If a person had been paying attention, and looking backward frequently, they might be able to backtrack either to where they knew where they were, or maybe at least to an open area where fires, smoke, mirror, on-ground messages might be effective. IF it was likely anyone was looking for you.

If you were lost but still knew which direction a paved road was, you could try heading in that direction, if there was no likelihood of cliffs, canyons or strong rivers in between.

Breaking your leg in deep woods alone considerably increases your chance of attracting flies and signaling with decomposition odor to someone. Or something.
