5. Study Description
Brief Summary
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.
