Objectives-To evaluate the impact of rheumatoid arthritis (RA) on the incid
ence of hip fractures.
Methods-All patients with acute hip fractures admitted to Jyvaskyla Central
Hospital in 1991-93 (n=517) were selected from the hospital discharge regi
ster. Medical records of these patients were studied retrospectively for RA
fulfilling the American Rheumatism Association criteria. The prevalence of
RA in patients with hip fractures was compared with the prevalence rates o
f RA obtained from the nearby city of Tampere.
Results-29 (5.6%; 95% CI 3.8 to 8.0) of the patients with hip fracture in J
yvaskyla Central Hospital had RA. The age and sex adjusted risk of hip frac
tures was increased by RA (risk ratio 3.26; 95% CI 2.26 to 4.70).
Conclusions-Patients with RA are at increased risk of osteoporotic hip frac
tures.
