Hemivertebra is a failure of vertebral formation carrying a risk of causing progressive scoliosis if it is fully segmented. When two hemivertebrae are present on the opposite sides of the spine and are separated by at least one normal vertebra, this condition then exemplifies a hemimetameric shift. The hemimetameric shift is often benign for progression, but it may also be problematic depending on the separation and the nature of the two hemivertebrae involved. If the two opposing hemivertebrae are close merely separated by one or two normal vertebrae, they tend to cause two small kinks in the spine and minimal cosmetic deformity. However, if the two hemivertebrae are in different regions of the spine, separate curves are then produced and the spine may become unbalanced, causing spinal decompensation and significant cosmetic deformity. In this article, we report one case for whom a hemimetameric shift was managed via a one-stage posterior hemivertebral resection.展开更多
