Implant planning using corrected captured joint motion information
First Claim
1. A surgical system, comprising:
- a tracking system;
an input device;
a display device; and
a computing system configured to;
capture, using the tracking system, corrected bone pose data for a native joint of a patient at a plurality of poses within a range of motion of the joint, wherein a corrective force is applied to the joint while the data is captured;
associate the corrected bone pose data with a representation of the joint;
receive, using the input device, an input from a user comprising a proposed pose of an implant component relative to the joint;
associate a representation of the implant component with a representation of a first bone in the representation of the joint in the proposed pose;
evaluate the proposed pose using the corrected bone pose data, wherein evaluating the proposed pose comprises determining a distance from a first point on a surface of the representation of the implant component to a second point, wherein the second point is one of;
(1) a point on a surface of a representation of a second bone of the joint or (2) a point on a surface of a representation of a second implant component associated with the representation of the second bone; and
display the evaluation to the user on the display device.

Abstract
The description relates to surgical computer systems, including computer program products, and methods for implant planning using corrected captured joint motion information. Data representative of a corrected limb pose at a plurality of poses within a range of motion of a joint associated with a particular individual is captured, the joint comprising a first bone and a second bone, while the first bone, the second bone, or both are subject to a corrective force aligning the first and second bones in a desired alignment. The first bone of the joint is represented. The second bone of the joint is represented. A first implant model is associated with the representation of the first bone. A second implant model is associated with the representation of the second bone. Based on the captured data, a relationship is determined between the first implant model and the second implant model at one or more poses of the plurality of poses within the range of motion of the joint. Information representative of the determined relationship is displayed.

7. A surgical method, comprising:
-
capturing, using a tracking system associated with a computing system, corrected bone pose data for a native joint of a patient at a plurality of poses within a range of motion of the joint, wherein a corrective force is applied to the joint while the data is captured; associating, by the computing system, the corrected bone pose data with a representation of the joint; receiving, at an input device associated with the computing system, an input from a user comprising a proposed pose of an implant component relative to the joint; associating, by the computing system, a representation of the implant component with a representation of a first bone in the representation of the joint in the proposed pose; evaluating, by the computing system, the proposed pose using the corrected bone pose data, wherein evaluating the proposed pose comprises determining a distance from a first point on a surface of the representation of the implant component to a second point, wherein the second point is one of;
(1) a point on a surface of a representation of a second bone of the joint or (2) a point on a surface of a representation of a second implant component associated with the representation of the second bone; anddisplaying the evaluation to the user on a display device. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18)
