Abstract

A method for pre-operative orthopedic planning includes obtaining only a high-resolution knee-joint scan of a patient, determining hip rotation center and ankle rotation center from anthropometric data based on personal data of the patient, and determining a mechanical axis of the knee joint based on the anthropometric data. The method also includes preparing at least a two-dimensional image model of the knee joint using the knee-joint scan and the determined mechanical axis, and preparing a pre-operative surgical plan based on the image of the knee joint.

Claims (34)

1. A method for pre-operative orthopedic planning comprising:

creating a diseased bone database;

obtaining image-free personal data of a patient including age, gender, weight and height of the patient;

selecting a best-fit bone model from the diseased bone database based on the obtained image-free personal data of the patient;

transforming the best-fit bone model to a customized bone model matching the obtained image-free personal data of the patient using morphing software;

preparing a pre-operative surgical plan based on the customized bone model without obtaining image data of the patient; and

physically manufacturing a customized physical alignment guide based on the customized bone model.

2. The method of claim 1 , wherein transforming the best-fit bone model to a customized bone model matching the personal data of the patient includes transforming the best-fit bone model to match a hip height of the patient.

3. The method of claim 1 , wherein transforming the best-fit bone model to a bone model matching the personal data of the patient includes transforming the best-fit bone model to match a tibial height of the patient.

4. The method of claim 1 , wherein transforming the best-fit bone model to a bone model matching the personal data of the patient includes transforming the best-fit bone model to match a hip angle of the patient.

5. The method of claim 1 , wherein transforming the best-fit bone model to a bone model matching the personal data of the patient includes transforming the best-fit bone model to match a tibial angle of the patient.

6. The method of claim 1 , wherein preparing a pre-operative surgical plan further comprises selecting an implant for the patient.

7. The method of claim 6 , wherein the implant is selected from a customized or semi-customized or non-customized implant based on the customized bone model.

8. The method of claim 1 , further comprising selecting a best-fit bone model from the diseased bone database including daily activity of the patient.

9. The method of claim 1 , further comprising selecting a best-fit bone model from the diseased bone database including body mass index of the patient.

10. The method of claim 1 , wherein the diseased bone database includes images and measurement of diseased and deformed bones and bone joints.

11. A method for pre-operative orthopedic planning comprising:

creating a diseased bone database;

obtaining image-free personal data of a patient including one or more of age, gender, disability, race, ethnicity and weight of the patient;

selecting a best-fit bone model from the diseased bone database based on the personal data of the patient;

transforming the best-fit bone model to a customized bone model by matching at least one of hip height, tibial height, hip angle and tibial angle of the patient using morphing software;

preparing a pre-operative surgical plan based on the customized bone model without obtaining image data of the patient; and

manufacturing a physical customized alignment guide based on the customized bone model.

12. The method of claim 11 , wherein preparing a pre-operative surgical plan further comprises selecting an implant for the patient.

13. The method of claim 12 , wherein the implant is selected from a customized or semi-customized or non-customized implant based on the customized bone model.

14. The method of claim 11 , further comprising selecting a best-fit bone model from the diseased bone database including daily activity of the patient.

15. The method of claim 11 , further comprising selecting a best-fit bone model from the diseased bone database including body mass index of the patient.

16. A method for pre-operative orthopedic planning comprising:

obtaining image-free personal data of a patient including one or more of age, gender, disability, race, ethnicity and weight;

selecting a best-fit bone model from a diseased bone database based on the personal data of the patient;

transforming the best-fit model to a customized bone model matching at least one of hip height, tibial height, hip angle and tibial angle of the patient using morphing software;

preparing a pre-operative surgical plan based on the customized bone model without obtaining image data of the patient; and

manufacturing a physical customized alignment guide based on the customized bone model to achieve the prepared pre-operative surgical plan.

17. The method of claim 16 , further comprising creating a diseased bone database including images and measurement of diseased and deformed bones and bone joints.
