I had a really bad broken my wrist. I crushed the end of the ulna and had to have pins inserted to hold thing together fr the bone to be able to grow back in. A work colleague recommended DMSO. I used a Q tip to administer it while I was in cast. My recovery astounded the bone doc both from a timeline perspective as well as a bone regrowth perspective. I made a complete recovery,especially given that I was over 50 at the time and healing naturally slows down as you age.
