A Comparison Between Titanium Femoral Stem and Cobalt-Chromium Femoral Stem in Cemented Hip Arthroplasty

This study is ongoing, but not recruiting participants.

Sponsored by:	University of Aarhus
Information provided by:	University of Aarhus
ClinicalTrials.gov Identifier:	NCT00120952

Purpose

In this randomised study, the migration of a specific cemented titanium femoral stem will be compared with a similar cemented cobalt-chromium stem using Roentgen stereogrammetric analysis (RSA). In addition, the periprosthetic bone mineral density (BMD) will be evaluated to point out any interference from the modulus of the stem investigated.

Condition	Intervention
Osteoarthritis	Device: Bi-Metric femoral implant (titanium versus cobalt-chromium)
