Hand Osteoarthritis Patients Have Increased Bone Mineral Density

Several studies have been performed on the relationship between hip or knee osteoarthritis and increased bone mineral density (BMD), but there have been few that have addressed the relationship in hand osteoarthritis.
A study was published last month in the Annals of Rheumatic Diseases that does just that – compare the BMD or hand osteoarthritis patients to rheumatoid arthritis (RA) patients and controls.
190 women, aged 50 to 80 years, with hand osteoarthritis, 194 with rheumatoid arthritis and 122 controls were involved in this cross-sectional study. The participants had BMD measurements of the hip, femoral neck and lumbar spine using dual-energy X-ray absorptiometry. Other relevant information was obtained through interviews, questionnaires, and clinical joint examination.
The researchers found that patients with hand osteoarthritis had significantly higher BMD levels than the RA or control groups.
They also found the there was no significant difference in the frequency of osteoporosis, a bone disease resulting in loss of BMD, between the osteoarthritis and control groups. However, the frequency of osteoporosis in RA patients was significantly higher than in the osteoarthritis patients.
The researchers did not find any link between the BMD levels and the duration or severity of the disease symptoms.
The study was conducted by Dr. I. K. Haugen and colleagues from Diakonhjemmet Hospital in Oslo, Norway.
