Pelvic Ligaments – Functional Anatomy

The major osseous structures of the pelvis are wrapped in a complex fascial structure that, like the osseous structures change and evolve as we age. In the first two decades, we have more boney pieces held together by cartilaginous plates that fuse as decades pass. Eventually, in our 4th or 5th decade, all of the joints, including the sacroiliac joint fused into one large structure. The ligaments atrophy as the bones fuse.

In this illustration, for clarity, they are shown as very separate structures. In reality, they appear more like thickened sections that are woven together into a larger whole.

Here is a section from Integrative Craniosacral – Transition to Integrative Bodywork on pelvic ligaments.


This site is undergoing changes. Starting in early 2020, we began changing the format of the posts to include more extensive self-care, illustrations, therapist notes, anatomy, and protocols. We’d love your feedback. We are adding posts and converting the old posts as quickly as time permits.

*This site is undergoing major changes. We are reformatting and expanding the posts to make it easier to read, more accessible, and
to include more patterns with better self-care. In the meanwhile, there will be inconsistency in formatting, content, and readability until we get the old posts updated. Please excuse our mess.
