The Pony went back to the doctor today for his broken arm. He has been in a splint for the past two weeks, which is like a half cast and two elastic wraps to keep that arm and elbow immobile. After three more x-rays, the orthopedist determined that no break is evident, and released The Pony's arm and The Pony with no restrictions. The doctor said it might have been a sprain instead of a hairline fracture, but that the treatment would have been the same: a splint.
The Pony is prancing with glee. He now has two good arms for carrying his laptop and playing his computer games and unwrapping Christmas gifts and helping me with Devil's Playground bounty. Plus, he can take a shower instead of a bath, can button his pants again, and wear a coat, and play his trombone.
Aside from intermittent mild dull pain that he says goes away if he waits long enough, The Pony is as good as new.
We are all relieved. Including the #1 son, who uses The Pony as a personal servant.
