RSA-Study of Cemented Hip Prostheses With Five Different Articulations

A Prospective Randomized RSA-Study of Cemented Hip Prostheses With Five Different Articulations

The purpose of this study is to compare wear and migration of the following hip prostheses:

1. Charnley monoblock 22.2mm caput and OGEE polyethylene acetabular component
2. Spectron EF stem with Reflection polyethylene cup and 28 mm CoCr caput
3. Spectron EF stem with XLPE cup and 28 mm CoCr caput
4. Spectron EF stem with Reflection polyethylene cup and 28 mm Oxinium caput
5. Spectron EF stem with XLPE cup and 28 mm Oxinium caput

Detailed description in:
