To assess the presence of generalized osteoporosis in rheumatoid arthritis (RA), we measured bone mineral density in various portions of the bodies of 59 patients with RA and 30 healthy subjects by dual energy x-ray absorptiometry. Severe bone loss from the extremities was observed in the RA patients, while loss from the trunk was modest. However, bone loss from both the extremities and the trunk was increased in patients with progressive RA. In the extremities, more bone loss was observed in the distal areas than the proximal ones.
