| Abstract(in English) | Objective and accurate preoperative planning of implant size selection and positioning is desirable for total hip arthroplasty (THA). In this paper, an improved algorithm for acetabular cup size selection and placement in automated THA planning is described. The center-edge angle and cup coverage ratio are used to evaluate the fixation strength. In addition, the thickness of anterior, posterior and medial wall out of an acetabular cup were measured so as not to break the acetabular rim and the inner cortex of the pelvis. These factors are newly incorporated into the optimal determination procedure of the cup size and position. An experienced surgeon evaluated that the final solutions obtained using the automated method were acceptable, which showed a potential usefulness of the automated method. We confirmed that the method could be applied to secondary osteoarthritis due to hip dysplasia. Future work will include the validation of the method using more cases and its clinical application. |
