Unfortunately, it looks like if I do anything it will be a revision. It seems the doctor didn’t take into account that I had osteopenia and used the implant where the bone was supposed to attach to the implant. Apparently the extra space was caused by the implant sinking into the bone so the doctor doesn’t feel like the spacer will correct the instability. Also, the recovery is the same as an entire replacement. She feels replacing it with an implant that is attached with bone cement will correct things.
