What deformities are associated with rheumatoid arthritis?

Boutonniere deformities are associated with rheumatoid arthritis due to the effects of this autoimmune condition on the joints and connective tissues. In rheumatoid arthritis, inflammation can lead to the weakening and destruction of the tendons that stabilize the fingers. This results in a characteristic deformity where the middle joint of a finger is flexed while the finger itself remains extended at the outer joint. As the condition progresses, the ongoing inflammation and joint damage cause alterations in the positioning of the fingers, leading to functional limitations and affecting the individual's ability to grasp and manipulate objects.

The presence of boutonniere deformities is significant in the context of rheumatoid arthritis because they reflect long-term joint changes that can arise from chronic inflammation. Recognizing these deformities is important for nursing assessments and patient education, as they can help guide treatment to preserve function and improve the quality of life for individuals with rheumatoid arthritis.
