Revision, Cup only? Save resurfacing?
Is it possible to save your resurfacing device if the femoral component is place correctly and only revise the cup?

Cup breakout can easily be addressed by cup only revision. I used to get this with the Corin device I used and I've successfully carried out several cup only revisions over the past 20 years. A large inventory needs to be available for revision surgery including thicker cups, dysplasia cups and THA cups with a BHR (or whatever other resurfacing device has been used) compatible liner. Much better to get on and revise the patients hip than mess around with MRI's & metal ion tests. (Vicky's comment: Derek is referring to devices other than recalled defective devices where the cup has slipped, patients should check with him on a case by case basis, I can get you in touch with him if you are in such a situation) Delay will only serve to guarantee edge wear of the loose vertical cup.
With the BHR in a series of 3205 cases until Dec 2010, I've had 2 late cup loosening 9 & 12 years post-op- no early breakouts. Early breakout with the BHR cup is either caused by poor surgery with a poor primary fix or too early return to high activity before cup osseo-integration happens.
