In Best of Both World's Picard is shown to have a prosthetic arm.
Was his real arm removed, or was the prosthetic simply ontop of his real arm/hand? If his hand/arm was removed, does he then have a fake hand/arm for the rest of the series?
NOTE This is not a dupe, the other question does not answer what happened to his arm, and looking at the answer I received they clearly did have an idea to replace his arm.
