prothesis metal poisoning

INTRODUCTION: Metallosis is produced by friction between prothesis pieces, release of metal particles that can enter systemic circulation provoking cobalt or chromium poisoning. No studies have been found in which the mobilization of metal particles causes haemodynamic instability. CASE PRESENTATION: We present the case of an 85 years old male with metallosis, programmed for washing and prothesis extraction (Girldlestone procedure). During pseudotumor drainage and washing, patient presented sudden desaturation and hypotension refractory to volume and phenylephrine administration...

We report on our morphological and spectrometric findings with complete acetabuloplastics. The histomorphological investigation revealed the formation of a narrow cicatricial coat round the prothesis. The collagenous tissue borders on a zone of granulation tissue of varying width. Granular foreign matter can be found in cicatrical tissue especially in the extracellular space and in granulation tissue in macrophages. Only a few partigles turned out to be iron in the Prussian blue reaction. Spectral analysis proved the hip and thigh-bones to contain more than 0...
