1. A computer-implemented method for planning patient-specific spine surgical correction, comprising the steps of:
obtaining patient imaging data, the imaging data including at least A/P and Lateral radiographic images and a 3D imaging dataset;
creating a virtual model by segmenting at least one bone in the 3D imaging dataset;
assigning reference geometry to each segmented bone to define different parts of anatomy;
creating a 3D weight-bearing virtual model that consists of segmentation from the 3D imaging dataset by:
calibrating at least one of the A/P and Lateral radiographic images to the CT scan;
determining whether all anatomy required to measure spinopelvic parameters is not included in the 3D imaging dataset;
segmenting at least one bone that was not included in the 3D imaging dataset;
aligning the segmented bones in 3D space from the 3D imaging dataset to the A/P and Lateral radiographic images;
measuring pre-operative parameters on the 3D weight-bearing virtual model by using the reference geometry assigned to the segmented bones;
providing the virtual model to the surgeon including measurements for the surgeon;
receiving input from the surgeon the desired surgical procedure to be performed and surgical goals from that procedure;
modifying the weight-bearing virtual model based on surgeon input of planned surgical procedure to create an operative plan virtual model representative of the surgeon's desired surgical procedure and surgical goals;
analyzing the operative plan virtual model for acceptability and further modifying the model if the operative plan virtual model is not acceptable;
designing one or more implants to fit the virtual model; and
presenting the operative plan virtual model to the surgeon as a surgical plan for approval.
