AB0884 Prevalence of ultrasonographic gout specific signs of hand and fingers joints

Objectives To evaluate the prevalence of ultrasonographic gout specific signs of hand and fingers joints. Methods This is a cross-sectional study which includes 15 patients with chronic gout, defined according to the American College of Rheumatology criteria (ACR 1977). Ultrasound (US) examination was performed using a high-frequency linear probe (Toshiba Xario®, frequency (8–14 MHz)) in B mode. 540 articular sites were studied at their dorsal surface. The ultrasound has objectified the presence of two signs: hyperechoic band over the superficial margin of the articular cartilage described as a double contour (DC) and the tophaceous deposits at the joint cavity. Results The mean age at onset was 54.7±12,6 years, and the median diagnosis duration was 0 (0.3) years). The results of the US examination are summarized in Table 1. Conclusions This study showed a predilection for the gout specific ultrasound signs (DC and tophaceous deposits) of the wrist and MCP joints. The contribution of musculoskeletal ultrasound seems to be very interesting to objectify the presence of gout specific signs in the hand and fingers joints. Disclosure of Interest None declared
