Figure 4

Particles observed in periprosthetic tissues. (A–C) CoCrMo metal particles of sub-micron size group in leukocyte infiltrated areas (A); they show a high contrast in back-scattered electron image due to their high density (B); the EDS spectrum shows peaks of Co, Cr, and Mo (C). (D–F) chromium phosphate particles, tens to hundreds of microns in size usually surrounded by a collagenous capsule (D), showing low density in back scattered electron image (E), and peaks in Cr, O, and P in EDS spectrum (F).
