A and B showed that the rotation angle and displacement of SIJ in the states of intact ASL and ASL resection, respectively. R_int and T_int represented the rotation angle and displacement in the state of intact ASL. R_sec and T_sec represented the rotation angle and displacement in the state of ASL resection. The symbol “*” indicated that there was a statistical difference between the two states, that was, p < 0.05. SIJ: Sacroiliac joint. ASL: Anterior sacroiliac ligament
