What is Spina Bifida?

By: Jo Johnson - Updated: 3 Sep 2013 | comments*Discuss
 
Spina Bifida; Occulta; Myelomeningocele;

Spina Bifida is the most common of birth defects caused by the incomplete closure of the neural tube (the beginnings of the central nervous system) during the first stages of foetal development.

The vertebrae do not form properly, or can be missing altogether and nerves and tissues can be left unprotected or their growth can encroach on other structures; this can result in mobility, sensation or neurological problems. It is normally seen at the lumbar and sacral regions of the spine.

Symptoms of Spina Bifida

There are different types of spina bifida, each with different symptoms and severity.Spina bifida occulta is very common and signs can include a ‘dimple’ on the skin, sometimes with unusual hair growth or a small birthmark may be present. It is a very mild form and is not usually problematic.

Spina bifida myelomeningocele is a serious form of the condition and occurs when the normal membranes that cover the spinal cord do not form properly and can create a sac-like structure that contains cerebrospinal fluid and nerves, some of which may stem from the spinal cord. It is clearly visible at birth and treatment planning should begin as early as possible to prevent further deterioration of the spinal cord and central nervous system.

Symptoms can be loss of sensation below the affected area, occasional paralysis, neurological problems such as bowel or bladder incontinence.

It is very common for sufferers of this form of spina bifida to have an accompanying condition called hydrocephalus. This happens when fluid collects around the brain, surgery is often necessary to insert a shunt to help drain the fluid.

The last type of spina bifida is called meningocele and is not particularly common. As in spina bifida cystica, a sac forms from the membranes of the spinal cord, but damage to nerves is minimal or none and functions are not normally affected, therefore treatment is unusual.

Treatment of Spina Bifida

There is no cure for spina bifida but there are treatments available to prevent affected functions from deteriorating.Surgery is normally performed soon after diagnosis, and the opening in the vertebrae is closed and nerves are placed into their proper position. The damage to the nerves cannot be reversed.

Many sufferers will need to be educated on the correct selection and usage of appropriate continence aids and sometimes help with mobility will need to be explored. Physiotherapy may be useful to those with minor mobility problems.Counselling and therapy should be made available if required regarding social and sexual issues, and children should be included in the decision making process as a way of helping them understand the condition.

Foetal surgery is being researched and developed all the time and doctors are exploring ways of treating spina bifida in the uterus before birth.

Preventative Measures

It is commonly thought that spina bifida is related to a lack of folic acid in the mothers’ diet prior to conception and during the first three months of conception.

Folic acid supplements are strongly recommended as to consume the required recommended amounts through normal diet is extremely difficult.

There is thought to be a genetic link to this condition also.

Spina bifida is a very common defect amongst newborns. There is no cure but treatment may help reduce the condition deteriorating. There are different types of spina bifida, all of which vary in severity.

I am an adult with spina bifida occulta found in my 20's as a result of chronic utis waiting 5 hrs in emergency depts for medication.Not only was there a neurogenic bladder but double ureters & a host of other conditions made worse as a result .So take thyroxine . Fortunately seeing a Prof with a strong microscope & ability to customise antibiotics who has kept my kidneys clear but when he doesn't see me 3 weekly the complications set in which is near paralysis of lower back & excrutiating pain resolved by upping the antibiotic medication .The time before last pyuria was 80 & urgent care not testing. Can't Sepsisbe fatal? Seven years ago a haematuria was found not properly investigated so lead to cardiac arrest [ dying 3x at time ]. When I go on the forums in UK & USA I notice there are many people at wits end with back pain or chronic utis . Could they be among 10% where nothing is wrong? Who is perpetuasting this myth / They have a lot to answer for . How many people with SB die of a heart attack ? Was it caused by chronic utis?

I was born with Spinal Bifida and had surgery at three months old.I have a significant amount of scar tissue and a significant scar on my lower back. I have been told that surgery would not be an option due to the scar area..I I have a history of: Spina Bifida, Bilateral Radiculopathy mild facet arthropathy in all disk L 4-5mild opposing endplate fatty marrow diskogenic changes are present. more pronounced posteriorly. central disk protrusion with inferior extrusion is slightly asymmetric towards the right.the disk herniation indents the ventral aspect of the thecal sac L5-S1 broad based disk bulge encroaches into the neural foramina there is moderate bilateral, foraminal stenosis. AT L4-5 there is annular spondylitic disk bulge with super imposed central/ right paracentral disk protrusion closely approaching the descendingL5 right nerve root. mild right lateral recess and right foraminal narrowing is present.
