Congenital vertebral anomalies are a collection of malformations of the spine. Most, around 85%, are not clinically significant, but they can cause compression of the spinal cord by deforming the vertebral canal or causing instability. This condition occurs in the womb. Congenital vertebral anomalies include alterations of the shape and number ...
Pathophysiology. [] The sacroiliac joint is a true diarthrodial joint that joins the sacrum to the pelvis. [ 1 ][ 8 ][ 16 ][ 17 ] The sacrum connects on the right and left sides to the ilia (pelvic bones) to form the sacroiliac joints. The pelvic girdle is made up of two innominate bones (the iliac bones) and the sacrum.
In human anatomy, the sacral plexus is a nerve plexus which provides motor and sensory nerves for the posterior thigh, most of the lower leg and foot, and part of the pelvis. It is part of the lumbosacral plexus and emerges from the lumbar vertebrae and sacral vertebrae (L4-S4). [1] A sacral plexopathy is a disorder affecting the nerves of the ...
Anatomical terms of bone. [ edit on Wikidata] The sacrum (pl.: sacra or sacrums[ 1 ]), in human anatomy, is a large, triangular bone at the base of the spine that forms by the fusing of the sacral vertebrae (S1–S5) between ages 18 and 30. [ 2 ] The sacrum situates at the upper, back part of the pelvic cavity, between the two wings of the pelvis.
The sacroiliac joint is a paired joint in the pelvis that lies between the sacrum and an ilium. Due to its location in the lower back, a dysfunctional sacroiliac joint may cause lower back and/or leg pain. The resulting leg pain can be severe, resembling sciatica or a slipped disc. While nonsurgical treatments are effective for some, others ...
Sacrovertebral angle. Lumbar vertebrae are yellow, and sacrum is green. Anatomical terminology. [ edit on Wikidata] The sacrum is curved upon itself and placed very obliquely, its base projecting forward and forming the prominent sacrovertebral angle when articulated with the last lumbar vertebra . It is also known as the "lumbosacral angle".
Caudal regression syndrome. Caudal regression syndrome, or sacral agenesis (or hypoplasia of the sacrum), is a rare birth defect. It is a congenital disorder in which the fetal development of the lower spine —the caudal partition of the spine—is abnormal. [1] It occurs at a rate of approximately one per 60,000 live births.
