| Outline of Final Research Achievements |
We developed a 3-dimensional motion analysis system that enables to visualize Triangular Fibrocartilage Complex (TFCC) using computed tomography with arthrography. We analysed wrists with osteoarthritis, TFCC injury, scapholunate ligament injury, and normal subjects. We found the length of simulated radioulnar ligaments increased when the wrist joint was loaded in an extended position. The four-corner kinematics of the wrist joint are different between type 1 and 2 lunates. The hamate contacted the lunate in ulnar deviation and ulnar flexion of wrists with type 2 lunates but not with type 1. We found The ulnotriquetral ligament tenodesis well stabilized the distal radioulnar joint in case of the TFCC foveal tear in biomechanical study.
