Spina Bifida

Spina bifida is a congenital defect of the spine where the spinal cord and its meninges are exposed due to a gap in the backbone. It occurs when the neural tube, which forms the brain and spinal cord during fetal development, fails to close completely.

Types of Spina Bifida

• Spina Bifida Occulta: This is the mildest form of spina bifida, where there is a small gap in the spine but no opening or sac on the back. It often goes undiagnosed as it may not cause any symptoms.
• Meningocele: In this type, a sac containing the meninges (the protective membranes covering the spinal cord) protrudes through an opening in the spine.
• Myelomeningocele: This is the most severe form of spina bifida, where both the meninges and the spinal cord protrude through an opening in the spine. It can cause significant nerve damage and disability.

Symptoms of Spina Bifida

The symptoms of spina bifida vary depending on the type and severity of the condition. Common symptoms include:

• Weakness or paralysis of the legs
• Lack of bladder and bowel control
• Hydrocephalus (fluid accumulation in the brain)
• Orthopedic problems, such as clubfoot or scoliosis
• Skin problems, such as pressure sores or wounds
• Bowel and bladder infections
• Latex allergy
• Obesity and related health issues
• Depression and anxiety

Treatments for Spina Bifida

Treatment for spina bifida depends on the type and severity of the condition. The goals of treatment are to prevent infection, promote healing, and manage symptoms.

• Surgery: Surgical closure of the opening in the spine is usually performed within 48 hours of birth to prevent infection and further damage to the spinal cord.
• Shunting: A shunt may be inserted to drain excess fluid from the brain and relieve hydrocephalus.
• Physical Therapy: Physical therapy can help improve mobility, strength, and flexibility in children with spina bifida.
• Occupational Therapy: Occupational therapy can help individuals with spina bifida develop skills for daily living and independence.
• Bracing and Orthotics: Braces and orthotics can help manage orthopedic problems, such as scoliosis or clubfoot.
• Bowel and Bladder Management: Individuals with spina bifida may require catheterization or bowel management programs to maintain bladder and bowel function.
• Pain Management: Pain management strategies, such as medication or alternative therapies, can help alleviate chronic pain associated with spina bifida.
• Psychological Support: Psychological support and counseling can help individuals with spina bifida cope with the emotional and social challenges of living with a disability.

Complications of Spina Bifida

Individuals with spina bifida are at risk for various complications, including:

• Infection (meningitis or sepsis)
• Hydrocephalus
• Chiari II malformation (a condition where the brain tissue extends into the spinal canal)
• Syringomyelia (a condition where a fluid-filled cavity forms within the spinal cord)
• Tethered cord syndrome (a condition where the spinal cord becomes attached to the spine)

Prevention of Spina Bifida

While spina bifida cannot be completely prevented, the risk can be reduced by:

• Folic acid supplementation during pregnancy (400-800 mcg per day)
• Avoiding certain medications and substances during pregnancy
• Maintaining a healthy weight and diet during pregnancy
• Getting regular prenatal care
