Problems solved by technology

Surgeons may repeat this trial process many times without guidance to predict how changing the modular prosthesis option will affect leg length and offset
[0006] This process of retrial is time consuming for the surgeon and increases the risk of femur fracture due to the repetitive process of dislocating the hip to change the modular prosthesis selection

Embodiment Construction

[0039] The present invention may be implemented by systems and methods that acquire (i) a preoperative image of a surgical site including bone and articular bone and a contralateral image in a contralateral image of the patient's opposite side from the surgical site at least one reference image of one, and (ii) at least one intraoperative image of the site after the implant has been attached to the articular bone. In some configurations, the system generates at least one reference fixed point on at least the skeletal bone in the reference image and at least one intraoperative fixed point on at least the skeletal bone in the intraoperative image. The orientation of the implant is identified in the intraoperative image, preferably including the positions of the first and second centers of rotation co-located in the intraoperative image. (i) at least one of the first digital implant representation is aligned with the bony component and with at least an intraoperative fixed point,...

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 preferably generates at least one reference stationary point on at least the skeletal bone in the reference image and at least one intraoperative stationary point on at least the skeletal bone in the intraoperative image. The location of the implant is identified in the intraoperative image, preferably including the position of first and second centers of rotation, which are digitally represented and copied into the reference image to analyze at least one of offset and length differential.
