The bone mineral density（BMD）of the proximal region of femur specimens was measured by dual-energy X-ray absorptiometry （DXA）.BMD measurement of proximal femur by DXA was influenced according to the depth of water by way of the body thickness. The BMD of the Ward’s triangle，and then the trochanteric area was significantly lower detected than the femoral neck through the depth of water. Notable error occured at 28 cm or more depth of water. The BMD of the femoral neck was not almost affected by the position of the hip from neutral to internal rotation. The position from neutral to external rotation of the hips is desirable as the limb position for DXA. The BMD of femoral neck is thought to be appropriate for the diagnosis of osteoporosis and detection of a risk factor of femoral neck fracture.
