  • Publication number: 20210022807
    Abstract: A method of planning a procedure to fasten an implant to a bone includes displaying a model of the bone and a model of the implant on a display device. The model implant is positioned on the model bone in a desired implant position. A first boundary volume of a first fastener configured to fasten the prosthesis to the bone is also displayed on the display device. The first boundary volume represents a range of possible positions that the first fastener may have with respect to the prosthesis when fastened to the bone. The boundary volume may be used to determine a desired size, shape, and/or positioning of the fastener with respect to the bone.

  • Patent number: 10898270
    Abstract: A method for guiding implantation of a first prosthetic component includes determining, using a virtual model of a joint including first and second bones, a planned orientation of the first prosthetic component in the joint, applying a valgus/varus moment to the joint at a plurality of flexion positions of the joint, and recording positional data indicative of relative positions of the first bone and the second bone at the plurality of flexion positions of the joint. The method also includes calculating estimated separation distances between the first prosthetic component and a second prosthetic component, adjusting the planned orientation of the first prosthetic component in the joint in response to an error between the estimated separation distances and one or more desired separation distances, and guiding implantation of the first prosthetic component on the first bone in accordance with the adjusted planned orientation of the first prosthetic component.

  • Patent number: 10646278
    Abstract: A computer-implemented method determines an orientation parameter value of a prosthetic component. The method includes receiving a first desired separation distance between a first prosthetic component and a second prosthetic component at a first flexion position of a flexion joint and estimating a first estimated separation distance between the first prosthetic component and the second prosthetic component at the first flexion position of the joint for at least one potential orientation of the first prosthetic component. The method also includes determining a first orientation parameter value of the first prosthetic component by comparing the first estimated separation distance to the first desired separation distance and outputting the first orientation parameter value via a user interface.
