Embodiment Construction
[0042] In this detailed description and the appended claims, the terms "proximal", "distal", "anterior", "rear", "medial", "lateral", "superior", and "inferior" Defined by their standard usage, to denote a specific part of a bone or implant in terms of its relative position to natural bone or a referenced locale. For example, "proximal" refers to the part of the implant closest to the torso, while "distal" refers to the part of the implant furthest from the torso. For orientation words, "anterior" refers to the direction toward the front of the body, "posterior" refers to the direction toward the back of the body, "medial" refers to the direction toward the midline of the body, and "lateral" refers to the side of the body Or a direction away from the midline of the body, "superior" refers to a direction above, and "inferior" refers to a direction below another object or structure. Additionally, for the purposes of the present invention, when referring to a device, the term "p...

The present disclosure provides methods for determining an adjustment prescription of an external fixation device affixed to anatomical structures. The methods include obtaining at least two digital radiographic images of differing orientations of the external fixation device and anatomical structures in an initial arrangement. The methods also include identifying fiducial markers of the externalfixation device and an axis of the anatomical structures in the at least two radiographic images. The methods include providing a virtual manipulatable three-dimensional model of the external fixationdevice and the anatomical structures. The methods include providing an adjustment prescription of strut assemblies of the external fixation device based on a user determined desired arrangement of the anatomical structures that rearranges the anatomical structures from the initial arrangement to the desired arrangement via at least one user selected waypoint. The user determined desired arrangement of the anatomical structures is determined via the three-dimensional model.
Description
[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Patent Application No. 62 / 549,841, entitled "Method and System for Determining Adjustment Prescriptions for External Fixation Devices," filed August 24, 2017, the entire contents of which are expressly incorporated herein by reference Incorporated into this article. technical field [0003] Embodiments of the invention relate to the treatment of musculoskeletal disorders including bone fractures. More specifically, methods and systems for securing and placing one or more bone segments in a desired position are disclosed. In some embodiments of the invention, methods and systems are used to generate computer models of fixation devices and bone segments. By manipulating the model, regardless of the initial configuration of the fixation device, the desired position of the bone segment and the operations performed on the external fixation device to achieve this desired p...
