From _Art for Eternity_, Fazzini, Romano and Cody, page 157
djed-pillar "An Egyptian hieroglyph, probably a manifestation of part of the spinal cord, that was a written form of the word for 'stability'. It was a commonly employed symbol in religious iconography."

From _Reading Egyptian Art_, Wilkinson

As an amulet, the djed was more likely to be used for funerary purposes, "to assure stability for the deceased." It was "common for a string of about a dozen pillars to be placed across the belly of the mummy, just opposite the lower vertebrae. "(_Ancient Egyptian Magic_), Bob Brier, page 154)

On my visit to the Brooklyn Museum in 2012, I captured another djed amulet:
