Intra-articular bone density

1. Rheumatoid arthritis is associated with intra-articular bone density in humans (total 263.0 ± 44.8; trabecular 171.2 ± 35.6; cortical 610.2 ± 62.0).

   “RA patients showed significant (p < 0.001) loss of intra-articular total (263.0 ± 44.8), trabecular (171.2 ± 35.6), and cortical bone (610.2 ± 62.0)”

1. Age is associated with intra-articular bone density in humans (297–312 mg HA/cm3 until age 60; 237.5 ± 44.3 thereafter).

   “but decreased significantly (p < 0.001) in women thereafter (237.5 ± 44.3) with loss of both cortical and trabecular bone.”
