Inferior to the anterior superior iliac spine is a rounded protuberance called the anterior inferior iliac spine. Both of these iliac spines serve as attachment points for muscles of the thigh. Posteriorly, the iliac crest curves downward to terminate as the posterior superior iliac spine.

What are the landmarks of the pelvic brim?

Its size is defined by its edge, the pelvic brim. The borders of the pelvic inlet: Posterior – sacral promontory (the superior portion of the sacrum) and sacral wings (ala). Lateral – arcuate line on the inner surface of the ilium, and the pectineal line on the superior pubic ramus.

What attach to PSIS?

As the most posterior projection of the iliac crest, it serves for the attachment of the long posterior sacroiliac ligament, which blends with the sacrotuberous ligament, as well as the multifidus and gluteus maximus muscles. Figure 1 depicts the muscular and ligamentous attachments to the PSIS.

Are hip and pelvis the same?

What is pubic rami fracture?

Pubic rami fractures are classified as fractures of the anterior pelvic ring and from a biomechanical point of view they are considered stable fractures that allow full weight bearing. As a consequence conservative treatment consisting of analgesia and mobilisation with weight bearing as tolerated is generally applied.

How serious is a fractured pelvis?

Pelvic rings often break in more than one place. A mild fracture (such as may happen from the impact of jogging) may heal in several weeks without surgery. However, a serious pelvic fracture can be life-threatening and may involve damage to the organs the pelvis protects.
