Re: L5S1 posterior interbody fusion post 10 years
It really depends and they may not know until they are in. They may clean out the old fusion, add bmp, restabilize with screws, plates, rods, or larger rods.
I have a fusion from 1982 and they told me this is common after 10 to 15 years. Fortunately I have not had this issue but I have had problems with above the fusion - new levels.
Take care and keep us posted.
