Hi Darshin
Just the once ... and never again

Does that answer the question?!
I had very bad swelling in my right wrist which was thought to be partly due to a joint infection. I believe arthrocentesis in RA is done only rarely because of the complex nature of the bone structure of the wrist and the difficulty of getting into the intercarpal spaces. I think it is more often performed for diagnostic purposes.
Steroid injection into the wrist has a good success rate, I understand, although it can be of a very temporary nature. Wrists showing long term damage often require fusing or replacement.
