With ultrasound, substantial to excellent intra-reader reliability was found for inflammatory features of hand OA. Inter-reader reliability was moderate, but overall high close agreement between readers suggest that better reliability is achievable after further training. Assessment of osteophytes in the STT joint and cartilage in the PIP joints achieved less good reliability and the latter is not endorsed.
