When I was a kid, I fell on my wrist. It healed up badly and formed a lot of calcium deposits around the bones. I couldn't bend my wrist backwards more than a couple degrees and it was painful. Went to a PT who used ultrasound treatments and stretching to break down the deposits, which freed my wrist up.
This was in the 1980's.
