I made my last official visit to the orthopedic doctor today, whereby he declared my arm has successfully healed, as you can see by the x-ray (click for a closer view).
You can still see the break lines, but what's harder to see is where the bone has filled in, and my doctor assures me it has "bridged" in where needed. The pins are staying in, which is all right by me.
Pain? None. Aches? Only when shouldering a musket for a long time -- and that's true for the other arm.
God is Great.
Thank you all once again for all of your prayers and kind words.
