Condition Description. Spina bifida occurs in the first month of fetal life as the result of a failure of part of the spine to fully form due to an unknown cause. Maternal nutritional state, exposure to radiation, drugs and chemicals as well as a genetic predisposition may act together to cause neural tube defects.he embryonic cells that form the neural tube and eventually form the spine do not fully develop. The spinal cord therefore lacks a bony covering due to defects in the vertebra bone formation. The nervous system tissue of the spinal cord can also be affected.
