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 ventrogluteal site is located in a triangle formed by the anterior superior iliac spine and the iliac crest, and may be located using a hand as a guide. [15] The ventrogluteal site is less painful for injection than other sites such as the deltoid site. [17]
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 ...

The most common site of insertion is the antero-medial aspect of the upper, proximal tibia as this site lies just under the skin and is easily located. Other insertion sites include the anterior aspect of the femur, the superior iliac crest, proximal humerus, proximal tibia, distal tibia and the sternum (manubrium). [1]
There is a 0.09-3.2% risk of hematomas at the injection site and a 0.18% risk of local anaesthetic intoxication. [2] There are also case reports of pneumoretroperitoneum using continuous infusion, [7] bladder puncture with a modified block under very special conditions [8] and postoperative neuropathy. [9]
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.
