Patient-matched surgical component and methods of use
First Claim
1. A method of automatically registering a surgical navigation system to a patient'"'"'s anatomy, comprising:
- using the surgical navigation system to pre-register a first spatial relationship between a surgical component and a reference array connected to the surgical component;
using the surgical navigation system to pre-register a second spatial relationship between an anatomical feature of a patient and the surgical component;
installing the surgical component on the patient such that the surgical component engages the anatomical feature in the second spatial relationship; and
locating the reference array with the surgical navigation system to automatically register the position of the reference array relative to the patient'"'"'s anatomy wherein the navigation system automatically registers the position of the reference array relative to the patient'"'"'s anatomy when the reference array is within a measurement field of the navigation system.

Abstract
A patient matched surgical component including a body having a surface that is preoperatively shaped to substantially mate with the shape of an anatomical feature of a patient in a predefined spatial relationship, the surface being shaped by preoperatively identifying a finite number of bony anatomical landmarks on a representative model of the anatomical feature, and a reference array preoperatively integrated with a surgical navigation tracking system in a predefined spatial orientation relative to the anatomical feature, the reference array being couplable to the body such that when the surgical component is installed onto the anatomical feature intraoperatively, the position of the anatomical feature relative to the reference array is automatically recognized by the surgical navigation system.

12. A method of performing a surgical procedure aided by a surgical navigation system, comprising:
-
generating a representative model of an anatomical feature from an image of a patient'"'"'s anatomy; using the model to make a surgical component, the surgical component having a surface that is shaped to substantially mate with the anatomical feature in a predefined spatial relationship; installing the surgical component on the anatomical feature by mating the surface of the component with the anatomical feature in the predefined spatial relationship; and tracking movement of the anatomical feature with a tracking system when the installed surgical component is moved within a measurement field of the tracking system by tracking movement of the surgical component within the measurement field of the tracking system. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A method of performing a surgical procedure aided by a surgical navigation system, comprising:
-
generating a representative model of an anatomical feature from an image of a patient'"'"'s anatomy; using the model to make a surgical component, the surgical component having a reference array associated therewith and a surface that is shaped to substantially mate with an anatomical feature in a predefined spatial relationship; installing the surgical component on the anatomical feature by mating the surface of the component with the anatomical feature in the predefined spatial relationship; tracking movement of the anatomical feature with the tracking system when the installed surgical component is moved within a measurement field of the tracking system; removing a portion of the anatomical feature, the removed portion also including a portion of the installed surgical component; and tracking a remaining portion of the anatomical feature with the tracking system, the remaining portion of the anatomical feature including a portion of the installed surgical component, the remaining portion of the installed surgical component including the reference array. - View Dependent Claims (20, 21, 22, 23, 24)
