Objectives: The aim of this study was to evaluate the appropriate position of the forearm for measuring the BMD (Bone Mineral Density).
Material & Methods: CT scanning was performed in 21 men to determine the appropriate position for the forearm. Twenty one healthy volunteers who were without any history of operations, anomalies or trauma were enrolled. CT scanning was used to evaluate the cross sectional structures and the rotation angle on the horizontal plane of the distal radius. The rotation angle was measured by the m-view program on the PACS monitor. The DXA was used for measuring 20 dried radii of cadaveric specimens in pronation and supination with 3°, 5°, 7° and 10° of rotation respectively, including a neutral position (0°) to evaluate the changes of BMD according to the rotation.
Results: The mean rotation angle of the distal radius on the CT scan was 7° of supination (76%, n=16), 3.3° of pronation (15%, n=3), and 0° at the neutral position (9%, n=2), respectively. The total average rotation angle in the 21 people was 5.2° of supination. In the cadaveric study, the BMD of the distal radius was different according to the rotational angles. The lowest BMD was obtained in 1.4° of pronation.
Conclusion: In the case of the measuring of the BMD in the forearm in a neutral position, the rotational angle of the distal radius is close to supination. Therefore, pronation is needed for the constant measurement of BMD in the forearm. We recommend measuring the lowest BMD of the distal radius at about five degrees of pronation.
