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.
Claims21
A computer-implemented method comprising employing at least one processor to execute instructions to:
- generate a display of an ellipse superimposed on a display of at least one digital medical image, the at least one digital medical image displaying a view of a patient's anatomical structure, the ellipse being a graphical representation of a first ring of a synthetic external fixator representing a physical external fixator attached to the patient's anatomical structure, the physical external fixator comprising first and second rings interconnected by a plurality of struts;
- generate a display of a first line segment extending along an axis of a first bone segment shown in the display of the at least one digital medical image by detecting locations of corresponding bone segment graphical user input;
- for each strut, receive strut attachment point user input representing a first actual point of attachment of the strut to the first ring and a second actual point of attachment of the strut to the second ring;
- generate a strut line segment for each strut and displaying 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;
- and
- generate a bone deformity correction plan specifying for each strut a sequence of strut lengths to be used in a bone deformity correction treatment.

A computer system comprising at least one microprocessor configured to execute instructions to:
- generate a display of an ellipse superimposed on a display of at least one digital medical image, the at least one digital medical image displaying a view of a patient's anatomical structure, the ellipse being a graphical representation of a first ring of a synthetic external fixator representing a physical external fixator attached to the patient's anatomical structure, the physical external fixator comprising first and second rings interconnected by a plurality of struts;
- generate a display of a first line segment extending along an axis of a first bone segment shown in the display of the at least one digital medical image by detecting locations of corresponding bone segment graphical user input;
- for each strut, receive strut attachment point user input representing a first actual point of attachment of the strut to the first ring and a second actual point of attachment of the strut to the second ring;
- generate a strut line segment for each strut and displaying 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;
- and
- generate a bone deformity correction plan specifying for each strut a sequence of strut lengths to be used in a bone deformity correction treatment.

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 display of an ellipse superimposed on a display of at least one digital medical image, the at least one digital medical image displaying a view of a patient's anatomical structure, the ellipse being a graphical representation of a first ring of a synthetic external fixator representing a physical external fixator attached to the patient's anatomical structure, the physical external fixator comprising first and second rings interconnected by a plurality of struts;
- generate a display of a first line segment extending along an axis of a first bone segment shown in the display of the at least one digital medical image by detecting locations of corresponding bone segment graphical user input;
- for each strut, receive strut attachment point user input representing a first actual point of attachment of the strut to the first ring and a second actual point of attachment of the strut to the second ring;
- generate a strut line segment for each strut and displaying 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;
- and
- generate a bone deformity correction plan specifying for each strut a sequence of strut lengths to be used in a bone deformity correction treatment.
