant provided as a pre-formed allograft rod plug “ARP” having a diameter about equal to an average width of a canal between a person's talus and calcaneus bones, the ARP being resiliently compressible and flexible. When snuggly disposed between the person's talus and calcaneus bones, the ARP compresses during normal use of the person's foot and maintains the canal in an anatomically correct alignment and reduces a tendency for abnormal motion between the person's talus and calcaneus bones. An associated method of use is also provided.

  • Patent number: 7951163
    Abstract: A method for excising a portion of an articular surface using a retrograde procedure. An access tunnel is provided extending through a bone and to the articular surface. A central shaft is inserted through the access tunnel to the articular surface and a cutter is coupled to the central shaft. The cutter is coupled to the central shaft to allow the cutter to rotate with the central and to allow the cutter to be tiltable relative to the central shaft. The cutter is rotated and a retrograde force is applied to the cutter to urge the cutter into the articular surface.
