Executive Summary
Zimmer Trabecular Metal hips: Patients implanted with Zimmer's highly porous Trabecular Metal monoblock hip replacement cups showed up to 41% mean bone density growth around some areas of their hip implants, compared to a 45% loss in density in some areas around titanium cups, over a mean follow-up of 7.7 years in a 17-patient study sponsored by Zimmer.
