Purpose: The purpose of this study is to evaluate the usefulness of a modular total hip system for combined anteversion in cementless modular total hip arthroplasty. Materials and Methods: We performed twenty cementless modular total hip arthroplasty procedures. The patients lay in lateral position and 15。internal rotation of the thigh. The surgeon inserted an acetabular cup component first, followed by a femoral component. He selected an appropriate modular neck component using an

Results: The average measurement of anteversion of the acetabular cup was 15.9±2.9。and anteversion of the femoral stem was 15.2±11.9。 . Then, the combined anteversion was calculated to 24.0±8.2。 . Significant difference was observed between combined anteversion and theoretical combined anteversion. Conclusion: The method using an intra-operative manual combined anteversion test cannot realize the theoretical combined anteversion in cementless modular hip arthroplasty.
