Abstract: Techniques are described for determining a pre-morbid shape of an anatomical object. A method includes receiving first image data of a first anatomical structure and second image data of a second anatomical structure. The first and second anatomical structures are anatomically related. The method includes determining a first shape model based on the first image data and a joint statistical shape model (SSM). The method includes determining a second shape model based on the first shape model, the first image data, and the second image data, the second shape model including a second estimated shape of the first anatomical structure and a second estimated shape for the second anatomical structure. The method includes generating anatomical information indicative of the pre-morbid shape of at least the second anatomical structure based on the second shape model.

Abstract: Techniques are described for identifying bone areas for removal during a medical procedure. Processing circuitry may generate a virtual model of an anatomical object with the bone areas removed and one or more indications for the bone areas that are to be removed. During surgery, the processing circuitry may receive image data and update the one or more indications as the bone areas are removed. The processing circuitry may generate the virtual model and the bone areas for visual overlay on the actual anatomical object.

Abstract: Techniques and systems are described for mixed reality (MR) guidance of an ultrasound probe. A system may obtain reference data depicting a bone of a patient; determine a physical location of an ultrasound probe; generate, based on first ultrasound data generated by the ultrasound probe, registration data that registers virtual locations on the bone of the patient as depicted in the reference data with corresponding physical locations on the bone of the patient; generate virtual guidance based on the reference data, the registration data, and the physical location of the ultrasound probe, wherein the virtual guidance provides guidance to a clinician regarding how the ultrasound probe is positioned relative to a target position at which the ultrasound probe is able to generate second, ultrasound data that provides information regarding a soft tissue structure of the patient; and cause a MR visualization device to output the virtual guidance to the clinician.

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 that generates registration data for mapping positions on the external portion of the connected K-wire in the real-world coordinate 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 surgical assistance system obtains patient-specific values of a plurality of physical characteristics of a humeral bone of a patient. The surgical assistance system predicts, based on the patient-specific values, a humeral prosthesis (202) for the patient from among a plurality of humeral prostheses, wherein the predicted humeral prosthesis has a filling ratio less than a remodeling threshold for the patient. The filling ratio of the humeral prosthesis is a ratio of (i) a radial distance from a lengthwise central axis of a stem (206) of the humeral prosthesis to an outer surface of the stem, to (ii) a radial distance from the lengthwise central axis of the stem to an inner surface of the intramedullary canal (208) of a humerus of the patient. The remodeling threshold for the patient is a filling ratio above which the humeral prosthesis would cause remodeling in the patient..

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: A computing system obtains an information model specifying a first surgical plan for an orthopedic surgery to be performed on a patient. Additionally, the computing system modifies the first surgical plan during an intraoperative phase of the orthopedic surgery to generate a second surgical plan. During the intraoperative phase of the orthopedic surgery, a visualization device may present a visualization for display that is based on the second surgical plan.
