Spina Bifida – Spina Bifida Occulta, Meningocele, Myelomeningocele

Spina bifida is a birth defect in which the spine and the membranes surrounding the spinal cord do not develop or close properly. This can result in damage to the spinal cord and nerves, leading to a range of physical and neurological impairments.

Symptoms

There is currently no cure for spina bifida; however, the condition occurs in three main forms, each with varying degrees of severity.

• Spina Bifida Occulta
  This is the mildest form of spina bifida. A small gap is present in the spine, but there is no opening on the back. Most people with spina bifida occulta experience few or no symptoms and do not develop significant impairments.
• Meningocele
  In this form of the condition, a fluid-filled sac protrudes through an opening in the baby’s back. Because the spinal cord is not contained within the sac, nerve damage is usually minimal or absent. Children with meningocele may experience minor impairments.
• Myelomeningocele
  This is the most severe form of spina bifida. Part of the spinal cord and surrounding nerves protrude through an opening in the baby’s back. The resulting impairments can range from mild to severe and may include loss of sensation in the feet and legs, reduced mobility, and problems with bladder and bowel control.

Diagnosis and Treatment Options

Spina bifida is often detected during pregnancy through prenatal screening tests, including blood tests, ultrasound examinations, and amniocentesis. In some cases, the condition is not diagnosed until after birth.

Doctors may suspect spina bifida based on an unusual marking or opening on a baby’s back. Imaging studies such as X-rays, computed tomography (CT) scans, or magnetic resonance imaging (MRI) scans may be used to examine the spine and confirm the diagnosis.

Babies born with myelomeningocele or meningocele generally require more extensive treatment than those with spina bifida occulta. Treatment often involves surgery before birth (foetal surgery) or shortly after delivery. Early surgical intervention can reduce the risk of further spinal cord damage caused by infection, trauma, or swelling.

In some cases, nerve damage associated with the condition may result in paralysis of the legs, learning difficulties, bladder and bowel dysfunction, or a build-up of fluid within the brain (hydrocephalus).

Although there is no cure for spina bifida, a range of treatments can help manage symptoms and improve quality of life. Your doctor will discuss the available treatment options, potential benefits, and associated risks to help you make informed decisions about your child’s care.

Foetal surgery, when appropriate, may reduce the need for future procedures to treat hydrocephalus and may improve the likelihood of independent mobility and better long-term outcomes.

Recovery

Recovery and ongoing care will vary depending on the type and severity of spina bifida. Follow-up care may include:

• Rehabilitation, as required
• Follow-up MRI scans
• Possible additional surgery, if required
• Physiotherapy
• Occupational therapy
• Psychological support, as needed
• Pain medication, as required
• Urology assessment and ongoing monitoring of bladder and kidney function
• Participation in support groups and educational programs for children and families
