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.

An example system includes a first device configured to display a first presentation to a first user, wherein the first presentation includes one or more virtual elements configured to assist the first user in an orthopedic surgical procedure; and a second device configured to display a second presentation to a second user, wherein the second user provides surgical assistance on the orthopedic surgical procedure. In this example, the second device is further configured to display content that informs the second user on one or more previously-executed steps of the orthopedic surgical procedure.

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.

Modular humeral implants and methods of use. A humeral implant can include a stem portion, a metaphyseal portion, a locking element, and an intermediate portion. The intermediate portion can include at least one spacer. Each spacer can include a proximal engagement feature, a distal engagement feature, a lumen extending longitudinally through the spacer, and a pin slidable within the lumen of the spacer. Distal movement of a locking element in the metaphyseal portion can translate the pin of each spacer to secure the metaphyseal portion, the intermediate portion, and the stem portion in a locked configuration.

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.

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.

An improved modular rotational device includes a first and second threaded coupler for affixation along the stem of an endoprosthetic device, for example, a humeral prosthesis or a femoral prosthesis. The rotational device axis of rotation is coaxial with the stem, and its axis of rotation is located in close proximity to the intramedullary stem of the prosthesis or in close proximity to the distal articulation of the prosthesis. A housing has a proximal and distal end with an axial bore therethrough for receiving an elongated stem of the device. A lobe ring may be utilized to limit the axis of rotation of the device. Additional endoprosthetic devices may be attached to male or female threaded couplers, or to Morse tapers. A plurality of suture attachments facilitates attachment of soft tissue thereto.

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.

The present disclosure generally relates to a surgical tool for use in shoulder arthroplasty. The surgical tool includes a humeral head cut guide configured to fit within a rotator interval of a subject in need of shoulder arthroplasty. The cut guide can further include a top surface, a bottom surface, a front surface, a back surface, and at least two sides. The surgical tool can also have at least two nonconverging pin holes and a receiving portion configured to permit reversible attachment of the cut guide to an attachment arm assembly.

A method and apparatus for coupling soft tissue to a prosthetic is disclosed. Soft tissue attachment pads having porous metal attachment regions and suture accepting holes are selectively positioned onto an implantable prosthetic to provide coupling locations.
