My 2 cents only, any loose screw that was in function for a while, I almost always order a new one because I don't want
to risk a broken screw. If not replace with new one straight away, will ask pt to come back to replace with new one.
A lot less headache than if one breaks in the implant later and did not offer to replace with new one. And try to identify
a reason it got loose in the first place.
