Abstract:

BACKGROUND: Complete structure of the sacroiliac complex, the sacrotuberous ligament and the sacrospinous ligament in the back of the pelvis is important to the stability of the pelvis.
OBJECTIVE: To observe the structure of the sacroiliac joint ligaments and study the functions of the ligaments on the stability of the sacroiliac joint.
METHODS: The sacrospinous ligament, sacrotuberous ligament, and pubic symphysis and the ligaments of the sacroiliac joint from 20 embalmed pelvis specimens were observed via the anterioposterior approach to study their anatomical structure.
RESULTS AND CONCLUSION: The sacroiliac joint ligaments can be divided into three groups: the anterior sacroiliac ligaments, the interosseous sacroiliac ligaments and the posterior sacroiliac ligaments; the symphysis pubis ligaments; the sacrospinous and sacrotuberous ligaments. These ligaments have two main functions. They can connect the vertebral column with the pelvic, and maintain the stability of the pelvic ring.
