Radiological changes in rheumatoid arthritis patients at a teaching hospital in Saudi Arabia

The frequency of radiological changes of the hands and the feet were investigated in a well-definedhospital population of patients with rheumatoid arthritis in Jeddah, Saudi Arabia. A total of 57 patients who fulfilled the American College of Rheumatology 1987 criteria for the diagnosis of rheumatoid arthritis were randomly chosen from the rheumatology outpatient clinic at King AbdulAziz University Hospital. Erosions were seen in 60% of the patients and periarticular osteopenia in 34%; deformity and soft tissue swelling were present in 26% and 14% of patients respectively. The proportion with erosions is lower than data reported from Western European and North American populations but higher than previous data from the Central region of Saudi Arabia.
