Sacroiliac Joint Ligaments: Importance of Stability

In a previous blog, the sacroiliac joint has been discussed as a source of lower back, buttock and posterior leg pain.

The importance of stability has been discussed in Ortho 2.0.  There are 4 central components:  Stability, Articulation (joint), Neuromuscular, and Symmetry (SANS).

Treatment options of sacroiliac joint dysfunction at the Centeno-Schultz Clinic include prolotherapy, PRP, IMS and autologous stem cell therapy.

The stability of the SI joint is dependent upon the integrity of the supporting ligaments.

These ligament include:

Dorsal  sacroiliac ligament:  joins the sacrum and the ilium and is composed of the long and short posterior SI ligaments.

iliolumbar ligament:    stretches from the transverse process of  L5 to iliac crest.

sacrospinous ligament:   triangular in shape attached by its apex to the ischial spine and medially, by its broad base, to the lateral margins of the  sacrum and coccyx.

sacrococcygeal ligaments:  stretches from the sacrum to the coccyx and thus dorsally across the sacrococcygeal symphysis.

Sacrotuberous ligament:  stretches from sacrum to the tuberosity of the ischium.
