Spinal muscular atrophy is inherited in an autosomal recessive pattern, which means that the defective gene is located on an autosome. Two copies of the defective gene – one from each parent – are required to inherit the disorder: the parents may be carriers and not personally affected.
Spina bifida (SB; /ˌspaɪnə ˈbɪfɪdə/, [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]
Brown-Séquard syndrome occurs when the spinal cord is injured on one side much more than the other. [30] It is rare for the spinal cord to be truly hemisected (severed on one side), but partial lesions due to penetrating wounds (such as gunshot or knife wounds) or fractured vertebrae or tumors are common. [31]
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 ...
NTDs are one of the most common birth defects, affecting over 300,000 births each year worldwide. [2] For example, spina bifida affects approximately 1,500 births annually in the United States, or about 3.5 in every 10,000 (0.035% of US births), [ 1 ] [ 3 ] which has decreased from around 5 per 10,000 (0.05% of US births) since folate ...
Short ribs at the first lumbar vertebra, which is thus a transitional vertebra, since lumbar vertebrae normally do not have ribs attached to them. Transitional vertebrae have the characteristics of two types of vertebra. The condition usually involves the vertebral arch or transverse processes. It occurs at the cervicothoracic, thoracolumbar ...
Identify the level of the spinal cord where myelopathy is located. This is especially useful in cases where more than two lesions may be responsible for the clinical symptoms and signs, such as in patients with two or more cervical disc hernias [11] Follow-up the progression of myelopathy in time, for example before and after cervical spine surgery
Once the spinal injury has occurred, one of two things may happen. Firstly, hemorrhaging within the spinal cord may cause compression, which damages the spinal cord even further. Another consequence of myelomalacia is improper circulation of blood to the area damaged, resulting in further damage to the spinal cord. [citation needed]
