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.

Orthopedic fixation control and manipulation

First and second images are displayed of anatomical structure segments with an attached fixator. Indications may be received of first image hinge locations of a plurality of hinges of the fixator in the first image. Projected second image hinge locations may be determined based at least in part on the first image hinge locations. Hinge candidates may be detected in the second image having shapes associated with the plurality of hinges. The hinges candidates may be detected by computer software using automated software-based image analysis techniques. Adjusted second image hinge locations may then be calculated based at least in part on the projected second image hinge locations and candidate second image hinge locations. The adjusted second image hinge locations may be used to determine physical locations of the fixator and anatomical structure segments in three-dimensional space, which may be used to determine manipulations to the fixator for deformity correction.

Hinge detection for orthopedic fixation

A computer-implemented method for producing a treatment plan to control manipulation of a fixation apparatus including a first element and a second ring and struts to correct an anatomical structure deformity of first and second anatomical structure segments, including: 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 and ring deformation information; receiving, by the computing system, images of the fixation apparatus and the first and the second anatomical structure segments attached thereto; determining, by the computing system, based on the configuration information and the received images, positions and orientations of the first and the second anatomical structure segments in three-dimensional space relative to the fixation apparatus; determining the hole locations of the first element based upon the deformation information; determining, by the computing system, manipulations to the fixation apparatus for correction of the anatomical structure deformity, the manipulations comprising adjustments to the struts based upon the determined hole location of the first element; and providing, by the computing system, to one or more users, indications of the manipulations to the fixation apparatus.

Perspective frame matching process for deformed fixation rings

A plurality of three-dimensional fixator graphical representations may include graphical indications of a strut swap range. A plurality of replaced strut graphical representations may change from a first rendering state in a swap start fixator graphical representation to a second rendering state in a swap end fixator graphical representation. A plurality of replacement graphical representations may change from the second rendering state in the swap start fixator graphical representation to the first rendering state in the swap end fixator graphical representation. In some examples, the plurality of replaced strut graphical representations may gradually fade out from a swap start stage to a swap end stage, and the plurality of replacement strut graphical representations may gradually fade in from a swap start stage to a swap end stage. Additionally, a treatment plan including at least one interfamily strut swap may be generated for manipulating a fixator to correct a deformity.

Orthopedic fixation strut swapping

A guided frame matching technique may be employed in which a graphical projection of a fixator is used to guide and assist a user in identifying fixator elements within an image. Upon being overlaid on an image, the graphical projection of fixator may be manipulated to align with, and overlay, fixator elements displayed within the image. Additionally, a three-dimensional overview of an imaging scene of the fixator may be generated. The three-dimensional overview may include a three-dimensional graphical model that displays representations of images of the fixator attached to anatomical structure segments as well as representations of imaging sources, reference locations, fixator elements, and anatomical structure segments. When the images are not truly orthogonal, a modified second image representation may be displayed to represent a second image that is truly orthogonal to a first image.
