Part of me wants them to decide to just do the surgery now. My nightmare for this is that they wait a couple more months before pulling out the blades. This shouldn't be that hard to diagnose. There should be lots of data on how injuries like this heal and what to expect. If this type of injury has any tendency to linger if surgery is not performed than he should get cut now. If they do perform surgery in a couple of months than somebody(s) need to look for other lines of work.
