Abstract

Certain embodiments provide systems and methods for intraoperative implant measurement. Certain embodiments of a method include noting a location of a first implant, noting a location of a second implant, measuring a distance between the first and second implants based on the location of the first implant and the location of the second implant, and displaying the distance to a user. Certain embodiments of a system include a processor configured to determine a distance between a first implant and a second implant based on tracking information for a location of the first implant and a location of the second implant and a display configured to display an image including the first and second implants and the distance to a user.

Claims

1. A method for intraoperative implant measurement, said method comprising:

noting a location of a first implant;

noting a location of a second implant;

measuring a distance between said first and second implants based on said location of said first implant and said location of said second implant; and

displaying said distance to a user.

2. The method of claim 1, further comprising noting a location of a third implant.

3. The method of claim 2, further comprising fitting said locations of said first, second and third implants to a curve.

4. The method of claim 1, further comprising suggesting a connecting rod length based on said distance.

5. The method of claim 1, further comprising suggesting a curvature of a connecting rod based on said distance.

6. The method of claim 1, further comprising highlighting said distance on an image display.

7. The method of claim 1, further comprising recommending an interconnection component characteristic based on said distance.

8. The method of claim 1, further comprising storing implant placement and distance measurement information for subsequent implant placement.

9. The method of claim 1, wherein said first and second implants are graphically rendered and overlaid on an image with trajectory information and distance information.

10. A user interface system for intraoperative implant measurement, said system comprising:

a processor configured to determine a distance between a first implant and a second implant based on tracking information for a location of said first implant and a location of said second implant; and

a display configured to display an image including said first and second implants and said distance to a user.

11. The system of claim 10, wherein said display highlights said distance on said image.

12. The system of claim 10, wherein said processor recommends an interconnection component characteristic based on said distance.

13. The system of claim 12, wherein said interconnection component characteristic comprises at least one of component length and component curvature.

14. The system of claim 10, wherein said processor stores implant placement and distance measurement information for subsequent implant placement.

15. The system of claim 10, wherein said display graphically renders said first and second implants and overlays said first and second on said image with trajectory and distance measurement information.

16. The system of claim 10, wherein said processor receives tracking information for a plurality of implants and fits locations of said plurality of implants to a curve.

17. The system of claim 10, wherein said tracking information includes position and orientation information for said first implant and said second implant.

18. A computer-readable medium having a set of instructions for execution on a computer, said set of instructions comprising:

a tracking routine for noting locations of a plurality of implants;

a distance measurement routine for determining a distance between said plurality of implants based on said locations of said plurality of implants; and

a display routine for indicating said distance to a user.

19. The set of instructions of claim 18, wherein said display routine graphically renders said plurality of implants and overlays said plurality of implants on an image with said distance.

20. The set of instructions of claim 18, wherein said distance measurement routine receives tracking information for said plurality of implants and fits locations of said plurality of implants to a curve.

21. The set of instructions of claim 18, wherein said distance measurement routine recommends an interconnection component characteristic between said plurality of implants based on said distance.

22. The set of instructions of claim 18, wherein said locations include position and orientation for said plurality of implants.
