US 11,376,072 B2 · Implant planning for multiple implant components using constraints

Abstract

Described are computer-based methods and apparatuses, including computer program products, for implant planning for multiple implant components using constraints. A representation of a bone and a representation of a first implant component are displayed with respect to the representation of the bone. A representation of a second implant component is displayed, wherein the first implant component and the second implant component are physically separated and not connected to each other. A positioning of the representation of the second implant component that violates at least one positioning constraint is prevented, wherein the positioning constraint is based on the representation of the first implant component.

Claims21

Dependent claims

A surgical planning computerized method, comprising:

registering a joint of a patient in physical space with a model of the joint in virtual space;
planning placement of an implant to be implanted in the joint, wherein a planned placement of the implant is determined by:
performing a soft tissue assessment of the joint;
and
automatically fitting the implant relative to at least one of a bone of the joint, a second implant, a cartilage of the patient, or based on a ligament characteristic of the patient;
and
generating at least one virtual boundary based on the planned placement of the implant in the joint, the at least one virtual boundary configured to control movement of a surgical tool while the tool is being used to prepare the joint to receive the implant in the planned placement.
