Definitions

  • a computer-implemented method for determining a transformation for anatomically aligning fragments of a broken bone comprises acquiring an image of a broken bone of a subject, wherein the bone is broken into two or more fragments.
  • the method also comprises acquiring a model of a corresponding unbroken bone and at least one parameter defining one or more deformations to the model that are permitted when fitting portions of the model of the unbroken bone to corresponding fragments of the broken bone, fitting portions of the model of the unbroken bone to corresponding fragments of the broken bone based on the at least one parameter, and determining a transformation that anatomically aligns the fragments of the broken bone with the corresponding portions of the model.
  • the apparatus 100 may also comprise a memory 106 configured to store program code that can be executed by the processor 102 to perform the method described herein.
  • one or more memories 106 may be external to (i.e. separate to or remote from) the apparatus 100.
  • one or more memories 106 may be part of another device.
  • a memory 106 can be used to store images, information, data, signals and measurements acquired or made by the processor 102 of the apparatus 100 or from any interfaces, memories or devices that are external to the apparatus 100.
  • the processor 102 may be configured to control the memory 106 to store the images, information, data, signals and measurements.
  • portions of the model of the unbroken bone are fitted to corresponding fragments of the broken bone based on the at least one parameter. More specifically, the processor 102 of the apparatus 100 performs the fitting of portions of the model of the unbroken bone to corresponding fragments of the broken bone.
  • the transformation that anatomically aligns a fragment of the broken bone with a corresponding portion of the model may be determined to be of the same magnitude as the transformation that is necessary to fit the portion of the model of the unbroken bone to the corresponding fragment of the broken bone.
  • the transformation that anatomically aligns a fragment of the broken bone with a corresponding portion of the model may be determined to be the reverse (or inverse or opposite) of the transformation that is necessary to fit the portion of the model of the unbroken bone to the corresponding fragment of the broken bone.
  • the translation that anatomically aligns the fragment of the broken bone with the corresponding portion of the model can be determined to be a rotation by 10 degrees in an anticlockwise direction about the longitudinal axis of the broken bone and a translation by 10 cm along the longitudinal axis of the unbroken bone in a second direction, where the second direction is opposite the first direction.
  • a transformation can be determined that anatomically realigns the fragments of the broken bone with each other.
  • the transformations necessary to fit the portion of the model of the unbroken bone to the corresponding fragment of the broken bone and thus also the transformations necessary to anatomically align the fragment of the broken bone with the corresponding portion of the model can be more complex but the same general principles described above apply.
  • the method may further comprise outputting the determined transformation.
  • the processor 102 of the apparatus 100 may output the determined transformation.
  • the processor 102 may control a user interface 104 to output (or render, display, or provide) the determined transformation that anatomically aligns the fragments of the broken bone with the corresponding portions of the model and/or may control a memory 106 to store the determined transformation that anatomically aligns the fragments of the broken bone with the corresponding portions of the model.
  • Figure 4 shows an example model of a corresponding unbroken bone to the broken bone of the subject illustrated in Figure 3.
  • the model of the corresponding unbroken bone is a model of an unbroken left femur.
  • the model of the corresponding unbroken bone is divided into three portions that each correspond to one of the three fragments of the broken bone in the image.
  • the three portions of the model of the unbroken bone are fitted to the corresponding fragments of the broken bone based on the at least one parameter, as described earlier (as shown in Figure 4 on the left).
