What is PSIS pain?
Abstract. Objective: Pain at or around the posterior superior iliac spine (PSIS) is characteristic of sacroiliac joint (SIJ) -related pain. This pain can be treated by either a peri- or intra-articular injection into the joint, with the former being much easier to perform.
What bone is the PSIS on?
ASIS: known as the “hip bones.” These are the bones that stick out in the front of our pelvis and where we often rest our hands. PSIS: Look for the “dimples” or indentations in the lower back and then push deep into that area to palpate the PSISs.
What muscles attach at 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.
Where is the PSIS located?
The posterior superior iliac spine (PSIS) is located on the back, just above the buttock. It can usually be seen and felt under the indents just above the buttock.
What causes sacroiliac joints to get stuck?
When a patient has a slipped SI joint due to too much movement, it can cause normal wear and tear to occur quicker than it would otherwise. This can lead to the joint eventually locking up, resulting in hypomobility.

What muscles attach ASIS?
Structure. The anterior superior iliac spine refers to the anterior extremity of the iliac crest of the pelvis. This is a key surface landmark, and easily palpated. It provides attachment for the inguinal ligament, the sartorius muscle, and the tensor fasciae latae muscle.
What originates from PSIS?
Results: The gluteus maximus originates on the gluteal surface of the ilium, lumbar fascia, sacrum, sacrotuberous ligament, and laterally along the sacral margin….Results.
