Figures & data
Figure 1. Anteroposterior radiograph taken 25 months after revision because of ceramic liner fracture, demonstrating metallosis around the stem neck. Note the loss of the superior part of the cobalt-chromium head.
Figure 2. The removed cobalt-chromium head showing loss of the superior part of the head because of severe wear.
Figure 3. Scanning electron micrograph of the retrieved polyethylene liner showing a sharp-edged alumina particle (asterisk) and irregular-shaped metal particle (arrow) embedded in the polyethylene. The elements contained in the material were identified using energy-dispersive radiographic analysis.
