There are success stories. I consider myself one of those. I am approaching 6 years post-op from a 1st rib resection. It was the result of an MVA but I was predisposed to the problem with an abnormal 1st rib. The attrophed had and forearm muscles recovered and my post-surgery EMG/NCV show evidence of nerve regrowth. I think they called it polyphasia. I periodically check out the forums because I have spine problems and vascular TOS on the opposite side due to a cervical rib but I'm avoiding surgery until the symptoms get severe enough.
