| Research Abstract |
In total hip arthroplasty, implant orientation is important for avoiding prosthetic impingement. However, key information has lacked for optimal cup orientation such as patient hip range of motion needed for daily life, cup safe zone without prosthetic impingement among the range of motion and pelvic reference frame for cup implantation. We confirmed that cup safe zone was extremely narrow and that functional pelvic plane was suitable for reference frame for cup by using 4 dimensional motion analysis and simulation technique. We recommended using CT-based navigation system for minimizing risk of impingement related complications.
