any neurologists/doctors out there? when a nerve is severed at the forearm...?

Question:

and surgically repaired to regenerate and provide function/feeling back into the hand. would the regenerating nerve maintain its intergrity to pick up where the original nerve signals left off?

Answers:
Not a doctor or neurologist, but I can tell you it depends on a few different things... if the nerve was cleanly cut, there's a better chance the surgeons were able to line up the nerve sheath during the repair, so the nerve has a clear path to follow to it's destination. If the injury involved a lot of trauma or stripping to the area, it could complicate things a bit.
Either way, it will take a long time to regain feeling or function - nerve grows slowly. Care for the fingers and wrist in the meantime by using appropriate splinting and maintaining full range at all joints.

Sometimes but not all the time unfortunately.
