Bone mineral density (BMD) in 35 female patients with rheumatoid arthritis (RA) and 63 female patients with non-RA was measured by dual energy X-ray absorptiometry (DXA). The two groups were aged-matched, and a comparison was carried out between the BMD of their total body, lumbar spine, and femur (neck, Ward's triangle and trochanter). Twenty patients were diagnosed as having osteoporosis on plain X-p of their lumbar spine. BMD of the lumbar spine and ward's triangle was significantly decreased in RA patients with osteoporosis. BMD of the lumbar spine, Ward's triangle, and neck were significantly decreased in non-RA patients with osteoporosis. BMD loss late in the post menopausal period of RA was normal, and inactivity and other factors related to the development of osteoporosis with RA.
