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. [2]
Lumbarization of sacral vertebra 1, seen as 6 vertebrae that do not connect to ribs. Lumbarization is an anomaly in the spine. It is defined by the nonfusion of the first and second segments of the sacrum. The lumbar spine subsequently appears to have six vertebrae or segments, not five.
Bertolotti's syndrome is characterized by sacralization of the lowest lumbar vertebral body and lumbarization of the uppermost sacral segment. It involves a total or partial unilateral or bilateral fusion of the transverse process of the lowest lumbar vertebra to the sacrum, leading to the formation of a transitional 5th lumbar vertebra.
SACRAL syndrome is a congenital condition characterized by spinal dysraphism, anogenital, cutaneous, renal and urologic anomalies, associated with an angioma of lumbosacral localization. [ 1 ] See also

Currarino syndrome is an inherited congenital disorder where either the sacrum (the fused vertebrae forming the back of the pelvis) is not formed properly, or there is a mass in the presacral space in front of the sacrum, and there are malformations of the anus or rectum. It occurs in approximately 1 in 100,000 people. [1]
SAO JOAO DO POLESINE, Brazil (Reuters) -Scientists in Brazil announced the discovery of one of the world's oldest fossils believed to belong to an ancient reptile dating back some 237 million ...
The spinal cord and its nerve roots are put back inside the spine and covered with meninges. In addition, a shunt may be surgically installed to provide a continuous drain for the excess cerebrospinal fluid produced in the brain, as happens with hydrocephalus. Shunts most commonly drain into the abdomen or chest wall. [citation needed]
