| SPINA
BIFIDA CAUSED BY MEDICAL MALPRACTICE
Tragically,
each year 200 to 400 babies, or approximately 2 to 4 babies each
day, are born with spina bifida in Canada. This is approximately 1
in every 400 life births.
What Is
Spina Bifida?
Spina
bifida occurs when the tiny ribbon of tissue that by the 28th day
of pregnancy normally folds inward to form a tube connecting the
brain and spinal cord in a developing infant fails to close
completely. When this happens, the baby's backbone, spine, and
brain can be affected.
There are
three forms of spina bifida:
• Occulta
In this form of spina bifida which is usually symptomless,
there is a small defect or gap in one or more of the vertebrae
of the spine. The spinal cord and nerves are usually normal, and
most affected children have no disabilities.
• Meningocele
This is the rarest form of spina bifida, consisting of a
cyst or lump of membranes surrounding the spinal cord pokes
through the open part of the spine. The cyst, which can vary in
size, can generally be removed by surgery, allowing for normal
development of the child.
• Myelomeningocele
This is the most severe form of spina bifida, can result
when the cyst holds the membranes surrounding the spinal canal,
nerve roots of the spinal cord, and, often, even the cord
itself. Sometimes, however, there is no cyst, and instead there
is only a fully exposed section of the spinal cord and nerves.
Spinal fluid may leak out in such cases. Babies affected by this
form of spina bifida are at high risk of infection until the
back is closed surgically. Antibiotic treatment may offer
temporary protection. Even with surgery, however, there is often
some leg paralysis, as well as bladder and bowel control
problems. Many children also have hydrocephalus (the excessive
accumulation of cerebrospinal fluid in the brain).
Can
Spina Bifida Be Prevented?
Up to 60
percent of all cases of spina bifida could be prevented if the
mother had sufficient amounts of folic acid everyday before and
during early pregnancy, before the neural structures close in the
developing baby. In particular, women who already have had a baby
with spina bifida or another neural tube disorder (NTD), as well
as women who have spina bifida, diabetes or seizure disorders,
should consult their health care providers before another
pregnancy about the amount of folic acid to take.
Can
Spina Bifida Be Detected Prenatally?
Spina
bifida often can be detected before birth using two or more tests.
First, most health care providers now routinely offer pregnant
women a blood test called the maternal serum alpha-fetoprotein
(MSAFP) screening test (part of the "triple screen").
This test detects pregnancies at higher-than-average risk of spina
bifida and other NTDs, as well as some other birth defects, such
as Down syndrome. If a woman has a high MSAFP test result (not
caused by factors such as a miscalculation of fetal age), her
health care provider probably should also recommend two additional
tests that are accurate in detecting severe spina bifida. These
are a detailed ultrasound examination of the fetal spine, and
amniocentesis to measure levels of alpha fetoprotein (AFP) in
amniotic fluid. When spina bifida is diagnosed before birth,
health care professionals can provide parents with information and
support. They can plan for delivery in a medical center that is
properly equipped so that the baby can have any necessary surgery
or treatment soon after birth. They can discuss with parents the
potential benefits of a cesarean delivery prior to the onset of
labor so as to reduce the likely severity of paralysis in the
babies. They can discuss with parents the possibility of prenatal
surgery to try to repair severe spina bifida before birth. Such
surgery may help prevent future paralysis and may reduce the need
for shunts to drain fluids from the brain. Lastly, they can
provide the parents with the option of an abortion in cases of
severe spina bifida.
How Can
Spina Bifida Be Treated?
Treatment,
if any is required, is determined by the type and severity of the
spina bifida. Babies with meningocele, which does not involve the
spinal cord, will generally undergo surgery, usually with no
paralysis. Most children with meningocele are able to develop
normally. However, affected children should be evaluated for
hydrocephalus and for bladder problems so they can be treated
promptly if these problems exist.
Babies with
myelomeningocele, the most severe form of spina bifida, usually
require surgery within 24 to 48 hours after birth. Physicians
surgically reposition exposed nerves and spinal cord back inside
the spinal canal and cover them with muscle and skin. Prompt
surgery helps prevent additional nerve damage from infection or
trauma. Unfortunately, any nerve damage that has already occurred
prior to the surgery cannot be reversed and limb paralysis, as
well as bladder and bowel problems usually remain.
As soon as
possible following the surgery, a physical therapist begins
working with the parents to teach them how to exercise their
baby's legs and feet to prepare the baby for walking with leg
braces and crutches. Approximately 70 percent of affected children
will be able to walk, although some will require these devices.
Yet, approximately, 30 percent of children will require the use of
a wheelchair.
About 90
percent of those children affected with the most severe form of
spina bifida develop hydrocephalus, or fluid on the brain. Without
immediate treatment, mental retardation and other neurologic
damage may result. If this condition does develop, fluid can be
drained from the brain through the surgical implantation of a
special tube called a shunt, that runs under the skin into the
chest or abdomen, and allows the fluid passes harmlessly into the
child's body.
Most
children with severe spina bifida will also have a tethered spinal
cord, a condition in which the spinal cord does not slide up and
down with movement as it should, because it is held in place by
surrounding tissue. While most children have no symptoms from
this, some suffer from the progressive loss of function in their
legs, and a few will develop scoliosis (curvature of the spine).
If the spinal cord is surgically untethered shortly after these
symptoms begin, the child may be able to return to his or her
usual level of functioning.
Other
chronic complications associated with severe spina bifida include
obesity, gut and urinary tract disorders, psychological and sexual
issues, and learning disabilities.
What Can
We Do If Our Child Was Born With Spina Bifida?
If your
child was born with a severe form of spina bifida and the mother
was not screened appropriately during the pregnancy, or the
parents were not advised of treatment options, or of the
possibility of an abortion, you should immediately contact a
competent lawyer. The lawyer will be able to work with you to
determine what options you may have regarding your health care
provider's negligence, so as to protect your child's future. |
