Abstract

In some embodiments, a synthetic (virtual) orthopedic treatment device (e.g. a virtual external fixator representing a physical fixator attachable to a patient anatomic structure) is displayed concurrently in two views (e.g. anterior-posterior and lateral) along corresponding digital medical images (e.g. X-rays), and rotation/translation user input received along one of the images is used to concurrently control both displays of the orthopedic treatment device to reflect the rotation/translation user input.

First claim

What is claimed is:

1. A computer system comprising at least one microprocessor configured to execute instructions to:
generate a first display of a graphical representation of a first fixation ring of an orthopedic treatment device superimposed on a representation of a first bone segment in a first view;
concurrently with generating the first display, generate a second display of the graphical representation of the first fixation ring of the orthopedic treatment device superimposed on the representation of the first bone segment in a second view at a different angle from the first view;
receive user input entered on the first display of the graphical representation of the first fixation ring of the orthopedic treatment device, the user input controlling a motion of the graphical representation of the first fixation ring of the orthopedic treatment device; and
in response to receiving the user input, update the first display of the graphical representation of the first fixation ring of the orthopedic treatment device and the second display of the graphical representation of the first fixation ring of the orthopedic treatment device to reflect the motion of the graphical representation of the first fixation ring of the synthetic orthopedic treatment device,
wherein the motion comprises at least one of a rotation motion and a translation motion.

2. The computer system of claim 1 , wherein the first view is an anterior-posterior (AP) view, and the second view is a lateral view.

3. The computer system of claim 1 , wherein the first view is a lateral view, and the second view is an anterior-posterior (AP) view.

4. The computer system of claim 1 , wherein the motion comprises the rotation motion and the translation motion.

5. The computer system of claim 1 , wherein the orthopedic treatment device is an external fixator comprising the first fixation ring and a second fixation ring interconnected by struts.

6. A non-transitory computer-readable medium encoding instructions which, when executed by a microprocessor of a computer system, cause the computer system to:
generate a first display of a graphical representation of a first fixation ring of an orthopedic treatment device superimposed on a representation of a first bone segment in a first view;
concurrently with generating the first display, generate a second display of the graphical representation of the first fixation ring of the orthopedic treatment device superimposed on the representation of the first bone segment in a second view at a different angle from the first view;
receive user input entered on the first display of the graphical representation of the first fixation ring of the orthopedic treatment device, the user input controlling a motion of the graphical representation of the first fixation ring of the orthopedic treatment device; and
in response to receiving the user input, update the first display of the graphical representation of the first fixation ring of the orthopedic treatment device and the second display of the graphical representation of the first fixation ring of the orthopedic treatment device to reflect the motion of the graphical representation of the first fixation ring of the synthetic orthopedic treatment device,
wherein the motion comprises at least one of a rotation motion and a translation motion.

7. The non-transitory computer readable medium of claim 6 , wherein the first view is an anterior-posterior (AP) view, and the second view is a lateral view.

8. The non-transitory computer readable medium of claim 6 , wherein the first view is a lateral view, and the second view is an anterior-posterior (AP) view.

9. The non-transitory computer readable medium of claim 6 , wherein the motion comprises the rotation motion and the translation motion.

10. The non-transitory computer readable medium of claim 6 , wherein the orthopedic treatment device is an external fixator comprising the first fixation ring and a second fixation ring interconnected by struts.

11. A method of updating a graphical representation of a first fixation ring of an orthopedic treatment device, comprising:
generating a first display of the graphical representation of the first fixation ring of the orthopedic treatment device superimposed on a representation of a first bone segment in a first view;
concurrently with generating the first display, generating a second display of the graphical representation of the first fixation ring of the orthopedic treatment device superimposed on the representation of the first bone segment in a second view at a different angle from the first view;
entering user input on the first display of the graphical representation of the first fixation ring of the orthopedic treatment device, the user input controlling a motion of the graphical representation of the first fixation ring of the orthopedic treatment device; and
in response to entering the user input, updating the first display of the graphical representation of the first fixation ring of the orthopedic treatment device and the second display of the graphical representation of the first fixation ring of the orthopedic treatment device to reflect the motion of the graphical representation of the first fixation ring of the synthetic orthopedic treatment device,
wherein the motion comprises at least one of a rotation motion and a translation motion.

12. The method of claim 11 , wherein the first view is an anterior- posterior (AP) view, and the second view is a lateral view.

13. The method of claim 11 , wherein the first view is a lateral view, and the second view is an anterior-posterior (AP) view.

14. The method of claim 11 , wherein the motion comprises the rotation motion and the translation motion.

15. The method of claim 11 , wherein the orthopedic treatment device is an external fixator comprising the first fixation ring and a second fixation ring interconnected by struts.
