Plain radiograph (a), photograph (b), surface contour map (c) and trace profile (d) of a retrieved MAGEC rod with a pin fracture. We suggest that ‘off-axis loading’ accounts for the initial spaced wear marks (circle) and the pin fracture (arrow) and the subsequent uncontrolled lengthening of the rod contributes to the longitudinal wear marks (box) and further massive material loss
