The atlas includes reference images of each grade of each feature that is assessed in TOMS (synovitis grade 0–3, subchondral bone defects grade 0–3, osteophytes grade 0–3, cartilage assessment grade 0–3, subluxation and bone marrow lesions grade 0–3) in the first carpometacarpal and scapho-trapezio-trapezoid joint. The presented reference images can be used to guide scoring of thumb base MRIs in patients with hand osteoarthritis according to the OMERACT TOMS. ER -
