Abstract

A fixation apparatus may be attached to first and second anatomical structure segments. Images of the fixation apparatus and the attached anatomical structure segments may then be captured. In some examples, the images need not necessarily be orthogonal with respect to one another. Configuration information associated with the fixation apparatus may then be received. Additionally, first image information may be received, for example including indications of one or more locations, within the images, of at least part of one or more elements of the fixation apparatus. Additionally, second image information may be received, for example including indications of one or more locations, within the images, of at least part of the first and the second anatomical structure segments. Manipulations to the fixation apparatus for correction of the anatomical structure deformity may then be determined, and indications of the determined manipulations may then be provided to one or more users.

First claim

What is claimed:

1. A computer-implemented method for controlling manipulation of a fixation apparatus including rings and struts to correct an anatomical structure deformity of first and second anatomical structure segments comprising:
receiving, using one or more graphical user interfaces of a computing system, configuration information associated with the fixation apparatus, the configuration information comprising one or more geometric characteristics of one or more elements of the fixation apparatus;
displaying, using the one or more graphical user interfaces, images of the fixation apparatus and the first and the second anatomical structure segments attached thereto;
receiving, using the one or more graphical user interfaces, first image information comprising indications of one or more locations, within the images, of at least part of the one or more elements of the fixation apparatus, wherein the one or more elements of the fixation apparatus comprise a hinge of the fixation apparatus, wherein the one or more locations comprise a location of the hinge, wherein an enlarged view of an area of one of the images is displayed, the enlarged view depicting the hinge of the fixation apparatus, and wherein the enlarged view allows a user to manipulate the location of the hinge;
receiving, using the one or more graphical user interfaces, second image information comprising indications of one or more locations, within the images, of at least part of the first and the second anatomical structure segments;
determining, by the computing system, based at least in part on the configuration information, the first image information, and the second image information, positions and orientations of the first and the second anatomical structure segments in three-dimensional space;
determining, by the computing system, manipulations to the fixation apparatus for correction of the anatomical structure deformity, the manipulations comprising planned adjustment lengths by which to adjust the struts; and
providing, by the computing system, to one or more users, indications of the manipulations to the fixation apparatus.

2. The computer-implemented method of claim 1 , wherein the configuration information comprises a length of one or more struts of the fixation apparatus.

3. The computer-implemented method of claim 1 , wherein the configuration information comprises indications of mounting points at which one or more struts are mounted.

4. The computer-implemented method of claim 1 , further comprising providing, using the one or more graphical user interfaces, a graphical representation of the fixation apparatus based at least in part on the configuration information.

5. The computer-implemented method of claim 4 , wherein the graphical representation of the fixation apparatus includes color-coded graphical representations of struts.

6. The computer-implemented method of claim 5 , wherein the color-coded graphical representations of the struts in the graphical representation of the fixation apparatus match a physical color-coding of the struts in the fixation apparatus.

7. The computer-implemented method of claim 1 , wherein a reference ring of the fixation apparatus is non-orthogonal with respect to an anatomical structure on which it is mounted.

8. The computer-implemented method of claim 1 , wherein the determining the manipulations is performed based, at least in part, on instructions to perform axial movement in an initial part of treatment.

9. The computer-implemented method of claim 1 , wherein the determining the manipulations is performed based, at least in part, on instructions to perform two adjustments per day.

10. The computer-implemented method of claim 1 , wherein the determining the manipulations is performed based, at least in part, on a specified duration of treatment.

11. The computer-implemented method of claim 1 , wherein the determining the manipulations is performed based, at least in part, on a specified rate of distraction.

12. The computer-implemented method of claim 1 , wherein the determining the manipulations is performed based, at least in part, on instructions to generate an axial gap to ensure anatomical structure clearance.

13. The computer-implemented method of claim 1 , further comprising generating one or more graphical representations of a position and an orientation of the first and second anatomical structure segments and rings of the fixation apparatus.

14. The computer-implemented method of claim 13 , wherein the one or more graphical representations comprise day-by-day graphical representations of a position and an orientation of the first and second anatomical structure segments and the rings of the fixation apparatus throughout treatment for the anatomical structure deformity.

15. The computer-implemented method of claim 1 , wherein the images comprise non-orthogonal images.

16. One or more non-transitory computer-readable storage media having stored thereon instructions that, upon execution by one or more computing devices, cause the one or more compute nodes to perform operations for controlling manipulation of a fixation apparatus including rings and struts to correct an anatomical structure deformity of first and second anatomical structure segments, the operations comprising:
receiving, using one or more graphical user interfaces of the one or more computing devices, configuration information associated with the fixation apparatus, the configuration information comprising one or more geometric characteristics of one or more elements of the fixation apparatus;
displaying, using the one or more graphical user interfaces, images of the fixation apparatus and the first and the second anatomical structure segments attached thereto;
receiving, using the one or more graphical user interfaces, first image information comprising indications of one or more locations, within the images, of at least part of the one or more elements of the fixation apparatus, wherein the one or more elements of the fixation apparatus comprise a hinge of the fixation apparatus, wherein the one or more locations comprise a location of the hinge, wherein an enlarged view of an area of one of the images is displayed, the enlarged view depicting the hinge of the fixation apparatus, and wherein the enlarged view allows a user to manipulate the location of the hinge;
receiving, using the one or more graphical user interfaces, second image information comprising indications of one or more locations, within the images, of at least part of the first and the second anatomical structure segments;
determining, based at least in part on the configuration information, the first image information, and the second image information, positions and orientations of the first and the second anatomical structure segments in three-dimensional space;
determining manipulations to the fixation apparatus for correction of the anatomical structure deformity, the manipulations comprising planned adjustment lengths by which to adjust the struts; and
providing, by the computing system, to one or more users, indications of the manipulations to the fixation apparatus.

17. A computing system for controlling manipulation of a fixation apparatus including rings and struts to correct an anatomical structure deformity of first and second anatomical structure segments comprising:
one or more processors; and
one or more memories having stored therein instructions that, upon execution by the one or more processors, cause the computing system perform operations comprising:
receiving, using one or more graphical user
