Open Access Abstract The aim of this 2-year longitudinal observational study was to explore hand bone loss as a disease outcome measure in established rheumatoid arthritis RA . A cohort of 215 patients with RA 170 women and 45 men aged 20-70 years were recruited from the Oslo RA registry and studied for changes in hand bone mass during a 2-year follow-up. Digital X-ray radiogrammetry DXR was used to measure cortical hand bone mineral density BMD and metacarpal cortical index whereas dual-energy X-ray absorptiometry DXA was used to assess whole hand BMD which measures total cortical and trabecular bone. .
