Retracted: Analysis of Medialisation of the Femoral Head in Periacetabular Osteotomy Using Three-Dimensional Computed Tomography
Search this article
Description
Periacetabular osteotomy has been established as an effective treatment for osteoarthritis caused by developmental dysplasia of the hip. Medialisation of the femoral head during periacetabular osteotomy is crucial for providing significant reduction in joint contact stress. The purpose of this study was to evaluate effective procedures for medialisation of the femoral head during periacetabular osteotomy using three-dimensional computed tomography (3DCT).Thirty hips in 30 patients with hip dysplasia underwent both radiographic and 3DCT scans before and after surgery. The direction of the rotation of the acetabular fragment and movement of the femoral head were evaluated to analyse which parameters contributed to medialisation of the femoral head.Anterior coverage of the acetabular fragment and internal rotation in the axial plane contributed to both medialisation of the femoral head and anteversion of the retroverted acetabulum.This study demonstrated that re-orientation of the acetabulum was spatially confirmed by the method using 3DCT images.
