Make a bit of sawdust. pack some in around the hinge point, drill a small hole to the hinge point, or evan make a slightly larger hole and pack it full of sawdust. Then give er a couple drops of ca. in the new hole and it should be as good as new.
My new way of keeping glue out of the hinge is to wrap a thin strip of blenderm hinge tape around the joint before glueing. Then remove it.
