Periprosthetic Bone Remodeling Around Uncemented Components in Total Hip Arthroplasty

NCT01319227 · Status: UNKNOWN · Phase: NA · Type: INTERVENTIONAL · Enrollment: 51

Last updated 2016-08-30

No results posted yet for this study

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.
