Roberto, thanks for posting.  I like to see the fusion successes.  Too many patients looking for ADR really need a fusion and don't understand that a fusion may represent their best hope.  I hope to hear that your mother continues to do well.  Please keep us posted.

PS.  I deleted your duplicate post but will put the larger versions of your pictures here.  They really show the fusion and the growing fusion mass.  The dots on the a/p (front/back) view are radiographic markers put into the cage because it's made of radiolucent materials.
