Congenital Hemivertebra #spine #bones #anatomy #radiology

A dorsal hemivertebra is a congenital spinal deformity that occurs during fetal development. It affects one of the vertebrae of the spine, causing an abnormal, wedge-shaped formation of the vertebral body.
Dorsal hemivertebrae are congenital, meaning they are present at birth. They result from abnormal development of the affected vertebra during embryonic growth. This abnormality occurs due to a failure in the normal segmentation and formation of the vertebra, leading to an asymmetrical shape.
A dorsal hemivertebra can disrupt the normal alignment of the spine. When multiple dorsal hemivertebrae are present in close proximity, they can lead to spinal curvature disorders such as scoliosis or kyphosis. The severity of these spinal deformities depends on the number, location, and size of the affected hemivertebrae.
