A novel technique for the removal of well-fixed, porous-coated acetabular components with spike fixation.

摘要

The removal of well-fixed, porous-coated acetabular components at the time of revision total hip arthroplasty can be challenging. The presence of spike fixation can increase the difficulty of removing an acetabular component because traditional methods of component removal, such as the use of curved gouges, may not be possible. We report a novel technique for the removal of well-fixed, porous-coated acetabular components with adjunctive spike fixation. This technique uses an overlay template that targets the spikes for removal with a high-speed, carbide-tipped bur.
