Orthopedic treatment device co-display systems and methods
In some embodiments, a synthetic (virtual) orthopedic treatment device (e.g. a virtual external fixator representing a physical fixator attachable to a patients 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.
1. A computer-implemented method comprising employing at least one processor to execute instructions to:
generate a display of a graphical representation of a first ring of an external fixator superimposed on a display of a digital medical image, the digital medical image displaying a view of a patient's bone and the external fixator attached to the patient's bone, the external fixator including a second ring connected to the first ring by a plurality of struts;
receive first ring position user input entered graphically on the display of the graphical representation of the first ring, the first ring position user input controlling translation and/or rotation of the graphical representation of the first ring;
in response to receiving first ring position user input, generate a display of an updated graphical representation of the first ring superimposed on the display of the digital medical image, the updated graphical representation of the first ring reflecting the translation and/or rotation of the graphical representation of the first ring, the updated graphical representation of the first ring matching a position and orientation of the first ring in the digital medical image.
2. The method of claim 1 , wherein the first ring position user input controls rotation of the graphical representation of the first ring.
3. The method of claim 2 , wherein the rotation of the graphical representation of the first ring is azimuthal rotation.
4. The method of claim 3 , further comprising employing the at least one processor to execute instructions to generate a display of a graphical representation of the plurality of struts superimposed on the display of the digital medical image.
5. The method of claim 4 , further comprising employing the at least one processor to execute instructions to receive strut position user input.
6. The method of claim 5 , wherein the strut position user input identifies a 3D position of each strut of the plurality of struts.
7. The method of claim 6 , further comprising employing the at least one processor to execute instructions to, in response to receiving the first ring position user input, generate a display of an updated graphical representation of the plurality of struts superimposed on the display of the digital medical image, after the strut position user input is received.
8. The method of claim 7 , wherein the updated graphical representation of the plurality of struts reflects the azimuthal rotation of the graphical representation of the plurality of struts.
9. The method of claim 1 , wherein the graphical representation of the first ring is an ellipse.
10. The method of claim 9 , wherein the ellipse is a tilted ellipse.
11. The method of claim 1 , wherein the display of the digital medical image comprises a first digital medical image and a second digital medical image, the first digital medical image and second digital medical image displaying views from different angles of the patient's bone.
12. The method of claim 11 , further comprising employing the at least one processor to execute instructions to perform a relative scaling of the first digital medical image and the second digital medical image.
13. The method of claim 1 , further comprising employing the at least one processor to generate a display of a first line segment extending along an axis of a first bone segment of the patient's bone shown in the display of the digital medical image by detecting locations of corresponding bone segment graphical user input.
14. The method of claim 13 , wherein the bone segment graphical user input includes mouse clicks at opposite ends of the first bone segment shown in the display of the digital medical image.
15. The method of claim 1 , further comprising employing the at least one processor to, for each of the plurality of struts, receive strut attachment point user input representing a first actual point of attachment of the strut to the first ring.
16. The method of claim 15 , wherein the first actual point of attachment of the strut to the first ring is a hole in the first ring.
17. The method of claim 1 , further comprising employing the at least one processor to generate a strut line segment for each of the plurality of struts and display the strut line segment on the display such that the strut line segment overlies a corresponding one of the plurality of struts in the digital medical image.
18. The method of claim 17 , further comprising employing the processor to generate a bone deformity correction plan specifying, for each of the plurality of struts, a sequence of strut lengths to be used in a bone deformity correction treatment.
19. The method of claim 17 , wherein the display of the graphical representation of the first ring superimposed on the display of the digital medical image is displayed simultaneously with the strut line segments.
