The hand and wrist are commonly involved in rheumatic conditions, particularly rheumatoid arthritis and other systemic connective tissue diseases. With spondyloarthritis, hand and wrist involvement frequently occurs in psoriatic arthritis but generally does not occur in the remaining subtypes. The hand and wrist may also be affected in various metabolic and endocrine diseases, but these lie beyond the scope of this review.Radiographs may demonstrate the presence of joint space narrowing, bone loss, cysts and erosions, malalignments, and osteolysis. They may also show regions of soft tissue swelling or thinning, and detect calcifications. Ultrasonography and magnetic resonance imaging (MRI) enable evaluation of the soft tissues, particularly the synovium, tenosynovium, and tendons. Furthermore, erosions are better demonstrated than on radiographs. MRI allows evaluation of periarticular bone marrow edema.This article discusses typical imaging features of the hand and wrist in rheumatologic conditions including the advantages and limitations of the various methods.
