Bone milling with image guided surgery
First Claim
1. A method of resurfacing a bone at a surgical site during a surgical navigation procedure, comprising:
- providing a tracking system and a surgical instrument having a tracking array, the tracking array being identified and tracked by the tracking system;
moving the surgical instrument relative to the bone while the tracking system tracks the position of the surgical instrument, the relative movement being projected on an image of the bone;
viewing the projected image as the surgical instrument is moved relative to the bone to determine when the surgical instrument is positioned at the surgical site;
using the surgical instrument to make a hole in the bone at the surgical site; and
inserting a guide pin into the hole.

Abstract
A method for resurfacing a bone at a surgical site during a surgical navigation procedure is provided. The method comprises providing a tracking system and a surgical instrument having a tracking array, the tracking array being identified and tracked by the tracking system. The surgical instrument is moved relative to a bone while the tracking system tracks the position of the surgical instrument, and the relative movement is projected on an image of the bone. The projected image is viewed as the surgical instrument is moved relative to the bone to determine when the surgical instrument is positioned at the surgical site. The surgical instrument is used to make a hole in the bone at the surgical site, and a guide pin is inserted into the hole.

13. A method of performing a knee procedure using surgical navigation, comprising:
-
providing a tracking system and a surgical instrument having a tracking array, the tracking array being identified and tracked by the tracking system;
using the tracking system to guide the surgical instrument to a surgical site on a patient'"'"'s femur;
using a surgical tool to create a first substantially planar surface on a condyle of the patient'"'"'s femur at the surgical site; and
installing a surgical implant on the femur;
wherein the procedure is performed without a referencing guide. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)

25. A computer readable storage medium for use with a surgical navigation system, the storage medium storing instructions that, when executed during a bone resurfacing procedure, cause the surgical navigation system to implement the following steps:
-
tracking a surgical instrument having a tracking array with a tracking system as the surgical instrument moves relative to the bone;
projecting the relative movement of the surgical instrument on an image of the bone;
displaying a mechanical axis on the image, the mechanical axis being positioned relative to the surgical site;
identifying a location on the image having a corresponding location on the bone for inserting a guide pin once the surgical instrument is positioned at the surgical site; and
generating instructions for creating a first substantially planar surface on a first portion of the bone at the location of the first guide pin. - View Dependent Claims (26, 27, 28, 29, 30)
