Abstract
A method of automatically registering a surgical navigation system to a patient's anatomy is provided. The method comprises programming a surgical navigation system with a first spatial relationship between a surgical component and a reference array connected to the surgical component, programming the surgical navigation system with 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. The navigation system automatically recognizes the position of the reference array relative to the patient's anatomy.

A method of automatically registering a surgical navigation system to a patient's anatomy, comprising:
- programming the surgical navigation system with a first spatial relationship between a surgical component and a reference array connected to the surgical component;
- programming the surgical navigation system with 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, wherein the navigation system automatically recognizes the position of the reference array relative to the patient's anatomy.
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.
A patient matched surgical component, comprising:
- a body having a surface that is shaped to substantially mate with the shape of an anatomical feature of a patient in a predefined spatial relationship;
- and
- a reference array connected to the body, the reference array being trackable by a tracking system when exposed to a measurement field of the tracking system.
