Second-Generation Versus First-Generation Cementless Tapered Wedge Femoral Stems.
Clinical outcomes of a new second-generation proximally coated, tapered wedge cementless stem were compared with those of its predecessor regarding (1) all-cause implant survivorship; (2) objective and subjective outcomes; (3) complications; and (4) radiographic features. Patients who underwent a primary total hip arthroplasty with the second-generation stem (68 hips) were compared with those w...
متن کاملEffects of micro-arc oxidation coating on outcomes of a cementless grit-blasted tapered-wedge stem in total hip arthroplasty.
To evaluate the effects of micro-arc oxidation (MAO) coating on the outcomes of a grit-blasted tapered-wedge stem in total hip arthroplasty (THA), we performed a retrospective review of 141 THAs using MAO coated stem for a minimum of 5years and compared them to 219 THAs using the same geometry stem without MAO coating. Harris hip score improved from 43.7 points preoperatively to 93.9 points pos...
متن کاملCORR Insights®: Is Model-based Radiostereometric Analysis Suitable for Clinical Trials of a Cementless Tapered Wedge Femoral Stem?
A s populations increase in size, and as total hip arthroplasty is increasingly performed in younger patients, the burden on healthcare systems grows. Implant survivorship beyond two decades is becoming an imperative. Unfortunately, many hip implants have been introduced—often as minor modifications of a successful design—only to fail catastrophically. Joint registries pioneered by the Scandina...
متن کاملEffect of femoral canal shape on mechanical stress distribution and adaptive bone remodelling around a cementless tapered-wedge stem
OBJECTIVES In total hip arthroplasty (THA), the cementless, tapered-wedge stem design contributes to achieving initial stability and providing optimal load transfer in the proximal femur. However, loading conditions on the femur following THA are also influenced by femoral structure. Therefore, we determined the effects of tapered-wedge stems on the load distribution of the femur using subject-...
متن کاملThe Use of a Cementless Tapered Stem in Young Patients Affected of Secondary Hip Arthritis
Introduction: The Wagner cone stem was designed for uncemented hip arthroplasty in difficult proximal femoral conditions or femoral deformities. The most common indications for the use of this stem are secondary hip arthritis due to developmental hip dysplasia, septic arthritis or congenital malformations. We present a case series of patients that underwent hip arthroplasty with the use of a Wa...
