Groin pain after metal-on-metal hip resurfacing prosthesis
Total hip replacement continues to be a widely successful operation, but persistent groin pain following a metal-on-metal hip resurfacing remains a problem for some patients. The concern regarding the safety and efficacy of metal-on-metal total hip replacements has been rising. We present the case of a 47-year-old man with groin pain after metal-on-metal hip resurfacing. We observed high metal ...
متن کاملEarly clinical failure of the ACCIS® metal on metal hip arthroplasty system - A metal on metal hip with a difference.
The ACCIS hip system has been marketed with a unique bearing surface which the manufacturers claim to reduce wear below the level of other MoM bearings and consequently less metal ion release. The cobalt-chrome-molybdenum alloy is heat treated to reduce the number and size of block carbides and the surface is modified with titanium-niobium-nitride to create a ceramic-like surface. We present ou...
متن کاملThe painful metal-on-metal hip resurfacing.
We carried out metal artefact-reduction MRI, three-dimensional CT measurement of the position of the component and inductively-coupled plasma mass spectrometry analysis of cobalt and chromium levels in whole blood on 26 patients with unexplained pain following metal-on-metal resurfacing arthroplasty. MRI showed periprosthetic lesions around 16 hips, with 14 collections of fluid and two soft-tis...
متن کاملMetal-on-metal hip resurfacing: a consensus from the Advanced Hip Resurfacing Course, Ghent, June 2009.
We report the consensus of surgical opinions of an international faculty of expert metal-on-metal hip resurfacing surgeons, with a combined experience of over 18,000 cases, covering required experience, indications, surgical technique, rehabilitation and the management of problematic cases.
متن کاملImplant failure in bilateral metal-on-metal hip resurfacing arthroplasties: a clinical and pathological study
Metal-on-metal hip resurfacing arthroplasties (MoMHRAs) have a high failure rate due to pseudotumour formation. It is not certain whether pseudotumours in bilateral MoMHRAs form on the basis of an adverse reaction to metal debris (ARMD) that is entirely due to a local innate and adaptive immune response to Cobalt-Chrome (Co-Cr) wear particles. To determine if there is a systemic component to AR...
