The use of combined anteversion in total hip arthroplasty for patients with developmental dysplasia of the hip.

The combined anteversion technique has been proposed recently and proved to be an applicable technique in general THA. The corresponding author routinely applied this approach to DDH patients in clinical practice. The current study aimed to provide clinical evidence for this approach. We studied 35 DDH patients (47 hips). Every patient underwent pelvic CT scans before and after surgery and the HHs was recorded. The data indicate a high accuracy of controlling components orientation and satisfactory clinical outcomes. Using this approach, we reduced dislocation risk and got better impingement free range of motion. Therefore, we conclude that combined anteversion is effective for DDH patients who receive a THA. This approach could guarantee stable and functioning joints for DDH patients receiving THA.
