Materialise aMace

Personalized acetabular implants

Up to 27% of hip revisions are re-revisions due to a suboptimal fixation and biomechanical reconstruction1. Re-revisions are three times more likely to fail compared to the first revision2. The aMace personalized implant is designed to break this revision cycle.
