| Abstract(in English) | This paper describes a 3D automated preoperative planning procedure of the femoral stem for Total Hip Arthrorplasty (THA). We have reported a method which maximizes the fitness with the femoral cortical bone. However, there was a problem that the error of the stem neck direction was large. In this paper, we focused attention on the doctor's criteria that the stem neck direction corresponded with the primary axis of the femoral canal area in axial plane, and we estimated this direction using principal component analysis of the projected femoral canal shape. As a result, the error of the stem neck direction was less than 2.6 deg. in 5 cases out of 7 cases. We think that the procedure is acceptable as the system which can estimate the 6 degrees of freedom (position and rotation). |
