Spina Bifida: An Overview for Families

What is this condition?

Spina bifida is a group of neural-tube conditions in which the spine and tissues around the spinal cord do not form normally early in pregnancy. The spectrum includes spina bifida occulta, closed spinal dysraphism, meningocele and open myelomeningocele. Severity varies widely; the label alone cannot predict walking, bladder, learning or long-term independence.

What symptoms can it cause?

• An open sac or skin-covered swelling on the back
• A dimple, hairy patch, fatty lump, birthmark or abnormal cleft in closed forms
• Leg weakness, foot deformity or altered sensation
• Bladder/bowel dysfunction, hydrocephalus or Chiari-related symptoms may coexist

How is it assessed and diagnosed?

Prenatal ultrasound may identify open defects; fetal MRI is selected in some centres. After birth, examination determines whether the lesion is open, skin-covered or associated with neurological deficits. MRI of brain and spine, renal/bladder studies and orthopaedic assessment are planned according to type. Not every simple shallow dimple requires imaging.

Treatment without surgery

Care is multidisciplinary: paediatrics, neurosurgery, urology, orthopaedics, rehabilitation, nursing and social/educational support. Bladder protection, bowel routine, skin care, nutrition, mobility aids and treatment of hydrocephalus may be as important as closure of the back. Folic acid before conception and in early pregnancy reduces risk but does not eliminate every case.

When is surgery or a procedure considered?

Open myelomeningocele usually requires early closure to protect exposed tissue and reduce infection, although closure cannot restore nerves already malformed. Closed lesions are operated when tethering, compression, drainage or progressive neurological/urological harm is likely. Hydrocephalus may need shunt or selected endoscopic treatment.

Treatment and procedure options

• Postnatal closure of open myelomeningocele
• Prenatal repair in highly selected programmes where available
• Tethered-cord release for progressive symptomatic tethering
• Shunt or endoscopic treatment of hydrocephalus
• Lifelong urological, orthopaedic and rehabilitation care

Risks from the disease and from treatment

Risks from disease include meningitis, hydrocephalus, kidney damage, pressure sores, deformity and functional loss. Surgery can cause infection, CSF leak, wound breakdown, neurological change and retethering. Long-term outcomes improve when bladder and skin problems are identified early. No procedure is risk-free. General risks include anaesthetic problems, bleeding, infection, blood clots and delayed healing. Neurological risks depend strongly on the exact structure being treated and may include new weakness, numbness, speech or vision change, seizure, cerebrospinal-fluid leakage, need for another procedure or failure to obtain the hoped-for relief. The surgeon should discuss the risks that apply to the individual case.

Recovery and follow-up

Follow-up continues through growth and adulthood. Walking ability may change as the child grows. Kidney ultrasound/urodynamic plans, bowel programme, shunt awareness, school inclusion and transition to adult services should be organised rather than waiting for a crisis. Recovery is not judged only by the first few days. Pain control, wound care, nutrition, safe mobilisation, physiotherapy and planned follow-up all matter. Some symptoms improve quickly after pressure is relieved; others recover gradually over weeks or months, and permanent nerve injury may not fully reverse.

Preparing for your consultation

Bring the original MRI/CT images or digital files, written reports, previous prescriptions, a current medicine list, and any operative or pathology records. For sudden warning symptoms, use the nearest emergency department rather than waiting for a routine appointment.
