INTRAOPERATIVE ROD GENERATION BASED ON AUTO IMPLANT DETECTION

Abstract:

A method and system for improving spinal alignment parameters of a subject, by planning the shape of an intervertebral rod for attaching to previously implanted hardware whose positions and orientations are known from intraoperative images. Once the planned shape of the rod has been prepared, determining if, when attached to the inserted hardware, a spine configuration is achieved having acceptable values of selected spinal alignment parameters. If not, the shape of the rod is amended iteratively, until the selected spinal alignment parameters have acceptable values with attachability to the implanted hardware. If, after a predetermined number of iterations, the amended shape of the rod still does not achieve acceptable values of spinal alignment parameters, while maintaining attachability to the implanted hardware, performing a spinal manipulation procedure on at least one vertebra of the spine to increase the attachability of the rod to the implanted hardware.
