    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: Techniques and systems are described for planning shoulder stability enhancement surgeries. A computing system may determine a size of a predicted premorbid glenoid bone of the patient of a patient, a size of a Bankart lesion on a morbid glenoid bone of the patient, and a size of a geodesic surface on a 3-dimensional model of a predicted premorbid humerus of the patient. The geodesic surface is defined at least in part by a projected medial border of a Hill-Sachs lesion on a morbid humerus and a projected medial border of a footprint of a humeral head of the morbid humerus. The computing system may determine, based on the three areal sizes, whether bone loss of the patient involves joint engagement. The computing system may output an indication of whether a shoulder stability enhancement surgery that includes a bone graft is recommended for the patient.

    Abstract: A surgical planning system for use in surgical procedures to repair an anatomy of interest includes a preplanning system to generate a virtual surgical plan and a mixed reality system that includes a visualization device wearable by a user to view the virtual surgical plan projected in a real environment. The virtual surgical plan includes a 3D virtual model of the anatomy of interest. When wearing the visualization device, the user can align the 3D virtual model with the real anatomy of interest, thereby achieving a registration between details of the virtual surgical plan and the real anatomy of interest. The registration enables a surgeon to implement the virtual surgical plan on the real anatomy of interest without the use of tracking markers.

    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.
