| Outline of Final Research Achievements |
To investigate kinematics and kinetics of the hip joint,3D-MRI with voxel-based registration method for the native hips,and fluoroscopy with 2d/3d registration method for the hip with total hip arthroplasty (THA) were applied.Muscle strength was also evaluated using hand-held-dynamometer. Translation was significantly larger in dysplastic hips than normal hips. Translation at specific hip position was significantly larger in the normal aged women than that in the normal aged women. In the evaluation of squatting after THA, flexion angle increased significantly at 1 year postoperatively without following significant increase by 3 years. Pelvic posterior tilt decreased significantly at 1 year postoperatively without following significant decrease by 3 years. Muscle strength around th hip joint increased postoperatively and that exceeded the preoperative value at 3 months postoperatively.
