Outline of Final Research Achievements

We have developed the computer simulation system combined with the navigation system for elbow arthroscopic surgery. The 3-D shape of lesion was illustrated in the preoperative computer simulation using the motion analysis method. Introducing those data to the navigation system allows to visualize the lesion on the navigation monitor during actual surgery. We validated the registration accuracy of the navigation system for the elbow using 3-D plastic models for practical clinical application. The total registration accuracy was 0.96mm for the humerus and 0.85mm for the ulna. No significant differences were found in the registration accuracy for the humerus and ulna among the three observers.
From the results of this preliminary study, the arthroscopically assisted registration procedure is sufficiently feasible and accurate for application of the navigation system to arthroscopic debridement arthroplasty in clinical settings.
