type of joint between pelvic bones in the pelvic girdle

 In human anatomy, the pelvis (plural pelves or pelvises, sometimes also called pelvic region of the trunk) is the lower part of the trunk, between the abdomen and the lower limbs (legs).[1] The pelvis includes several structures:[1]

  • the bony pelvis, or pelvic skeleton, the part of the skeleton connecting the sacrum region of the spine to the femurs, subdivided into:
  • the pelvic cavity, typically defined as a small part of the space enclosed by the pelvic skeleton, delimited by the pelvic brim above and thepelvic floor below; alternatively, the pelvic cavity is sometimes also defined as the whole space enclosed by the pelvic skeleton, subdivided into:
  • the pelvic floor or pelvic diaphragm, below the pelvic cavity
  • the perineum, below the pelvic diaphragm

In the human, the pelvic skeleton is formed in the area of the back (posterior dorsal), by the sacrum and the coccyx (the caudal portion of the axial skeleton), and laterally and anteriorly (forward and to the side), by a pair of hip bones, the lower extremity, (parts of the appendicular skeleton). In an adult human being, the pelvic skeleton is thus composed of three large bones, and the coccyx  (3–5 bones); however, before puberty, each hip bone consists of three discrete (separate) bones — the iliumischiumpubis — that have yet to fuse at adulthood; thus, in puberty, the human pelvic skeleton can comprise more than 10 bones, depending upon the composition of the person’s coccyx.

There are four articulations within the pelvis: Sacroiliac joints (x2) ? between the ilium of the hip bones, and the sacrum. Sacrococcygeal symphysis ? between the sacrum and the coccyx. Pubic symphysis ? between the pubis bodies of the two hip bones.
