3. Fig. 2
Graph of the mean differences in fractal dimension for vertical trabecular structures between baseline and exit macroradiograph. The values for the CI lines that do not cross the abscissa correspond to statistically significant changes in the fractal dimension for those sizes of trabeculae.

4. Fig. 3
Graph of the mean differences in fractal dimension for horizontal trabecular structures between baseline and exit radiograph. There were no statistically significant changes in the fractal dimension of horizontal trabeculae during the study period.

5. Fig. 4
Part of a macroradiograph of the centre of the femoral head showing the cancellous changes in the ROI used in quantifying alterations in bone structure. (A) Baseline radiograph (B) 18 months later showing thickened coarse vertical trabeculae and an overall reduction in trabecular number. The oblique line crossing the image is a scanning artefact. Original magnification ×3.4, reproduced at ×5.8.
