Wear Measurements of E-Poly in an Uncemented THA With Either 32 or 36 mm Caput of Ceramics.

Summary

The aim of the study is to compare polyethylene wear in an uncemented total hip prosthesis with 3rd. generation highly cross-linked polyethylene with a 32 mm ceramic femoral head compared to a 36 mm ceramic head. Using X-ray, RSA and DEXA. The polyethylene to be used is E-Poly (Biomet). The H0 hypothesis is that there is no difference with regard to polyethylene wear and bone loss between the two groups.

Detailed description

Uncemented THA, 32 mm or 36 mm caput of ceramics, E-Poly inserts. Measure wear with RSA, X-Ray and bone mineral density with DEXA.
