# Spinal dysraphism

Spinal dysraphism

This is a group of  disorders arising from abnormal embryo- logical formation of  tissues; all are associated with a progressive neurological deficit as the result of  spinal cord tethering and traction or cord compression. There is a strong association with spina bifida. In diastematomyelia, there is an abnormal bony or cartilag inous spur projecting across the middle of  the vertebral canal, dividing the dural tube and spinal cord in two. Between 50% and 70% of  patients are seen to have a skin naevus, dimple or hairy patch when the spine is examined. Surgical r elease of  the tethering has variable results. Spinal dysraphism
