Abstract

A surgical procedure is provided. The procedure acquires a plurality of points on or near a bone abnormality and registers them with a surgical navigation system. The navigation system uses the acquired points to make an implant having a surface adapted to contact the bone, and particularly an implant having a portion whose shape substantially matches that of the bone abnormality.

Claims

1. A method of performing a surgical procedure, comprising:

providing a tracking system and a diagnostic scope that is tracked by the tracking system;

identifying an abnormality on a bone with the diagnostic scope;

acquiring a plurality of points on or near the abnormality with the diagnostic scope; and

using the acquired points to make an implant having a portion whose shape substantially matches that of the bone abnormality.

2. The method of claim 1, wherein the acquisition of the plurality of points on or near the abnormality with the diagnostic scope comprises collecting and analyzing dimensional data of the abnormality.

3. The method of claim 2, wherein the making of the implant having a portion whose shape substantially matches that of the bone abnormality comprises custom manufacturing the implant based on the collected and analyzed dimensional data of the abnormality.

4. The method of claim 1, wherein the making of the implant having a portion whose shape substantially matches that of the bone abnormality comprises accessing a computer database containing one or more reference implant models.

5. The method of claim 1, further comprising generating a representative model of the bone abnormality from the acquired points.

6. The method of claim 5, wherein the representative model of the bone abnormality comprises a three-dimensional and manipulatable image of the bone abnormality, the image showing the acquired points.

7. The method of claim 1, further comprising inserting a fiducial marker into the bone at or near the abnormality so that images taken in a first procedure can be registered with images taken in a later procedure.

8. The method of claim 1, further comprising installing the implant onto the bone.

9. The method of claim 8, wherein the implant is installed onto the bone by using the tracking system.

10. The method of claim 1, wherein the acquisition of the plurality of points on or near the abnormality with the diagnostic scope comprises registering each point with the tracking system by using an inputting means selected from at least one of a selective gesturing technique, a virtual mouse technique and a button activation technique.

11. The method of claim 1, wherein the bone abnormality is on a femur.

12. The method of claim 1, wherein the bone abnormality is on a tibia.

13. An image guided surgery system, comprising:

a computer having surgical navigation utilities software;

a tracking system having a measurement field; and

a diagnostic scope trackable by the tracking system when exposed to the measurement field;

wherein the surgical navigation utilities software comprises a program that when executed causes the system to acquire a plurality of points on or near the abnormality to make an implant having a portion whose shape substantially matches that of the bone abnormality.

14. The system of claim 13, wherein the acquisition of the plurality of points on or near the abnormality with the diagnostic scope comprises the system collecting and analyzing dimensional data of the abnormality.

15. The system of claim 14, wherein the making of the implant having a portion whose shape substantially matches that of the bone abnormality comprises the system producing information for custom manufacturing the implant based on the collected and analyzed dimensional data of the abnormality.

16. The system of claim 13, wherein the making of the implant having a portion whose shape substantially matches that of the bone abnormality comprises the system accessing a computer database containing one or more reference implant models.

17. The system of claim 13, wherein the software program further causes the system to generate a representative model of the bone abnormality from the acquired points.

18. The system of claim 17, wherein the representative model of the bone abnormality comprises a three-dimensional and manipulatable image of the bone abnormality, the image showing the acquired points.

19. The system of claim 13, further comprising a fiducial marker insertable into the bone at or near the abnormality so that images taken in a first procedure can be overlaid on images taken in a later procedure.

20. The system of claim 13, wherein the implant is adapted to be installed onto the bone by mating the implant with the bone abnormality.

21. The system of claim 20, wherein the implant is adapted to be installed onto the bone by using the tracking system.

22. The system of claim 13, wherein the acquisition of the plurality of points on or near the abnormality comprises the diagnostic scope registering each point with the tracking system by using an inputting means selected from at least one of a selective gesturing technique, a virtual mouse technique and a button activation technique.

23. A computer readable storage medium storing instructions that, when executed by a computer, cause the computer to perform the computer-implemented steps of:

tracking a diagnostic scope with a tracking system when the diagnostic scope is exposed to a measurement field of the tracking system;

acquiring a plurality of points on or near a bone abnormality as the diagnostic scope is tracked; and

defining dimensional parameters of the abnormality based upon the plurality of points acquired.

24. The computer readable storage medium of claim 23, wherein the computer-implemented steps further comprise generating a model of the bone abnormality from the plurality of points acquired.

25. The computer readable storage medium of claim 24, wherein the model of the bone abnormality comprises a three-dimensional and manipulatable image of the bone abnormality, the image showing the acquired points.

26. The computer readable storage medium of claim 23, wherein the computer-implemented steps further comprise generating a model of an implant having a portion whose shape substantially matches that of the bone abnormality, whereby an implant to correct the abnormality can be manufactured from the model.

27. The computer readable storage medium of claim 23, wherein the computer-implemented steps further comprise generating a virtual image of one or more implants that can be used to correct the abnormality.
