Have 6 screws and a plate in r foot from lisfranc fusion. Have pain and X-ray shows one screw digging a groove in neighboring bone. What options?

Painful Hardware. If the surgery was over a year ago, and the joint appears to have fused, removal of the hardware would probably be the best option. If it was fairly recent or it never fused (non-union), may need to give it some more time and/or use a bone simulator. If it is a nonunion, sometimes revision is necessary (removal of hardware and replacement with new hardware after preparing fusion site again).
Depends... It depends on how far post-op you are. If it's been long enough, have the hardware removed.
