Hemivertebrae are wedge-shaped vertebrae and therefore can cause an angle in the spine (such as kyphosis, scoliosis, and lordosis). Among the congenital vertebral anomalies, hemivertebrae are the most likely to cause neurologic problems. [5] The most common location is the midthoracic vertebrae, especially the eighth (T8). [6]
Butterfly vertebra (also known as sagittal cleft vertebra) is a rare congenital spinal anomaly characterized by the presence of a sagittal cleft within a vertebral body, giving it a butterfly-like appearance on imaging. This condition arises due to incomplete fusion of the lateral halves of a vertebra during embryonic development.
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] Some babies are born with very small differences compared to typical development, and others have significant changes.
Although Hippocratic doctors were aware of developmental abnormalities involving the lower spine, the first person to describe a spinal spina bifida was a Persian physician Al-Razi (Rhazes, 865–925 AD). [87] [88] [89] He gave the earliest accurate account of the morbid anatomy associated with spina bifida. [90]
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 ...
Generally, diseases outlined within the ICD-10 codes Q65-Q79 within Chapter XVII: Congenital malformations, deformations and chromosomal abnormalities should be included in this category. Wikimedia Commons has media related to Congenital diseases and disorders of musculoskeletal system .
KFS is associated with many other abnormalities of the body, hence thorough evaluation of all patients with fused cervical vertebrae at birth is required. Furthermore, it is unclear whether KFS is a unique disease, or if it is one part of a spectrum of congenital spinal deformities. [citation needed] KFS is usually diagnosed after birth.
