Deviation of the centre of rotation of the femoral head in dysplastic hip joints

Hip instability may be based not only on some mismatch between the size of the femoral head and acetabulum but also on the deviation of the centre of rotation of the femoral head. The aim of this study was to compare the differences between the centre of rotation of the femoral head and that of the acetabulum in normal and dysplastic hips. Thirty dysplastic hips and 30 control hips without dysplastic hip were included in this study. Computed...
