Hi GoBlue,
I think it depends on what they mean by "local". Usually local means the soft tissue of the area they are going in but maybe they mean more than this. Regional means they do an actual block of the nerve or nerves supplying the area. For example, when the medial ankle is blocked they often block both the posterior tibial nerve and the saphenous. The dorsum of the foot would be saphenous and peroneal. It totally depends on where they go in. Some docs block regionally at the ankle some go above the knee. Blocks do have potential risk, so perhaps they are thinking this a quick procedure and local is all that is needed.
Questions, Have they said how much time they need? Is an anesthesiologist going to be there?
PS....Don't be fearful of tourniquet if they use one. It greatly increases visibility and hemostasis in the surgical field. Not a bad thing.
