Femoral anteversion measured by the Dunlap/Rippstein and Norman methods.

Measurements of femoral anteversion obtained with the Dunlap/Rippstein method in adults were compared with measurements using the Norman method. By definition, different angles are measured by the two methods. The Norman method gave angles for the femoral anteversion which were on average 12.8 degrees higher than those obtained with the Dunlap/Rippstein method, and the methods correlated poorly. It is concluded that measurements of femoral anteversion with these methods do not accurately reflect each other.
