The posterior border of the ala of sacrum, shorter than the anterior, also presents two projections separated by a notch, the posterior superior iliac spine and the posterior inferior iliac spine. The posterior superior iliac spine serves for the attachment of the oblique portion of the posterior sacroiliac ligaments and the multifidus.
The ilium is a bone of the pelvic girdle with four bony projections, each serving as attachment points for muscles and ligaments: Anterior superior iliac spine; Anterior inferior iliac spine; Posterior superior iliac spine; Posterior inferior iliac spine
The sacrotuberous ligament is attached by its broad base to the posterior superior iliac spine, the posterior sacroiliac ligaments (with which it is partly blended), to the lower transverse sacral tubercles and the lateral margins of the lower sacrum and upper coccyx.
The posterior border of the ala, shorter than the anterior, also presents two projections separated by a notch, the posterior superior iliac spine and the posterior inferior iliac spine. The former serves for the attachment of the oblique portion of the posterior sacroiliac ligaments and the multifidus; the latter corresponds with the posterior ...
The pain is often a mild to moderate ache around the dimple or posterior superior iliac spine region. [12] The pain may become worse and sharp while doing activities such as standing up from a seated position or lifting the knee towards the chest during stair climbing.
Below, it has the following attachments: posteriorly, to the whole length of the iliac crest, between the attachments of the transverse abdominal and Iliacus; between the anterior superior iliac spine and the femoral vessels it is connected to the posterior margin of the inguinal ligament, and is there continuous with the iliac fascia. [2]
Laterally, the ligament attaches onto the posterior part of the inner lip of the iliac crest. [1] More precisely, its lateral attachment is by two main bands: [2] the superior band (which is one of the attachments of the quadratus lumborum muscle) attaches onto the iliac crest anterior to the sacroiliac joint.
The posterior sacroiliac ligament is situated in a deep depression between the sacrum and ilium behind; it is strong and forms the chief bond of union between the bones. It consists of numerous fasciculi , which pass between the bones in various directions.
