From: A biomechanics study on ligamentous injury in anterior-posterior compression type II pelvic injury

Variable Restricted group1 Restricted group2 T P value

Separation distance of anterior sacroiliac joint (mm) 11.4 ± 3.8 16.7 ± 4.2 2.880 0.028
  1. 1The separation distance when anterior sacroiliac ligament barely fails
  2. 2The separation distance when the anterior sacroiliac ligament, sacrotuberous ligament, and sacrospinous ligaments all fail
