Comparison of trabecular metal cups and titanium fiber-mesh cups in primary hip arthroplasty
BACKGROUND Trabecular metal has shown promising results in experimental studies of bone ingrowth. Several clinical studies support these results. However, until now, no randomized clinical radiostereometric analysis (RSA) studies have been published. In this randomized RSA trial, we compared a new acetabular cup with a surface made of tantalum trabecular metal and a cup with a titanium fiber-me...
متن کامل• Porous Titanium Particles in Cemented Impaction Grafting Hip Revision Arthroplasty: Pre-Clinical Results
Introduction: Bone impaction grafting (BIG) is a surgical technique for the restoration of bone stock loss in revision total hip arthroplasty (rTHA) by impaction of allograft bone particles (BoP) into the bony defect. BoP are considered to be the gold standard, although many alternative materials have been developed, most of them being ceramic based. Important properties of these synthetic mate...
متن کاملCementless modular hip revision arthroplasty with the MRP titanium stem
As the number of primary THRs of younger patients with high physical demands increases, the amount of revision operations also grows. Bone loss with severe osteolysis, joint instability, function of pelvitrochanteric muscles, leg length discrepancy, a proper antetorsion angle, cement mantles, periprosthetic fractures, or infections are problems to be considered in revision arthroplasties of the...
متن کاملAcetabular revision in total hip arthroplasty with tantalum augmentation and lyophilized bovine xenograft☆
OBJECTIVE To evaluate a mixed technique of acetabular reconstruction, which uses trabecular metal in the form of tantalum augments associated with lyophilized bovine xenograft. METHODS Fifteen patients were evaluated prospectively, who underwent acetabular reconstruction with impacted lyophilized bovine xenograft associated with the use of tantalum augments. The main outcome was the failure o...
متن کاملEffects of hydroxyapatite coating of cups used in hip revision arthroplasty
BACKGROUND AND PURPOSE Coating of acetabular revision implants with hydroxyapatite (HA) has been proposed to improve ingrowth and stability. We investigated whether HA coating of revision cups can reduce the risk of any subsequent re-revision. METHODS We studied uncemented cups either with or without HA coating that were used at a primary acetabular revision and registered in the Swedish Hip ...
