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. This sixth lumbar vertebra is known as a transitional ...
The conus medullaris (or lower termination of the spinal cord) normally terminates at or above the L1-2 disk space (where L1 is the first, or topmost lumbar vertebra). After about 3 months of age, a conus below the L1-2 disk space may indicate a tethered cord and termination below L3-4 is unmistakably tethered.
In neurology, a lipomyelomeningocele is a type of closed neural tube defect that affects around 3 to 6 babies out of 100,000 births. [1] [2] It is an example of a spinal lipoma, which is a collection of adipose tissue, or fat, that is located at or around the spinal cord.
Spinal muscular atrophy (SMA) is a rare neuromuscular disorder that results in the loss of motor neurons and progressive muscle wasting. [3] [4] [5] It is usually diagnosed in infancy or early childhood and if left untreated it is the most common genetic cause of infant death. [6]
Diastematomyelia is a "dysraphic state" of unknown embryonic origin, but is probably initiated by an accessory neurenteric canal (an additional embryonic spinal canal.).) This condition may be an isolated phenomenon or may be associated with other segmental anomalies of the vertebral bodies such as spina bifida, kyphoscoliosis, butterfly vertebra, hemivertebra and block vertebrae which are ...
The weakness is indicated as hypotonia, or lack of muscle tone, which can make an infant seem unstable. [1] [5] Eventually, most patients develop joint contractures or fixed joint deformities. [6] Children may be slow with their motor skills; such as rolling over, sitting up or walking, or may not even reach these milestones of life. Some of ...
Nearly 1,200 Americans shared with BI their financial regrets. Many of the baby boomer respondents said they had regrets about preparing for retirement.
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]
