This is true but it is also true that Physician's success rates are absolute garbage. They will consider it a success if nothing goes wrong during the surgery. They will not take into account what happens after the surgery. I was written off by the doctor who did my TOS surgery and I am pretty sure they lumped me into the "success" category. So far it has been the exact opposite of success and I was way better off before the surgery. Different people scar at different rates. They will tell you that they use this polysorb surgiwrap around your nerves during the surgery to prevent scarring. They used this on me and my post op MRI still shows scarring on the nerve roots, trunks, and cords of the brachial plexus. MRIs normally don't even pick up scar tissue on the scan unless there is a significant amount meaning the polysorb surgiwrap was ineffective in my case.
