    Abstract: An example method includes obtaining one or more intraoperative images, wherein: a surgical site includes bones that are not substantially exposed through skin of the patient during the surgery, a connected K-wire is attached to one of the bones, an external portion of the connected K-wire is connected to a fixation device that is attached to the patient; performing a registration process system with corresponding positions in a virtual coordinate system; generating a visualization that includes the models of the bones superimposed on the surgical site; based on the changes to the positions of the external portion of the connected K-wire, updating positions of the models of the bones in the visualization to maintain correspondence between positions of the bones and the positions of the models of the bones.

    Abstract: A method comprises generating initial designs that represent an orthopedic prosthesis customized for a patient; generating alternative designs based on the initial designs, wherein the alternative designs represent the orthopedic prosthesis and generating the alterative designs comprises, for each initial design in the set of initial designs: applying an encoder model that generates a vector based on the initial design, wherein the encoder model is part of an autoencoder; generating a set of modified vectors by modifying one or more elements of the vector; applying a decoder model to the modified vectors to generate one or more of the alternative designs, wherein the decoder model is part of the autoencoder, and the alternative designs represent the orthopedic prosthesis; and selecting a design for the orthopedic prosthesis based from the initial designs or the alternative designs.
