the simplest explanation is usually correct.

We know Cinder had to replace the bug because Salem said as much, so if the Geist arm is a replacement for the bug, it likely means Salem found a way to implant an entire Geist into Cinder's body that she controls just like the bug, that makes the more important question "are there any living cells within the arm?"
