The ilium (/ ˈ ɪ l i ə m /) (pl.: ilia) is the uppermost and largest region of the coxal bone, and appears in most vertebrates including mammals and birds, but not bony fish.All reptiles have an ilium except snakes, although some snake species have a tiny bone which is considered to be an ilium.
The joint is strong, supporting the entire weight of the upper body. It is a synovial plane joint with irregular elevations and depressions that produce interlocking of the two bones. [1] The human body has two sacroiliac joints, one on the left and one on the right, that often match each other but are highly variable from person to person. [1]
Over-diagnosis and attention on herniated discs has led to the SI joint becoming an underappreciated pain generator in an estimated 15% to 25% of patients with axial low back pain. [1] [8] [3] [5] [6] [7] The ligaments in the sacroiliac are among the strongest in the body and are not suspected by many clinicians to be susceptible to spraining ...
The left lower quadrant (LLQ) of the human abdomen is the area left of the midline and below the umbilicus. The LLQ includes the left iliac fossa and half of the left flank region. The equivalent term for animals is left posterior quadrant. Important organs here are: the descending colon and sigmoid colon; the left ovary and fallopian tube; the ...
the dorsal region encompassing the upper back; the lumbar region encompassing the lower back. the sacral region occurring at the end of the spine, directly above the buttocks. The regions of the back of the arms, from superior to inferior, include the cervical region encompassing the neck, the acromial region encompassing the shoulder,
The severity of symptoms of damage to the iliohypogastric nerve can show whether damage occurred above or below the anterior superior iliac spine. [6] Bone may be harvested from the nearby iliac crest for use elsewhere in the body. [5] As the subcostal nerve lies close to the anterior superior iliac spine, this is put at risk of damage. [5]
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.
It is thinner at the center than at the extremities, and ends in the anterior and posterior superior iliac spines. The surface of the crest is broad, and divided into external and internal lips, and an intermediate line. About 5 cm behind the anterior superior iliac spine there is a prominent tubercle on the outer lip.
