Pubic symphysis

  • The pubic symphysis (or symphysis pubis; latin: symphysis pubis, symphysis pubica) is a transitional joint or hemiarthrosis of the pelvis located between the two pubic bones.

    The pubic symphysis joins the left and right pubic bones at the symphyseal surface. The pubic symphysis is covered by fibrous cartilage called the interpubic disc. The pubic symphysis is strengthened by two strong ligaments - the superior pubic ligament and the inferior pubic ligament.

    The superior pubic ligament runs from the left to the right pubic crest.

    The inferior pubic ligament extends from the left to the right inferior pubic ramus.

    The pubic symphysis allows very little movement, usually a shift to two millimeters and a one degree rotation.
