Spina bifida (SB; / ˈ s p aɪ n ə ˈ b ɪ f ɪ d ə /; [9] Latin for 'split spine') [10] is a birth defect in which there is incomplete closing of the spine and the membranes around the spinal cord during early development in pregnancy. [1] There are three main types: spina bifida occulta, meningocele and myelomeningocele. [1]
Patients with spina bifida have a neural tube that has failed to completely form. This is most commonly in the lower back area in the region of the conus medullaris or cauda equina. Therefore, spina bifida affects the bowel similarly to a lower motor neuron spinal cord injury, resulting in a flaccid, unreactive rectal wall.
The MOMS Trial was a clinical trial that studied treatment of a birth defect called myelomeningocele, which is the most severe form of spina bifida. The study looked at prenatal (before birth) and postnatal (after birth) surgery to repair this defect. The first major phase concluded that prenatal surgery had strong, long-term benefits and some ...
Spina bifida is a birth defect that affects the lowest part of the spine and occurs when a fetus's neural tube does not fully close, causing the backbone that protects the spinal cord not to form ...
Spina bifida occulta means hidden split spine. [20] In this type of neural tube defect, the meninges do not herniate through the opening in the spinal canal. [19] The most frequently seen form of spina bifida occulta is when parts of the bones of the spine, called the spinous process, and the neural arch appear abnormal on a radiogram, without ...
Tethering of the spinal cord tends to occur in the cases of Spina bifida with mylomeningocele. In most people the spine grows faster than the spinal cord during development which causes the end of the spinal cord to appear to rise relative to the bony spine next to it. By the time of birth the spinal cord is located between L1 and L2. In a baby ...
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 ...
Other secondary causes include space-occupying lesions, ankylosing spondylitis, rheumatoid arthritis, and Paget's disease. Less commonly, the cause of spinal stenosis may be present at birth as seen in achondroplasia, spina bifida, and certain mucopolysaccharidoses. [15]
