I am looking for the title of a shorty story at least 10 years old.
An astronaut crashes on an asteroid or a very small planet and is paralyzed by a broken neck.
He makes contact with a member of a race of small telepathic insectoids and he helps the tribe thrive by teaching them technology (specifically I remember he told them to spread his waste where they grow their food crops to increase the yield).
There was a part where another tribe tried to capture him and he somehow moved his body to crush a number of them.
I may be confusing two stories but I think the ending has two people finding the grave marker the insects had constructed for the astronaut and wondering about it (I think it was just a big piece of metal without an engraving).
if it helps at all I think it was in an orbit or analog anthology book
