Effects of the position of the components on hip motion in the virtual total hip replacement
Objective To explore the effects of the position of components on hip joint motion in the virtual total hip replacement. Methods Based on digital CT images, a three-dimensional computer model of the hip after total hip replacement were created by the use of computer three-dimensional reconstruction and virtual surgery technology. The model was designed to simulate joint motion and get maximum range of motion before joint impingement at different positions. Results (1) Excerpt for the range of external rotation, the increase of acetabular abduction induced the increase of the range of flexion, extension and internal rotation at 90° flexion. The increase of the acetabular and femoral anteversion induced the increase of the range of flexion and internal rotation at 90° flexion, but the decrease of the range of extension and external rotation. (2) To meet the needs of daily activities, the greater acetabular abduction required appropriately decreased acetabular anteversion. The relative position of acetabular abduction and femoral anteversion depended on the acetabular anteversion. Conclusions It's important to confirm the relative position of the components during the total hip replacement. Furthermore, this result is valuable for guiding the prosthesis implantation in reversion surgery and the range of daily activities in patients with postoperative dislocation.
