Greetings James Thomas.
As one who HAS had surgery to fix broken bone situation, I would advise extreme caution, as ALL surgery causes a degree of scar tissue formation that will be IN ADDITION, to any already present from your injury. Unless the surgeon could prove to me that this surgery was of immediate importance, I would rely on therapy first ! Of course, it depends on how much pain or discomfort you are experiencing. I have already had to have surgery, to remove the scar tissue build up from the original surgery. I had no choice in the matter of the original surgery, as the bone in my wrist actually died, and was necrotic. However, the scar tissue caused me to experience pain within a few years after the original surgery, and also caused carpal tunnel syndrome. I couldn't stand the numbness, tingling and burning sensation, plus I dropped everything I grasped with my left hand for months before the surgery. The last surgery has been 20 years ago, but within 5 years I had more scar tissue build up, which created a large "knot" on top of my left wrist, which limits range of motion. So, despite what doctors will say(to make money in the end) surgery should be the final option when it is possible, and physical therapy can often work wonders. A friend of mine had arthoscopic rotator cuff surgery which did not bring relief, but made pain worse. He then opted for major surgery instead of 12 weeks physical therapy. Three more surgeries later, he can no longer lift arms above perpendicular to floor, and can no longer restore and hot rod vintage Cheyy's, which he existed for. He has slid into depression, and is on disability for THAT. He does nothing anymore but watch T.V. I'm a liberal at heart, but when it comes to "the knife" I am most definitely a conservative in my approach.
What ever you decide, good luck, and may God speed your recovery.
Sincerely tonequester.
