The testing samples in the three groups are shown. (A) In the sacroiliac group, fixation was done by two standard sacroiliac screws in S1 and S2 and one intramedullary pubic ramus screw. (B) In the cemented group, the same configuration was used but with the addition of cement augmentation of the sacroiliac screws. (C) For the transsacral group, one single transsacral screw through S1 was combined with a pubic ramus screw.
