About
The purpose of this study is to compare metal surface finishes (proximal-coated titanium surface versus mid-coated titanium surface) on femoral components in hip arthroplasty.
Full description
In younger patients femoral components are most often implanted without the use of cement. A direct ingrowth of bone to the implant is crucial to the attainment of good results in those cases where cement is not employed.
The construction of a femoral implant, Versys Fiber Metal Taper®, by Zimmer includes a more extensive coating than previous femoral implants. The improved surface coating has been shown to provide these implants with better properties than those demonstrated by implants currently in general use.
Theoretically, the greater porous surface of mid-coated implants should:
The migration of femoral components will be evaluated by RSA, performing radiostereometric analyses at the Orthopaedic Center, Aarhus University Hospital. The follow-up RSA will be scheduled for week 1, as well as 3 months, 12 months and 2 years after surgery. Bone mineral density around the implanted femoral component will be examined by DEXA scan at week 1, as well as 1 year and 2 years after surgery.
