Periprosthetic Bone Remodeling Around Uncemented Components in Total Hip Arthroplasty

Periprosthetic Bone Remodeling Around Two Different Types of Uncemented Femoral Stems and Two Uncemented Acetabular Components in Total Hip Arthroplasty

Summary

This is a randomized clinical trial comparing two different uncemented femoral stems and two different uncemented sockets using Dual-energy x-ray absorptiometry, Radiostereometry and clinical evaluation. Hypothesis: 1. A short uncemented stem gives less periprosthetic bone resorption in the proximal femur than a conventional uncemented stem. 2. An uncemented acetabular component with a backside of three-dimensional Titanium porous construct gives less periprosthetic bone resorption than a backside covered with a conventional porous coating with Titanium-beads and a hydroxy-apatite layer.

Detailed description

Consecutive patients 40-70 years old who are being planned for Total Hip Arthroplasty (THA) will be eligible for inclusion in the study. Periprosthetic bone remodeling, migration of the components and clinical scores will be recorded prospectively.
