a) Graph showing relative movement in µm at the augment/acetabular component interface under different loads and fixations. Screw fixation alone resulted in significantly more relative movement under 100% load. b) Graph showing relative movement in µm at the bone/augment interface under different loads and fixations. Under full load, screw fixation alone resulted in significantly more relative movement. c) Graph showing relative movement in µm at the bone/component interface under different loads and fixations.
