Wow!!! You certainly did a good job. I see from the xrays that these coder two periods, the most recent being in Dec 2007. Perhaps that was after the second grafting.

To be honest I think the surgeons have done a poor job, or that the fixation is not holding. There seems to have been movement in the bones since the earlier images and the alignment is way off. Not sure how one wants to get bone union when the bones are not in a placement to encourage them joining together.

I am sorry to be so blunt and negative but if I were in your shoes I would be looking for another orthopaedic opinion asap. Have you any facility to seek treatment in another country?
