Introduction to Spina Bifida
Spina bifida is a defined as any abnormal development of the bones of the spine that display a typical pattern, with or without the involvement of the brain, nerves or covering of the nerves (meninges). It is the most common congenital spine abnormality. The term spina bifida covers a range of malformations that always include deformities of certain parts of the vertebrae, the spinous process and vertebral arch. Some have described this process as a failure of these bones to fuse during early fetal development. Classification Spina bifida is broken down into two categories: spina bifida occulta and open spina bifida. These subtypes are distinguished by the absence or presence of nerves, fluid that surrounds the nerves (CSF), and the meninges that are included within the deformity. See Table 1. Table 1.

Diagnosis Since there is no opening to the skin, spina bifida occulta can only be seen on x-ray or MRI. Certain clinical findings such as dimpling of the skin or a hairy patch at the base of the spine may trigger further investigation by a physician. Underlying spinal nerve abnormalities can be seen in these situations. There is inconclusive evidence that this type of deformity is related to back pain, scoliosis, or nighttime bed-wetting. A large study showed that in patients not complaining of back pain, almost 20% had uncomplicated spina bifida occulta. If you have an abnormality on an x-ray, it does not always mean that this is causing your pain. The diagnosis of open spina bifida is usually made at birth or during prenatal ultrasound screening. It accounts for about 10% of all patients with spina bifida. There can be a mass outside the body at the base of the spine containing nerves (myelomeningocele) or the nerves may be absent in the mass (meningocele). Usually the deformity is covered with a thin membrane (spina bifida cystica), or it can be open to the environment (spina bifida aperta) and drainage of spinal fluid is seen. Treatment There is no specific treatment for occult spina bifida if the abnormality is limited to the bone. Usually these deformities are found at the last lumbar vertebrae (L5) or at the first sacral vertebrae (S1). However, deformities of the spine can lead to degenerative changes later in life that may require intervention. Open spina bifida and underlying spinal abnormalities associated with occult spina bifida are treated by a neurosurgeon. The goal of surgery is to preserve the nerves, restore the normal anatomy, and close the defect. This delicate surgery is carefully performed under magnification while using special monitors to help identify the nerves. Surgery will help to reduce the risk of infection (meningitis) and reduce the progression of long-term disability. Considerations for patients and their families The diagnosis of spina bifida may be devastating for the parents of these children. The neurosurgeon’s role not only includes operative management but also education. Children born with a myelomeningocele (Figure 2) have a 90% chance of survival. Furthermore, they have an 80% chance of normal intelligence and around an 85% chance of walking with or without assistance. Long-term problems include: short stature, lack of leg development, scoliosis, and bowel and bladder difficulties. There are many other conditions closely associated with open spina bifida. Approximately 80 to 90% of patients will develop hydrocephalus (increase in the size of the fluid filled spaces in the brain). This can be treated effectively, using a shunt (plastic tube under the skin from the brain to the abdomen) in the early stages of development. Children may have many other abnormalities, throughout their body, which must be recognized. Several medical and surgical specialties will contribute to the overall care of these children during their entire lives. It is essential to maintain a support network, not only for the patient, but also the family, in order to provide optimal outcomes for all patients with spina bifida.
