Abstract: A method of generating a correction plan for correcting a deformed bone includes inputting to a computer system a first image of the deformed bone in a first plane and inputting to the computer system a second image of the deformed bone in a second plane. Image processing techniques are employed to identify a plurality of anatomical landmarks of the deformed bone in the first image. The first image of the deformed bone is displayed on a display device. A graphical of the deformed bone is autonomously generated and graphically overlaid on the first image of the deformed bone on the display device, the graphical template including a plurality of lines, each line connected at each end to a landmark point corresponding to one of the anatomical landmarks. A model of the deformed bone may be autonomously generated based on the graphical template.

Abstract: A system for processing patient data associated with a joint of a patient. The system including a computing device executing instructions to provide a bone model of the joint that is representative of the joint of the patient in a first pose. The instructions further including rearranging the bone models relative to each other to mimic a second pose of the joint of the patient from at least one image or model representative of the joint of the patient in the second pose. The instructions further including planning a joint replacement procedure with the bone models after rearranging the plurality of bone models to mimic the second pose of the joint of the patient from the at least one image or model representative of the joint of the patient in the second pose.

Abstract: A system for processing patient data associated with a joint of a patient. The system comprising a computing device executing instructions to generate a 3D patient bone model of the joint in a non-weighted pose. The instructions rearrange 3D first and second bone models in order to mimic a weighted pose of the joint of the patient from a 2D image of the joint of the patient in a weighted pose by performing the steps of: generating a plurality of 2D projections of poses of the 3D patient bone model; comparing the plurality of 2D projections to contour lines of the first bone and the second bone in the 2D image; identifying particular 2D projections that best-fit a shape and size of the contour lines; and arranging the 3D first and second bone models relative to each other according to orientations represented by the particular 2D projections that were identified.

Abstract: A computer process including receiving first patient bone data of a patient leg and foot in a first pose, the first pose comprising a position and orientation of the patient leg relative to the patient foot as defined in the first patient bone data. The computer process may further include receiving second patient bone data of the patient leg and foot in a second pose, the second pose comprising a position and orientation of the patient leg relative to the patient foot as defined in the second patient bone data. The computer process may further include generating a 3D bone model of the patient leg and foot. Finally, the computer process may include modifying the 3D bone model of the patient leg and foot such that the plurality of 3D bone models are reoriented into a third pose that matches the second pose.
