Nonrheumatoid Inflammatory Arthroses of the Hand and Wrist.

Various inflammatory and autoimmune conditions affecting joints of the hand and wrist can present with symptoms similar to those of rheumatoid arthritis. The most common of these nonrheumatoid arthroses are psoriatic arthritis, systemic lupus erythematosus, and systemic sclerosis. Management of these and several other conditions is typically medical in nature and continues to evolve with the development of biologically targeted medications. Surgical treatment is not frequently used but can be efficacious for severe cases to alleviate symptoms and correct deformities.
