Claim 0:
1. A method of determining an optimal, long-term orthopedic implant configuration for a spinal alignment correction procedure in a subject, comprising:
(a) based on a set of preoperative medical images, determining initial values and a desired corrected set of values of selected spinal alignment parameters;
(b) selecting at least one potential implant for correcting the selected spinal alignment parameters;
(c) digitally positioning, in the set of preoperative medical images, the at least one potential implant for correcting the selected spinal alignment parameters, to create at least one virtual configuration of at least one potential bone-implant combination;
(d) determining an acceptable long-term stress score range for the at least one virtual configuration based on (i) clinically relevant data of the subject, and (ii) similarly characterized cases from a medical database;
(e) for the at least one virtual configuration, (i) performing finite element analysis on the at least one potential implant to determine stress scores along an extent of the at least one potential implant; and (ii) calculating expected corrected values of the selected spinal alignment parameters;
(f) select an implant from the at least one potential implant, which minimizes the long-term stress score;
(g) intraoperatively, inserting the selected implant into a spine of the subject, the inserted implant being adapted to have at least one mode of stress detection;
(h) using the at least one mode of stress detection, intraoperatively measuring a stress score at each point along a length of the inserted implant; and
(i) modifying the inserted implant and repeating steps (g) to (h) until an implant configuration falling within the acceptable long-term stress score range is achieved.
