Pelvis contains several joints, including the lumbosacral and sacroiliac joints, pubic and sacrococcygeal symphysis.

All joints are strengthened by various ligaments. Few of them are present throughout the spine extending into the pelvic girdle, but mostly they are ligaments only found in the pelvic part of the human body.

Ligaments of the pelvis include the following:

• Inguinal ligament
• Vertebro-pelvic ligaments:
  • Sacrospinous ligament
  • Sacrotuberous ligament
  • Iliolumbar ligament
• Long ligaments of the vertebral column:
  • Anterior longitudinal ligament
  • Supraspinous ligament
• Sacroiliac joint ligaments:
  • Anterior sacroiliac ligament
  • Posterior sacroiliac ligament:
    • Short posterior sacroiliac ligament
    • Long posterior sacroiliac ligament
• Ligaments of the pubic symphysis:
  • Superior pubic ligament
  • Inferior pubic ligament
• Ligaments of the sacrococcygeal symphysis:
  • Anterior sacrococcygeal ligament
  • Lateral sacrococcygeal ligament
  • Posterior sacrococcygeal ligament:
    • Deep posterior sacrococcygeal ligament
    • Superficial posterior sacrococcygeal ligament
