I recently (3 weeks ago) underwent surgery to revise c6-7 fusion that was done in 2011. The upper screws of the DePuy titanium plate had broken inside the bone and the plate was jutting out into my neck, pressing on my esophagus and trachea. The resulting inflamation was pressing on various nerves and causing alot of pain and numbness. My surgeon has asked several times if I had been in a car wreck, or some other traumatic incident, but I've not had any accidents since the plate was first installed.
I can't imagine why these screws broke, but am happy that there wasn't any more serious damage done. I do have to admit that I'm now paranoid that something else will break in there. Has anyone had any similar experience? It's even been suggested that the device could have been defective. Any helpful hints? Thanks!
