To the Editor.
—Dr Meuleman's review article "Beliefs About Osteoporosis: A Critical Appraisal,"1 is useful. I trust that the following comments regarding this subject and his article are also useful.Measurements of bone mineral density utilizing dual photon absorptiometry are very precise (reproducible). This methodology (unlike all other techniques) permits repetitive accurate assessment of bone mineral density in the lumbar spine and the femoral neck. Therefore, it permits assessment of the effectiveness of a therapeutic strategy in the osteoporotic patient. It permits more rational decisions regarding the use of female gonadal hormones, fluorides, and calcitonin. This review (like most of our literature) focuses primarily on the women at risk. Males also develop osteoporosis and experience important fractures (of the femoral neck) as a consequence. Prediction of nonviolent fracture risk will not be clarified until longitudinal data of the frequency of these fractures is correlated with bone mineral density measurements
