Final answer:
The question discusses deformities associated with Systemic Lupus Erythematosus, including metacarpophalangeal joint dislocation, swan-neck deformities of the fingers, and a boutonniere configuration of the thumbs.
Explanation:
The student's question pertains to SLE, or Systemic Lupus Erythematosus, a chronic autoimmune disease that can affect any part of the body. It seems to mention some common deformities commonly seen in patients with this disease. The metacarpophalangeal joints are located in the hand where the fingers and the hand meet, and dislocation of these can be a severe complication of SLE. Swan-neck deformities refer to a specific appearance of the fingers, where the base and top most joint of a finger are bent, but the middle joint is extended. The boutonniere configuration is a deformity where the thumb takes on a flexed position, looking like a buttonhole ('boutonniere' in French).
