Surgical alignment using references
First Claim
1. A system, comprising:
- a guide having an outer contour adapted to substantially conform to a receiving portion of a joint, wherein the outer contour that is adapted to substantially conform to the receiving portion of the joint is formed prior to use of the guide, and the guide is adapted to mate with the receiving portion of the joint in a single orientation;
a first reference device for attachment to a bone of the joint;
a second reference device for coupling at a known alignment relative to the guide; and
a control unit configured to communicate with the first reference device and the second reference device, the control unit being configured to determine the position of the axis relative to the first reference device based on data that indicates a position of the second reference device relative to the first reference device when the second reference device is in the known alignment relative to the guide and the guide is mated to the joint.

Abstract
Methods, systems, and apparatus, including computer-readable storage media, for surgical alignment using references. In one general aspect, a method includes coupling a guide to a joint, the guide defining an axis and having an outer contour formed to substantially conform to a portion of the joint. The first reference is attached at a fixed position relative to the joint. A positioning system is used to determine a position of the axis relative to the first reference, where the position of the axis is determined based upon the position of the guide while the guide is coupled to the joint. The guide is removed from the joint, and after the guide is removed from the joint, an instrument is positioned relative to the axis based on a position of a second reference relative to the first reference.

10. A system, comprising:
-
a guide having an outer contour adapted to substantially conform to a receiving portion of a joint, the guide defining an axis that has a known position relative to the joint when the guide is mated to the joint, wherein the outer contour that is adapted to substantially conform to the receiving portion of the joint is formed prior to use of the guide, and the guide is adapted to mate with the receiving portion of the joint in a single orientation; a first reference device for attachment to a bone of the joint; a second reference device for coupling at a known alignment relative to the guide; and a control unit configured to communicate with the first reference device and the second reference device, the control unit being configured to determine the position of the axis relative to the first reference device based on data that indicates a position of the second reference device relative to the first reference device when the second reference device is in the known alignment relative to the guide and the guide is mated to the joint. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
