MRI scan after surgery using titanium screws
« on: November 13, 2008, 12:40:00 AM »
After ACl and MCL repairs a year ago using titanium screws i am being referred for further surgery.  My consultant has requested a new mri scan but is unsure of the effect of the titanium screws.  Has anyone out there had mri with titanium??

I have - the screws show as really black and you cannot really see any structures in the tunnels but the rest is readable.

What are they looking for? If the screws are stainless steel (as they are in my other leg) then the MRI is a waste of time as they fog up the whole picture. It was also uncomfortable for me. The steel screws have been in for between 20 (first ones) and 17 years - titanium has superceded them so if yours were put in recently you will have titanium for sure!

thanks... i had surgery last september but knee still unstable so being referred for further surgery.  Injury occurred 2 years ago but after being put in plaster for 7 weeks only had 20 degree mobilility and only had repairs done after 4 MUAs and athroscopy.  After repairs have maintained 90 degree mobility but with this has come increased instability!  Not exactly sure what they are looking for but consultant was unsure as to whether MRI was ok with titanium screws (they are titanium as i have metal allergies and theres no guarantee with other screws that they dont contain nickel).  I am now being referred to another surgeon who specialises in complex knee injuries..... after 2 years. 

At least i know now that i can have the MRI as i just want to keep things moving to have surgery asap.... if it doesnt work i will just have to give up and accept that skiing etc is a thing of the past!

People shouldnt overestimate the value of the MRI in post ACL cases.
An MRI of a stretched out ACL graft looks normal.
An MRI of a vertical graft is interpreted by the uninitiated as normal.
The KT-1000  and physical examination is far more reliable in post surgical cases, especially in those case where the patient doesn't have full motion.

I also have metal in my leg and my OS told me MRI'S are useless in my case.
