Osteoporosis is a recongnize complication of rheumatoid arthritis. Osteoporosis can affect the final outcome of any joint replacement surgery, if not diagnose and treated early.
Objectives We have evaluated prevalence of post menopausal osteoporosis in Post menopausal female patients with Rheumatoid disorder awaiting for lower limb joint replacement surgery.
Methods 87 patients, after satisfying inclusion and exclusion criterias, were enrolled in our study and bone mineral density was assessed by Dual Energy X-ray Absorptiometry (DEXA) scan and classified as per World Health Organisation classification. The logistic regression and multivariate analysis were used to find out the risk factors associated with osteoporosis in post menopausal female patients with rheumatoid arthritis.
Results The overall rate of osteoporosis at any site was 39% and a further 41% of patients found to osteopaenic as per World Health Organization criteria. Significant risk factors associated with post menopausal osteoporosis in our study are Age, Body mass index, Onset of arthritis at younger age, History of prior fracture, Long term steroid intake and Co-morbidities.
Conclusions High prevalence of osteoporosis found in our study suggests, BMD testing in post menopausal women should be made in patient undergoing arthroplasty surgery, to achieve successful functional outcome of arthroplasty surgery.
