Why do some people have complications?
The term 'spina bifida occulta' is, in fact, not one but two separate conditions which have completely different consequences. This leads to confusion when such a diagnosis is used without qualification.
For the majority of people with spina bifida occulta it is a minor fault involving one vertebra in the lower back. The unfortunate use of this term for such a minor fault can lead to distress for the person concerned. However, it should be considered as insignificant, both for that person and his or her children.
For a small number of people with spina bifida occulta the fault is more extensive. Either the split in the spine is bigger, or may involve two or more vertebrae. There may be visible signs on the skin such as a mole or naevus (birthmark), a dimple or sinus (hole), or a patch of hair. This type of spina bifida occulta is significant.
There may be associated difficulties which may include the following: foot deformity, weakness and reduced sensation of the legs, change in hand function, bladder infections and incontinence and bowel problems.
These problems arise because the spinal cord becomes tethered to the backbone. Often a child who is previously symptomless may experience difficulties during the rapid growth of adolescence. This is because the nerves of the spinal cord are stretched and the symptoms may become progressively worse.
It is important to consult a GP, who, if appropriate, can refer to a neurosurgeon. Specialist scanning procedures such as MRI (magnetic resonance imaging) give a clear picture of the nerves and spinal column and the neurologist will be able to advise on the most appropriate treatment.
People with spina bifida occulta and progressive (worsening) symptoms of a stretched or tethered spinal cord need to have an operation on their lower spine to release the tension in the spinal cord. This is often a fairly simple and effective procedure, but occasionally the operation is very complicated and involves a (2% - 5%) risk of failure. It is often possible to improve symptoms in the legs with this operation, but it is rare for bladder function to return to normal. The main purpose of a "detethering operation" is to stop any further deterioration in leg or bladder function and it is important that a neurosurgical assessment is made as early as possible after the onset of symptoms. The operation is probably best done by those neurosurgeons who have a special interest in the condition.
