Are congenital vertebral anomalies and spina bifida cystica aetiologically related?

Abstract
Radiological records of 104 patients with multiple vertebral anomalies without apparent spina bifida and 112 infants with spina bifida cystica were surveyed and the incidences of hemivertebrae and of rib, vertebral body and vertebral arch fusions were recorded. The distributions of these 4 anomalies along the vertebral axis were not statistically different between the 2 age groups. Multiple vertebral anomalies and anencephaly-spina bifida cystica may be etiologically related.
