Unfortunately we are a highly compartmentalized society - not only in medicine, but all other aspects of life. For example, the floors being redone at my daughter's house - one guy tears out the old floor, another guy comes in & makes sure the subfloor is sturdy & level, a third guy lays the new floor, a fourth comes in & puts wood putty in any holes/cracks, does the final sanding & cleaning, then varnishes...then we reinstall the baseboards and shoe molding. That's in addition to the guy who bid the job... that's 6 people! 30 years ago the same company sent 2 guys to do the whole job, with 5 times as much square footage, in our house. (And each arrived in his own truck.)

Or the plumber who required my daughter (in a cast) to remove the access panel on her tub because it wasn't just a factory one, but a handmade one, so he could look at the pipes.

So if the trades and crafts are that specialized, is it any wonder medicine is as well. When I called for an ortho eval appointment for my husband, the scheduler amazed me - "It says here he does shoulders, elbows and wrists, I have to call his PA and see if he does forearms too" Of course he does! That's what attaches one to the other.

Add to that the fear by the subsequent doc that he may be blamed or sued if he can't fix the original problem. I'm so fortunate my ortho has enough confidence to do "do overs."
