Cobalt chromium alloy hip implant
Implants were ASR total hip replacement (acetabular implant, taper sleeve adaptor and unipolar femoral implants) performed between 2005 and 2009. This case series describes, for the first time, neuropsychiatric complications after revision where there has been cobalt and chromium toxicity.For cemented hip replacements, the clinically used stem materials include stainless steel and cobaltchromium alloys. The most often used bone cement is (PMMA). The success of a cemented hip implant depends on both a strong bonecement bonding and a stable cementprosthesis interface. cobalt chromium alloy hip implant
How can the answer be improved?
Nov 15, 2018 The cobalt levels were much higher than chromium in the cobaltchromium alloy. Blood tests also determined inflammation due to adverse local tissue responses secondary to taper corrosion. The study establishes substantial soft tissue damage from corrosion at the modular neckbody taper of a dualtaper femoral model. Jan 21, 2013 The bearing surfaces of current artificial hip replacements on the market are usually made out of polyethylene (UHMWPE), (CoCrMo) alloys, ceramics (alumina) or ceramicized metals (e. g. oxygen diffusionhardened ZrNb alloys).cobalt chromium alloy hip implant Apr 25, 2017 Different Types of Hip Replacement Implants. By Grace McClure. In most cases, the femoral stem component is built from titanium, titanium cobalt, stainless steel, cobaltchromium alloys, or a titanium and cobalt mixed metal. The head, liner and acetabular parts can be made of either metal, plastic or ceramic, or a combination of the above.
