Implant planning using captured joint motion information

摘要

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 through at least a portion of the range of motion of the joint. Information is displayed representative of the determined relationship.

1. A surgical planning method comprising:
capturing data, using a tracking system associated with a computing system as a native joint is moved within, a range of motion of a joint the joint comprising a first bone and a second bone; wherein the computing system is further used 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; associating a second implant model with the representation of the second bone; based on the captured data, determining a distance from at least one point on a surface of the first implant model to at least one point on a surface of the second implant model at a plurality of angles within the range of motion of the joint, and displaying information representative of the respective determined distances at the plurality of angles, wherein the information representative of the respective determined distances at the plurality of angles is displayed in the form of a bar chart indicating at least one of the plurality of angles and the respective determined distance for the at least one of the plurality of angles.
