[Computed tomographic measurement of the angle of torsion of the femoral neck. Experimental reliability study on dry bone].
To assess the accuracy of CT scanning measurements of femoral anteversion, 35 adult dried femora were studied by CT scan and direct measurement. The angle of the femoral neck was measured directly and the angle of anteversion by photography and by CT scanning. The accuracy of the CT scanning measurement was between 3 degrees and 4 degrees, which is consistent with other published findings. There was no significant difference between photographic and CT scanning measurements. The accuracy and reliability of the method does not alter if there is coxa valga or an increased angle of anteversion. The determination of the axis of the femoral neck remains the most difficult feature, as in other techniques of assessment.
