抄録

We have been working on development of automated preoperative planning system for total hip arthroplasty. Although we have already developed automated planning procedures for implants which are inserted into the host bone, there were no automated methods to adjust the integrated planning with considering pelvic and femoral side conditions. In this study, we enhanced the automated procedure to integrate both sides of the plannings by minimizing limb length difference and assuring sufficient range of motion. The system simulates all combination of implants and adopts candidates of cup placement to fulfill the restrictions for optimal placement. We applied this algorithm to 15 cases and confirmed that the automated plannings were optimized successfully in 13 cases. This showed a usefulness of the automated method as an assistant tool for surgical planning.
