Fracturing of Revision of a Cobalt-chrome Femoral Head after Fracturing of a Ceramic Femoral Head, with Diffuse Metallosis. Case Report

Abstract

We presente a case of a fracture of a cobalt-chrome femoral head after revision of a hip total prosthesis with ceramic femoral head fracture. During surgery we found the cobalt- chrome femoral head fracture, wear of the polyethylene and massive metallosis in muscular and cartilaginous tissue. Both femoral stem and acetabular cup were stable and without apparent wearing. After surgical debridement, we promoted the substitution of the femoral head and the acetabular polyethylene by similar ones. After 12 months of follow- up, the patient has no pain complaints, function limit or systemic signs associated with malign metallosis.

Haemodynamic instability during hip prothesis removal due to metallosis: An acute chrome/cobalt intoxication? A case report

“…Metallosis treatment is based on the prothesis removal, profuse washing and new arthroplasty [3] , [4] . Metal intoxication needs fluid replacement therapy, chelators such as dimercaptopropanesulfonate and N -acetylcisteine, and adjuvants including ascorbic acid [2] , [5] .…”

Metalose: Causa Rara de Anemia Hemolítica Autoimune

“…Uma das complicações raras da artroplastia da anca é a metalose, que está geralmente associada a próteses metal-metal e tende a ocorrer esporadicamente com articulações cerâmica-cerâmica, sobretudo quando há fractura do insert cerâmico. [10][11][12][13] É muitas vezes mascarada por um suposto processo infeccioso.…”
