Radiographic Migration Analysis of the Insignia Hip Stem

The purpose of this study is to assess the migration pattern of the Insignia hip stem using radiostereometric analysis (RSA for short) and computed tomography (CT). Only patients with degenerative joint disease requiring primary total hip replacement will be asked to participate. The other purpose is to assess if there are any differences between the gold-standard RSA-measured migration and CT-RSA-measured migration. The clinical outcomes will be measured using joint function and patient satisfaction questionnaires. Approximately thirty patients will be enrolled onto the study.
