Abstract: This disclosure describes a surgical implant device comprising a body that includes a porous material forming at least a portion of the body, wherein the porous material is configured to promote bone ingrowth and is porous to a fluid. In addition, one or more fluid channels are formed in the body. The one or more fluid channels are arranged to define a fluidic path that exits into the porous material.

Abstract: A method comprises determining, by a surgical assistance system, a potential insertion point on a surface of a bone of a patient; and presenting, by a Mixed Reality (MR) visualization device of the surgical assistance system, an MR scene that includes a virtual trajectory guide, wherein: the virtual trajectory guide comprises an elliptical surface, and for each location of a plurality of locations on the elliptical surface: the location corresponds to a potential insertion axis that passes through the location and the potential insertion point on the surface of the bone, and the location is visually distinguished based on a quality of a portion of the bone along the potential insertion axis corresponding to the location.

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: 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 are described for bone-graft harvesting in orthopedic surgery. Processing circuitry may obtain a virtual model of a bone graft to be harvested from a donor bone, wherein the virtual model of the bone graft specifies a volume of the donor bone to be harvested as the bone graft; and output for display, via a visualization device, a graphical representation of the specified volume to be harvested relative to a portion of the donor bone viewable via the visualization device.

Abstract: An example system for designing a patient matched implant for an orthopedic joint repair surgical procedure includes a memory configured to store a model of a bone of a patient; and processing circuitry. The processing circuitry may be configured to: obtain the model of the bone of the patient; obtain a template model of an implant; determine a shape of a surface of the implant; determine a volume between the shape of the surface of the implant and a surface of the bone defined by the model of the bone; generate, based on the determined volume and the template model, a patient matched implant model; and output a file representing the patient matched implant model.

In addition, one or more fluid channels are formed in the body. The one or more fluid channels are arranged to define a fluidic path that exits into the porous material.

Abstract: A computing system obtains motion data describing a movement of an appendage of a patient. Additionally, the computing system determine, based on the motion data, a range of motion of the appendage. Furthermore, the computing system generates, for display by an extended reality visualization device, an extended reality visualization of the range of motion of the appendage superimposed on an image of the patient or an avatar of the patient.
