Ion Release from Metal-on-metal Hip Resurfacing Implants Does Not Differ from Standard Metal-on-metal Total Hip Replacement
STANDARD METAL-ON-METAL TOTAL HIP REPLACEMENT *Moroni A, **Savarino L, *Cadossi M, **Greco M, **Baldini N, *Giannini S * Rizzoli Orthopaedic Institute, Bologna, Italy **Laboratory for Pathophysiology of Orthopaedic Implants, Rizzoli Orthopaedic Institute, Bologna, Italy [email protected] INTRODUCTION Modern metal-on-metal (MOM) hip resurfacing has been introduced as a less invasive method of join...
متن کاملCorrosion on the acetabular liner taper from retrieved modular metal-on-metal total hip replacements.
Eight retrieved metal-on-metal total hip replacements displayed corrosion damage along the cobalt-chromium alloy liner taper junction with the Ti alloy acetabular shell. Scanning electron microscopy indicated the primary mechanism of corrosion to be grain boundary and associated crevice corrosion, which was likely accelerated through mechanical micromotion and galvanic corrosion resulting from ...
متن کاملComparison of Complications Following Revision of Metal-on-Metal Versus Metal-on-Polyethylene Total Hip Arthroplasty.
The aim of this study was to examine the clinical characteristics of patients who required revision and the rate of early complications after revision for metal-on-metal total hip arthroplasty (MOM THA) and metal-on-polyethylene total hip arthroplasty (MOP THA). Matched cohorts were selected by retrospective review from a single-center database of revision THAs for failed MOM and MOP THAs from ...
متن کاملEarly osteolysis following second-generation metal-on-metal hip replacement.
BACKGROUND Total hip arthroplasty with use of metal-on-metal bearings has been reintroduced as an alternative to the use of metal-on-polyethylene bearings because of theoretical advantages such as reduced wear and a lower prevalence of osteolysis. However, we observed early osteolysis in a cohort of patients who had been managed with second-generation metal-on-metal hip replacements and investi...
متن کاملDissociation of the S-ROM metal-backed polyethylene acetabular liner--a case report and literature review.
The authors report a case of early failure of a total hip arthroplasty with dissociation of the polyethylene liner of an S-ROM Oblong Cup*, which presented as a dislocation. Initial closed reduction of the dislocation was not possible. Open exploration of the hip revealed that the modular Poly Dial* polyethylene acetabular liner had become dislodged from the acetabular cup. The liner was revise...
