Metallosis, psoas abscess and infected hip prosthesis in a patient with bilateral metal on metal total hip replacement
نویسندگان
چکیده
Metal on metal hip (MoM) resurfacing / replacement has recently been one of the most discussed topics in orthopaedics. Significant revision rates and complications are associated with MoM. We report a patient presenting with infection of a total hip prosthesis in conjunction with a psoas abscess in which the presentation is complicated by radiological evidence of suspected metallic debris in the lower limb tissues and elevated chromium and cobalt levels, suggestive of metallosis secondary to MoM.

Adverse reaction to metal debris: metallosis of the resurfaced hip
The greatest concern after metal-on-metal hip resurfacing may be the development of metallosis. Metallosis is an adverse tissue reaction to the metal debris generated by the prosthesis and can be seen with implants and joint prostheses. The reasons patients develop metallosis are multifactorial, involving patient, surgical, and implant factors. Contributing factors may include component malposi...
متن کاملMetallosis of the Resurfaced Hip
Metallosis of the hip is usually defined as aseptic fibrosis, local necrosis, or loosening of the prosthesis secondary to metallic corrosion and release of wear debris.8 It has also been defined as gray discoloration of the tissues of the joint, pain, an effusion, and elevated serum metal levels. Metallosis has been found with stainless steel, titanium, and cobalt chromium alloy femoral prosthe...
متن کاملApparent Skin Discoloration about the Knee Joint: A Rare Sequela of Metallosis after Total Knee Replacement
Introduction. Metallosis is a phenomenon most commonly associated with hip replacement. However it can occur in any metallic implant subject to wear. Wear creates metal debris, which is deposited in the surrounding soft tissue. This leads to many local adverse reactions including, but not limited to, implant loosening/osteolysis, pain, and effusion. In the deeper joints, for example, the hip, m...
متن کاملAggressive granulomatosis after cementless total hip arthroplasty as a result of inflammatory reaction to metal debris: case report.
Massive osteolysis and granulomatous pseudotumor tissue reactions are long-term complications of total hip replacement. It is a condition of localized bone resorption in contact with prosthetic material. It is speculated to be a consequence of metal hypersensitivity or inflammatory reaction to excessive wear. Ten years after total cementless hip replacement (metal on polyethylene surface), a 70...
متن کاملMetallosis: A diagnosis not only in patients with metal-on-metal prostheses
Although the real actual incidence of metallosis is unknown, it is described as a rare diagnosis with a 5% estimated incidence in the hip prosthetic replacements. The adoption of non-metallic articular prosthetic devices, made of polyethylene and ceramic, is the main reason to the diminishing number of reported cases. We present a case of metallosis with a clinical systemic presentation in a pa...
