Guest zachman17 Posted October 12, 2008 Share Posted October 12, 2008 For those doing joints, are you guys using a lot of metal on metal bearing surfaces? The surgeons I work with all tend to stay away from metal on metal surfaces due to the theoretical consequences of increased metal ion generation. some guys even avoid modularity because you get increased metal ion release between the stem/neck articulation. we've also seen several 'psuedotumors' in people with metal on metal surfaces.

GatorKev Posted October 13, 2008 Share Posted October 13, 2008 We rarely use metal on metal for THA. We do a lot of resurfacings which are metal on metal. Our bearing surface is either cobalt chrome,or cermaic on highly crosslinked polyethylene. We do not use metal on metal because of the metal ion risk.

1ORTHOPA Posted October 14, 2008 Share Posted October 14, 2008 We never use metal on metal on any of our total joints. Link to comment Share on other sites More sharing options...
Razorback Posted October 16, 2008 Share Posted October 16, 2008 It is use very rarely in our clinic only in cases of young patients. Most of these have AVN. Haven't seen any adverse problems, but it is a very small population (maybe 3-4 patients). Link to comment Share on other sites More sharing options...

Guest justin45nwcc Posted October 19, 2008 Share Posted October 19, 2008 We do a lot of metal on metal hips, probably 2-3 a week. I have not seen any adverse effects from any of those but we did just have a femoral neck fracture on a resurfacing patient and had to convert it to a total.

Nakasoner Posted May 5, 2013 Share Posted May 5, 2013 We use the Stryker Accolade and do not use MoM. We have seen several patients who have had older MoM done elsewhere with problems with pseudotumors and elevated serum metal ion levels. Link to comment Share on other sites More sharing options...

shoe72 Posted May 6, 2013 Share Posted May 6, 2013 6 years ago we did some MOM hips...a few of them have washed ashore needing revisions. Terrible synovitis, bone erosion, etc in a few. Some others, no issues and they are happy with the hip. Did them for about 12-18 months, then stopped due to potential issues. Link to comment Share on other sites More sharing options...

Nakasoner Posted July 1, 2013 Share Posted July 1, 2013 check serum chromium and cobalt levels. If elevated, get Ultrasound. If +fluid, aspirate. Link to comment Share on other sites More sharing options...
