Bearing-Foreign Material Deposition on Retrieved Co-Cr Femoral Heads: Composition and Morphology

Figure 1

Diffused-light macroscopic images of the five femoral heads showing extensive bearing-foreign material deposits. The circles in the middle of images of heads A, B, C, and E delimit the reflection of the camera lens, which was eliminated by digital combination of photographs. The cross-mark (+) in each image identifies a corresponding site of SEM-based morphologic characterization in Figure 4, and the asterisks () designate the sites of EDS evaluation in Figure 5.
