Articulations of pelvis. Anterior view. Articulations of pelvis. Posterior view. Sacroiliac joints are paired C-shaped or L-shaped joints capable of a small amount of movement [2] (2–18 degrees, which is debatable at this time) that are formed between the auricular surfaces of the sacrum and the ilium bones.
Posterior view of human female and male to show the comparison of their buttocks Some female clothing, such as the bikini or panties , show part of the female buttocks ( woman on left ). Thongs , in particular, leave almost all of the buttocks exposed ( woman on right ).
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 same human pelvis, front imaged by X-ray (top), magnetic resonance imaging (middle), and 3-dimensional computed tomography (bottom). The pelvis (pl.: pelves or pelvises) is the lower part of an anatomical trunk, [1] between the abdomen and the thighs (sometimes also called pelvic region), together with its embedded skeleton [2] (sometimes also called bony pelvis or pelvic skeleton).
The lesser pelvis (or "true pelvis") is the space enclosed by the pelvic girdle and below the pelvic brim: between the pelvic inlet and the pelvic floor. This cavity is a short, curved canal, deeper on its posterior than on its anterior wall. [1] Some sources consider this region to be the entirety of the pelvic cavity.
The posterior portion, known as the iliac tuberosity, is elevated and rough, for the attachment of the posterior sacroiliac ligaments and for the origins of the sacrospinalis and multifidus. Below and in front of the auricular surface is the preauricular sulcus, more commonly present and better marked in the female than in the male; to it is ...

The internal surface of the body is part of the wall of the lesser pelvis and gives origin to some fibers of the obturator internus. The wing (Latin: ala) is the large expanded portion which bounds the greater pelvis laterally. It has an external and an internal surface, a crest, and two borders—an anterior and a posterior.
