Revision of Metal-on-metal Hip Arthroplasty with Well Fixed and Positioned Acetabular Component Using a Dual-mobility Head and Review of Literature
BACKGROUND As a consequence of use of metal-on-metal hip arthroplasties some patients have precised revision for pain or metal hipersensivity reactions among other causes. We propose to salvage monoblock acetabular component and femoral component using a dual-mobility head and perform a lower morbidity operation in young patients preserving host bone stock in cases with well fixed and positione...
متن کاملRevision of Failed Hip Resurfacing and Large Metal-on-Metal Total Hip Arthroplasty Using Dual-Mobility Components.
Revision of metal-on-metal (MoM) total hip arthroplasty (THA) or hip resurfacing is associated with high complication rates. The authors propose dual-mobility components as a surgical option and present short- to mid-term results of MoM hips revised with dual-mobility components. Eighteen consecutive hips that underwent revision of MoM THA or hip resurfacing using dual-mobility components were ...
متن کاملA Biomechanical Model of Acetabular Cup Deformation in Metal-on-Metal and Conventional Metal- Backed Component Designs
Introduction: Press-fit acetabular components are susceptible to deformation following implantation in an under-reamed socket, with excessive deformation of metal-on-metal (MOM) components potentially leading to increased torsional friction, component micromotion and implant loosening. The purpose of this study was to evaluate the effect of design and material considerations on induced deformat...
متن کاملRadiological evaluation of the metal-bone interface of a porous tantalum monoblock acetabular component.
Between January 1998 and December 1998, 82 consecutive patients (86 hips) underwent total hip arthroplasty using a trabecular metal monoblock acetabular component. All patients had a clinical and radiological follow-up evaluation at six, 12 and 24 weeks, 12 months, and then annually thereafter. On the initial post-operative radiograph 25 hips had a gap between the outer surface of the component...
متن کاملThe Trabecular Metal Monoblock acetabular component in patients with high congenital hip dislocation: a prospective study.
Between November 1997 and December 2000 we performed 27 total hip replacements in 22 patients with high congenital dislocation of the hip using porous tantalum monoblock acetabular components implanted in the true acetabular bed. Clinical and radiological evaluation was performed at regular intervals for a mean of 10.2 years (8.5 to 12). The mean Harris Hip Score improved from 48.3 (15 to 65) p...
