Spinal Dysraphism (Spina bifada occulta – myelomeningocele)
Group of congenital malformations due to a failure of the two halves of some spinous vertebrae to fuse, leading to a defect in the vertebral column protrusion and dysplasia of spinal cord. Affects about 2 in 1000 live births. Severity varies from an asymptomatic spina bifada occulta to myelomeningocele. Defects can be open or closed and generally need surgical repair of the lesion.
Present in most cases. Loss of protective sensation and proprioception pressure lesions post-surgical correction of deformity.
