Publication number: 20210353429Abstract: An allograft implant for fusing a sacroiliac joint (“SI Joint”), the allograft implant having a body consisting of allograft bone, the body comprising two opposing faces. A graft window is disposed between the two opposing faces, the graft window providing passage through the body between the two opposing faces. The graft window has a cross-sectional area that is about 35% to about 40% of a first cross-sectional area of the body, and about 60% of an area of each opposing face that makes contact with the sacrum or the ilium of the SI Joint.Type: ApplicationFiled: July 8, 2021Publication date: November 18, 2021Inventors: Sean LaNeve, Charles Girsch, Chris Girsch

Publication number: 20210353430Abstract: A surgical device (2) for extraction of a prosthetic component from a patient during surgery. The surgical device comprises a first component (8) having a female coupling portion at a first end, and a second end configured to be connected to one of a prosthetic component or a surgical extraction instrument. The first component further includes a retainer. The surgical device further comprises a second component (10) with a first end defining a male coupling portion, a stem (30, 130) extending from the male coupling portion, and a second end configured to be connected to the other of the prosthetic component or the surgical extraction instrument. The male coupling portion of the second component is configured to be disposed within the female coupling portion of the first component and retained within the female coupling portion by the retainer, with the stem of the second component extending away from the female coupling portion of the first component.Type: ApplicationFiled: October 3, 2019Publication date: November 18, 2021Inventors: JAMIE ATKIN, GRAEME DUTTON, GARY MOORE

Publication number: 20210353431Abstract: An implant localization device includes a coupler and a positioning system. The coupler is configured to removably engage an implant component to fix the positioning system in space relative to the implant component. The positioning system is in communication with a centralized computing system, whereby, due to the fixed spatial relationship between the positioning system and the implant component, via the coupler, and determinable changes in movement relative to a registered starting point, the centralized computing system is able to calculate a real-time position and orientation of the implant component. The centralized computing system is configured to synthesize data from a joint templating software program, a CAD software program, and the positioning system to provide real-time positional and orientation data to assist with extraction and placement of the implant component. Robotics and reference markers may be used to further automate and/or enhance the accuracy and efficiency of the system.Type: ApplicationFiled: May 16, 2021Publication date: November 18, 2021Inventor: Jeffrey Wilde

Publication number: 20210353432Abstract: Disclosed is a tool set and an associated method for removing a prosthetic implant. Although the tools in the tool set can be used to remove a variety of different prosthetic implants, it finds particular application in the removal of femoral implants. In one embodiment, both lateral and medial tools are utilized. The lateral tool includes a generally arcuate shape with upstanding sidewalls that define an arcuate interior. The lateral tool is thus dimensioned to follow the contour of the lateral side of a femoral implant. The medial tool includes opposing side walls that define an interior opening. The opening is sized to receive the neck of the femoral implant, thereby allowing the tool to closely follow the medial bone/implant interface. In another embodiment, a J-shaped tool and an L-shaped tool are utilized to cut below an undercut of an femoral implant. The tools in the tool set can work together or individually.Type: ApplicationFiled: July 28, 2021Publication date: November 18, 2021Inventor: Jose S. Rivera, JR.

Publication number: 20210353433Abstract: A system for use during an orthopaedic surgical procedure includes a femoral broach, an acetabular cup component, and an acetabular alignment guide. The femoral broach includes a mounting post positioned at a superior end of an elongated body. The cup component includes a distal rim and a curved surface extending inwardly from the rim to define a cavity. The alignment guide includes a distal end configured to be coupled to the mounting post and a proximal end configured to be coupled to the distal rim. When coupled to the femoral broach, the guide instrument is sized to orient the acetabular cup component relative to the femoral broach. The acetabular cup component may be a prosthetic cup component or a trial instrument corresponding to the prosthetic cup component.Type: ApplicationFiled: May 15, 2020Publication date: November 18, 2021Inventors: Daniel N. Huff, Thomas S. Camino

Publication number: 20210353434Abstract: A multimodal abrading device for preparing a sacroiliac joint (“SI Joint”) to receive a graft implant. The abrading device comprises an abrading head having abrading surfaces on a first pair of opposing sides, the abrading surfaces configured for decorticating the cortical bone of the SI Joint. The abrading head further comprises an open tip having a cutting edge configured to cut bone tissue in the SI Joint.Type: ApplicationFiled: July 8, 2021Publication date: November 18, 2021Inventors: Sean LaNeve, Charles Girsch, Chris Girsch

Publication number: 20210353435Abstract: A method for forming and abrading an implant void in a sacroiliac joint (“SI Joint”) without the use of a rotary cutting instrument. The method incorporates a multimodal abrading device having abrading surfaces on opposing sides and an open tip comprising a cutting edge. The method includes the step of using the abrading head to cut bone tissue from the SI Joint at an insertion point while simultaneously using the abrading surfaces to decorticate the cortical bone at the insertion point.Type: ApplicationFiled: July 9, 2021Publication date: November 18, 2021Inventors: Sean LaNeve, Charles Girsch, Chris Girsch, Dwayne Polzer
