Implant planning using captured joint motion information
First Claim
1. A surgical planning method comprising:
- capturing data as a native joint is moved within a range of motion of the joint using a tracking system associated with a computing system, the joint comprising a first bone and a second bone;
using the computing system to perform the steps of;
representing the first bone of the joint;
associating a first implant model with the representation of the first bone;
representing a second bone of the joint;
based on the captured data, determining, at a plurality of flexion angles within the range of motion of the joint, a distance from at least one point on a surface of the first implant model to at least one of;
(1) at least one point on a surface of the representation of the second bone or (2) at least one point on a surface of a second implant model associated with the representation of the second bone; and
displaying information representative of the determined distances at the plurality of flexion angles in a graphical representation indicating at least one of the plurality of flexion angles and the determined distance for the at least one of the plurality of flexion angles.

Abstract
The description relates to surgical computer systems, including computer program products, and methods for implant planning using captured joint motion information. Data is captured representative of a range of motion of a joint associated with a particular individual, where the joint includes a first bone and a second bone. The first bone of the joint is represented and a first implant model is associated with the representation of the first bone. Based on the captured data, a relationship is determined between the first implant model and a representation of the second bone or a second implant model through at least a portion of the range of motion of the joint. Information is displayed representative of the determined relationship.
