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.

Soft tissue structure determination from CT images

Orthopedic surgical planning based on soft tissue and bone density modeling

An example method includes displaying, via a visualization device and overlaid on a portion of an anatomy of a patient viewable via the visualization device, a virtual model of the portion of the anatomy obtained from a virtual surgical plan for an orthopedic joint repair surgical procedure to attach a prosthetic to the anatomy; and displaying, via the visualization device and overlaid on the portion of the anatomy, a virtual guide that guides at least one of preparation of the anatomy for attachment of the prosthetic or attachment of the prosthetic to the anatomy.

Virtual guidance for orthopedic surgical procedures

A computing system generates, based on medical imaging data of bones of a joint of a patient, bony landmark data that characterizes relationships between two or more landmarks on one or more of the bones of the joint of the patient. Additionally, the computing system applies a classifier algorithm that has been trained using training data to select a class associated with the patient from among a plurality of classes. The classifier algorithm takes the bony landmark data of the patient as input.

Use of bony landmarks in computerized orthopedic surgical planning

An example device includes a surgical item for use in a surgical procedure; and a light on or within the surgical item. In this example, the light is controllable by an external device so as to identify the surgical item for use in the surgical procedure.

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.

Automated planning of shoulder stability enhancement surgeries

Techniques are described for determining a pre-morbid shape of an anatomical object. Processing circuitry may determine an aligned shape based on image data with under- or over-segmentation. The processing circuitry may utilize the aligned shape and a shape model such as a mean shape model of the anatomical object to register the aligned shape to the shape model and generate information indicative of the pre-morbid shape of the anatomical object.

Pre-morbid characterization of anatomical object using statistical shape modeling (SSM)

An example medical device system includes a plurality of surgical items; and a visualization device configured to present a mixed reality (MR) presentation to a user; and one or more processors configured to select a surgical item of the plurality of surgical items based on a surgical procedure and present, in the MR presentation, virtual information that identifies the selected surgical item among the plurality of surgical items, wherein the virtual information is presented on or adjacent a position of the selected surgical item visible via the visualization device.

Automated instrument or component assistance using mixed reality in orthopedic surgical procedures

An example mixed reality (MR) system includes a first MR device configured to present first medical information and first real-world information to a first user via a first MR presentation; a second MR device configured to provide second medical information and second real-world information to a second user via a second MR presentation; and a third device configured to provide third information to a third user, wherein the third information is based at least in part on the first MR presentation or the second MR presentation.

Multi-user collaboration and workflow techniques for orthopedic surgical procedures using mixed reality

An extended reality (XR) visualization device worn by an orthopedic surgeon outputs a XR visualization for display. The XR visualization includes a set of one or more virtual checklist items. Each of the one or more virtual checklist items corresponds to an item in a checklist of steps of an orthopedic surgery. Additionally, the XR visualization device detects a command of the orthopedic surgeon to select a virtual checklist item in the set of virtual checklist items. In response to detecting the command, the XR visualization device updates the XR visualization to include additional information regarding a step of the orthopedic surgery corresponding to the selected virtual checklist item.

Virtual checklists for orthopedic surgery

A computing system generates a plurality of training datasets from past shoulder surgery cases and uses the plurality of training datasets to train a neural network. Each output layer neuron in a plurality of output layer neurons of the neural network corresponds to a different class in one or more shoulder pathology classification systems. The computing system may obtain a current input vector that corresponds to a current patient. Additionally, the computing system may apply the neural network to the current input vector to generate a current output vector. The computing system may determine, based on the current output vector, a recommended type of shoulder surgery for the current patient.

Neural network for recommendation of shoulder surgery type

An example system for demonstrating at least one aspect of an orthopedic surgical procedure includes a first device and a second device. In this example, the first device is configured to display a presentation to a first user, wherein the presentation includes one or more virtual elements and wherein the one or more virtual elements comprise a three-dimensional (3D) virtual representation of one or more anatomical features associated with the orthopedic surgical procedure. In this example, the second device is configured to display the presentation to a second user. In this example, the one or more virtual elements demonstrate at least one aspect of the orthopedic surgical procedure and wherein control of at least some of the one or more virtual elements are assignable from the first device to the second device.

Mixed reality-aided education using virtual models or virtual representations for orthopedic surgical procedures

An example system for demonstrating at least one aspect of an orthopedic surgical procedure includes a first device configured to display a presentation to a first user while the first user is wearing the device, wherein the presentation includes virtual element(s) that are controllable by the first user while the first user is wearing the first device, and wherein the virtual element(s) comprise a 3-dimensional (3D) virtual representation of one or more anatomical features associated with the orthopedic surgical procedure; and a second device configured to display the presentation to a second user, wherein the virtual element(s) further include virtual pre-operative plan element(s) shown relative to the 3D virtual representation, virtual surgical guidance feature(s) shown relative to the 3D virtual representation, or surgical result(s) virtually illustrated on the 3D virtual representation so as to demonstrate aspect(s) of the orthopedic surgical procedure.
