Is it possible to get a bone spur that encroaches from the edges of the artificial acetabulum? Curious.

I think you mentioned in another post that you had an xray done.  I find it a good idea to mention to the radiologist doctor my concerns, usually I speak to the techs to observe the xrays and mention my issues, they don't say much because they can't, but from their comments I often get enough color and if I feel I need to I wait for the radiologist.

Last xray I mentioned I had a bone graft, they were wondering what that was in the xray.   

Usually the radiologist doctor does a report and if you speak with them about your issues, they should be able to point out conditions that may be concerning.
