Male pelvis.

Female pelvis.

The pelvic cavity is a body cavity that is bounded by the bones of the pelvis. Its oblique roof is the pelvic inlet (the superior opening of the pelvis). Its lower boundary is the pelvic floor.

The pelvic cavity primarily contains reproductive organs, the urinary bladder, the pelvic colon, and the rectum. The rectum is placed at the back of the pelvis, in the curve of the sacrum and coccyx; the bladder is in front, behind the pubic symphysis. In the female, the uterus and vagina occupy the interval between these viscera. The pelvic cavity also contains major arteries, veins, muscles, and nerves. These structures coexist in a crowded space, and disorders of one pelvic component may impact upon another; for example, constipation may overload the rectum and compress the urinary bladder, or childbirth might damage the pudendal nerves and later lead to anal weakness.

Structure

Pelvis

The pelvis has an anteroinferior, a posterior, and two lateral pelvic walls; and an inferior pelvic wall, also called the pelvic floor. The parietal peritoneum is attached here and to the abdominal wall.

Lesser pelvis

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. Some consider this region to be the entirety of the pelvic cavity. Others define the pelvic cavity as the larger space including the greater pelvis, just above the pelvic inlet.

The lesser pelvis is bounded in front and below by the pubic symphysis and the superior rami of the pubes; above and behind, by the sacrum and coccyx; and laterally, by a broad, smooth, quadrangular area of bone, corresponding to the inner surfaces of the body and superior ramus of the ischium, and the part of the ilium below the arcuate line.

roof: pelvic brim
posterior: sacrum, coccyx	lateral: obturator internus	anterior: pubic symphysis
floor: pelvic floor

The lesser pelvis contains the pelvic colon, rectum, bladder, and some of the sex organs. The rectum is at the back, in the curve of the sacrum and coccyx; the bladder is in front, behind the pubic symphysis. In the female, the uterus and vagina occupy the interval between these viscera.

The pelvic splanchnic nerves arising at S2-S4 are in the lesser pelvis.

Greater pelvis

The greater pelvis (or "false pelvis") is the space enclosed by the pelvic girdle above and in front of the pelvic brim. It is bounded on either side by the ilium; in front it is incomplete, presenting a wide interval between the anterior borders of the ilia, which is filled by the muscles and fascia of the anterior abdominal wall; behind is a deep notch on either side between the ilium and the base of the sacrum that is filled by the thoracolumbar fascia and associated muscles.

It is generally considered part of the abdominal cavity (this is why it is sometimes called the false pelvis). Some consider this region part of the pelvic cavity, while others reframe the classification question by calling the combination the abdominopelvic cavity.

The greater pelvis supports the intestines (specifically, the ileum and sigmoid colon), and transmits part of their weight to the anterior wall of the abdomen.

The femoral nerve from L2-L4 is in the greater pelvis, but not in the lesser pelvis.

Ligaments

Ligament	From	To
broad ligament of the uterus	uterus	side of pelvis
* mesovarium	ovary
* mesosalpinx	Fallopian tube	broad ligament of the uterus
* mesometrium
cardinal ligament	cervix & vagina	pelvic wall
ovarian ligament	ovary	uterus
round ligament of the uterus	ovary	travels through inguinal canal, ends at mons pubis
suspensory ligament of the ovary	ovary	pelvic wall

Arteries

• internal iliac artery
• median sacral artery
• ovarian artery

Nerves

• sacral plexus
• splanchnic nerves
• femoral nerve (greater pelvis)

Measurements

The pelvis can be classified into four main types by measuring the pelvic diameters and conjugates at the pelvic inlet and outlet and as oblique diameters.

Female pelvic cavity

Pelvic measurements

Measurement	From	To	Length
Transverse diameter (of inlet)	Between extreme lateral points of pelvic inlet		13.5–14 cm
Oblique diameter I	Right sacroiliac joint	Left iliopubic eminence	12-12.5 cm
Oblique diameter II	Left sacroiliac joint	Right iliopubic eminence	11.5–12 cm
Anatomical conjugate (true conjugate)	Pubic symphysis	Promontory	~12 cm
Obstetric conjugate	Retropubic eminence (posterior surface of symphysis)	Promontory	>10 cm
Diagonal conjugate*	Inferior pubic ligament	Promontory	11.5–12 cm
Straight conjugate	Lower border of symphysis	Tip of coccyx	9.5–10 cm
Median conjugate	Lower border of symphysis	Lower border of sacrum	11.5 cm
Transverse diameter (of outlet)	Between ischial tuberosities		10–11 cm
Interspinous distance	Between anterior superior iliac spines		26 cm (female)
Intercristal distance	Between furthest lateral points of iliac crest		29 cm (female)
External conjugate	Spinous process of fifth lumbar vertebra	Upper edge of symphysis	~20 cm
Intertrochanteric distance	Between femurs		31 cm
*Because the true conjugate can not be measured directly it is derived from the diagonal conjugate which is measured through the vagina.
