Analyses were made separately for interphalangeal and CMC-1 joints, and adjusted for age, sex, body mass index, psychosocial factors, use of analgesics and osteophytes.
Both 10 joint US protocols (assessing MCP 2-3, PIP 2-3 and CMC-1 or PIP 2-3, DIP 2-3 and CMC-1 joints) performed better than conventional radiography, by identifying osteophytes in an additional 25.6% and 23.9% of patients, respectively.
