Abstract
A system and method that acquire (i) at least a reference image including one of a preoperative image of a surgical site with skeletal and articulating bones and a contralateral image on an opposite side of the patient from the surgical site and (ii) at least an intraoperative image of the site after an implant has been affixed to the articulating bone. The system generates at least one reference landmark point on at least one anatomical feature on the articulating bone in the reference image and at least one intraoperative landmark point on that anatomical feature in the intraoperative image. The reference and intraoperative images are compared and differences between the orientation of the articulating bone in the two images are utilized to analyze at least one of offset and length differential.
