    Abstract: A surgical assistance system may obtain a pre-revision model of a bone of a patient. The pre-revision model of the bone represents a pre-revision state of the bone after a prior orthopedic surgery on the bone. In this example, an orthopedic prosthesis was attached to the bone during the prior orthopedic surgery. Additionally, the surgical assistance system may obtain intra-revision imaging data of the bone. The intra-revision imaging data represents an intra-revision state of the bone during the orthopedic revision surgery after removal of the orthopedic prosthesis from the bone. The surgical assistance system may determine, based on the intra revision imaging data, damaged and intact parts of the bone. The surgical assistance system may then generate a second intra-revision model of the bone by modifying the pre-revision model of the bone to exclude damaged parts of the bone.

    Abstract: An example method includes determining, by the one or more processors, an actual orientation of a surgical pin as installed in a bone of a patient; obtaining, by the one or more processors, a planned orientation of the surgical pin; determining, by the one or more processors and based on a comparison between the actual orientation of the surgical pin and the planned orientation of the surgical pin, whether the surgical pin was installed as planned; and responsive to determining that the surgical pin was not installed as planned, outputting, via a visualization device, virtual guidance to assist a surgeon in correcting the installation of the surgical pin.

    Abstract: Bone tracking during orthopedic surgical procedures is described herein. An anti-rotation base of a registration marker of a mixed reality surgery system includes a surface configured to rest on and bear against a surface of a glenoid of a patient. The anti-rotation base also includes a plurality of pin receptacles that each define a respective pin axis. The pin axis of a first pin receptacle of the plurality of pin receptacles is not parallel to the pin axis of a second pin receptacle of the plurality of pin receptacles. Additionally, the anti-rotation base includes a mounting receptacle configured to receive the registration marker.
