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.
Claims19
A system for guiding bone graft harvesting, the system comprising:
- a visualization device;
- and
- processing circuitry configured to:
- 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, wherein the donor bone is a bone cap;
- and
- after resection of a humeral head of a patient to produce the bone cap:
- identify, via the visualization device, the bone cap;
- and
- output for display, via the visualization device, the virtual model of the bone graft overtop of or inside the bone cap while the bone cap is viewable via the visualization device.
A method for bone graft harvesting in orthopedic surgery, the method comprising:
- obtaining, by processing circuitry of a visualization device, 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, wherein the donor bone is a bone cap;
- and
- after resection of a humeral head of a patient to produce the bone cap:
- identifying, by the visualization device, the bone cap;
- and
- outputting for display, via the visualization device, the virtual model of the bone graft overtop of or inside the bone cap while the bone cap is viewable via the visualization device.
A system for bone graft selection in orthopedic surgery, the system comprising:
- means for obtaining 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, wherein the donor bone is a bone cap;
- and
- after resection of a humeral head of a patient to produce the bone cap:
- means for identifying the bone cap;
- and
- means for outputting for display the virtual model of the bone graft overtop of or inside the bone cap while the bone cap is viewable via a visualization device.
A non-transitory computer-readable storage medium storing instructions that when executed cause one or more processors to:
- 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, wherein the donor bone is a bone cap;
- after resection of a humeral head of a patient to produce the bone cap:
- identify, via a visualization device, the bone cap;
- and
- output for display, via the visualization device, the virtual model of the bone graft overtop of or inside the bone cap while the bone cap is viewable via the visualization device.
