Femoral version and neck shaft angle.
We measured femoral anteversion by the Kingsley-Olmsted method in 24 unpaired, dry femurs. When the head and neck of the same femurs were measured by computed tomography (CT) scan, measurement was 5 degrees less than the Kingsley-Olmsted method, whereas ultrasound of the head and neck was 5 degrees higher. An anterior flat plane was also defined to help measure anteversion in patients with a high neck shaft angle. Physical and ultrasound measurement correlated well with the previous measurement by the Kingsley-Olmsted method and CT scan of anteversion. Although measurement by CT scan and ultrasound are different their results are both reproducible and measure the same parameters; however, ultrasound measurement yields a number approximately 10 degrees higher.
