disclaimer, i dont even know if i need this surgery yet. i am still waiting for a block

but does anyone know off the top of their head if there are different approaches to this operation?
what kinds of questions i should ask beforehand?
is it a kind of surgery you would need to travel to get done or could i get it done locally (im in atlanta)?
is it pretty obvious to see if your brachial plexus is scared or stuck somehow while youre cut open? or can only a select few see this?
