A back injury (ruptured disk) happened to a friend at work. A microdiskectomy removed the bulge and physical therapy has him back to good health. But, the workman's comp doctor says that any time there is surgery, he has to turn in a Permanent Partial Disability (PPD) rating, even though he is now fine. Will this cause problems with 1st class physicals for the rest of his life, or can a Flight Surgeon deem him fully recovered even though the workman's comp doctor rates him with a PPD. Thank you.
