Inflammation of the arachnoid membrane in the spinal canal, it can be caused by trauma, spinal surgery, hemorrhage or infection. It can result in severe pain. For more information see:


Basilar Invagination

A condition in which a portion of the C2 vertebra (called the odontoid) compresses the brain stem. For more information see:


Ehlers-Danlos Syndrome

A group of inherited disorders marked by extremely loose joints, hyperelastic skin that bruises easily, and easily damaged blood vessels. For more information see:



A buildup of fluid in the ventricles of the brain. This condition is usually treated by placing a ventricle-peritoneal shunt to drain the fluid. For more information see:


ICP (Intracranial Hypertension, Pseudotumor Cerebri)

Increased intracranial pressure can be due to a rise in cerebrospinal fluid pressure. It can also be due to increased pressure within the brain matter caused by a mass (such as a tumor), bleeding into the brain or fluid around the brain, or swelling within the brain matter itself.

An increase in intracranial pressure is a serious medical problem. The pressure itself can damage the brain or spinal cord by pressing on important brain structures and by restricting blood flow into the brain.

Many conditions can increase intracranial pressure. For more information see:


There are many types and causes of scoliosis, including:

  • Congenital scoliosis. Caused by a bone abnormality present at birth.
  • Neuromuscular scoliosis. A result of abnormal muscles or nerves. Frequently seen in people with spina bifida or cerebral palsy or in those with various conditions that are accompanied by, or result in, paralysis.
  • Degenerative scoliosis. This may result from traumatic (from an injury or illness) bone collapse, previous major back surgery, or osteoporosis (thinning of the bones).
  • Idiopathic scoliosis. The most common type of scoliosis, idiopathic scoliosis, has no specific identifiable cause. There are many theories, but none have been found to be conclusive. There is, however, strong evidence that idiopathic scoliosis is inherited.


Tethered Cord

A condition where scar tissue forms and tethers, or holds, the spinal cord to the dura, the soft tissue membrane that surrounds it. This scar tissue prevents the normal flow of spinal fluid around the spinal cord and impedes the normal motion of the spinal cord within the membrane.
