displaying a virtual drilling axis having parameters obtained from the virtual surgical plan, the virtual drilling axis configured to guide attachment of a guide pin to a humerus of the patient, wherein the guide pin is configured to guide attachment of a resection guide to the humerus, wherein the guide pin is attached to a humeral head of the humerus that is removed as a result of performance of a resection of the humeral head of the humerus using the resection guide, and wherein the virtual drilling axis is not parallel to a cutting plane of the resection guide.
2. The method of claim 1 , further comprising:
displaying, via the visualization device, virtual guidance configured to guide adjustment of the resection guide.
3. The method of claim 2 , wherein displaying the virtual guidance configured to guide adjustment of the resection guide comprises displaying a virtual cutting plane at a desired location of the cutting plane of the resection guide.
4. The method of claim 2 , wherein displaying the virtual guidance configured to guide adjustment of the resection guide comprises displaying guidance to which screws of the resection guide are to be tightened or loosened.
5. The method of claim 1 , wherein the orthopedic joint repair surgical procedure is one of a standard total shoulder arthroplasty or a reverse shoulder arthroplasty.
6. The method of claim 1 , wherein displaying the virtual guide comprises projecting the virtual guide via a see-through lens through which a user is able to view the anatomy of the patient.
7. The method of claim 6 , wherein the portion of the anatomy of the patient is viewable via one or more see-through lenses of the visualization device, the method further comprising displaying the virtual model and displaying the virtual guide via the see-through lenses.
8. The method of claim 1 , wherein displaying the virtual guide comprises:
displaying a virtual reaming axis having parameters obtained from the virtual surgical plan, the virtual reaming axis configured to guide attachment of a second guide pin to the humerus, wherein the second guide pin is configured to guide reaming of a graft in the humeral head of the humerus of the patient.
9. The method of claim 1 , wherein displaying the virtual guide comprises:
displaying a virtual cutting plane having parameters obtained from the virtual surgical plan, the virtual cutting plane configured to guide cutting of a graft from the humeral head of the humerus of the patient.
10. The method of claim 1 , wherein displaying the virtual guide comprises:
displaying a virtual reaming axis having parameters obtained from the virtual surgical plan, the virtual reaming axis configured to guide reaming of a graft in the humeral head of the humerus of the patient.
11. The method of claim 1 , wherein displaying the virtual guide comprises:
displaying a virtual reaming axis having parameters obtained from the virtual surgical plan, the virtual reaming axis configured to guide reaming of the humeral head of the humerus of the patient.
12. The method of claim 1 , wherein displaying the virtual guide comprises:
displaying virtual guidance to guide one or more of: sounding the humerus, punching the humerus, or compacting the humerus.
13. The method of claim 1 , wherein displaying the virtual guide comprises:
displaying a virtual axis having parameters obtained from the virtual surgical plan, the virtual axis configured to guide creation of a pilot hole in the humerus of the patient after the humeral head has been resected.
14. The method of claim 1 , wherein, when installed, a tip of the guide pin is shallower in the humeral head than the cutting plane of the resection guide.
15. A mixed reality system comprising:
a memory that stores at least a portion of a virtual surgical plan;
a visualization device; and
one or more processors configured to:
display, via the 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
display, 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, wherein, to display the virtual guide, the one or more processors are configured to display a virtual drilling axis having parameters obtained from the virtual surgical plan, the virtual drilling axis configured to guide attachment of a guide pin to a humerus of the patient, wherein the guide pin is configured to guide attachment of a resection guide to the humerus, wherein the guide pin is attached to a humeral head of the humerus that is removed as a result of performance of a resection of the humeral head of the humerus using the resection guide, and wherein the virtual drilling axis is not parallel to a cutting plane of the resection guide.
16. The mixed reality system of claim 15 , wherein the one or more processors are further configured to:
display, via the visualization device, virtual guidance configured to guide adjustment of the resection guide.
17. The mixed reality system of claim 16 , wherein, to display the virtual guidance configured to guide adjustment of the resection guide, the one or more processors are configured to display a virtual cutting plane at a desired location of the cutting plane of the resection guide.
18. The mixed reality system of claim 16 , wherein, to display the virtual guidance configured to guide adjustment of the resection guide, the one or more processors are configured to display guidance to which screws of the resection guide are to be tightened or loosened.
19. The mixed reality system of claim 15 , wherein, to display the virtual guide, the one or more processors are configured to:
display a virtual axis having parameters obtained from the virtual surgical plan, the virtual axis configured to guide creation of a pilot hole in the humerus of the patient after the humeral head has been resected.
20. A non-transitory computer-readable storage medium storing instructions that, when executed, cause one or more processors of a mixed reality system to:
display, 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
display, 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, wherein the instructions that cause the one or more processors to display the virtual guide comprise instructions that cause the one or more processors to display a virtual drilling axis having parameters obtained from the virtual surgical plan, the virtual drilling axis configured to guide attachment of a guide pin to a humerus of the patient, wherein the guide pin is configured to guide attachment of a resection guide to the humerus, wherein the guide pin is attached to a humeral head of the humerus that is removed as a result of performance of a resection of the humeral head of the humerus using the resection guide, and wherein the virtual drilling axis is not parallel to a cutting plane of the resection guide.
