Living with Primary tethered cord syndrome

A neurological condition in which the spinal cord is held in place and can't move freely, causing leg weakness, back pain and bladder problems.

Understanding Primary tethered cord syndrome

Primary tethered cord syndrome is a rare neurological condition in which tissue attachments limit how freely the spinal cord can move in the spine.

Severity varies. It may involve foot and spine differences, leg weakness, loss of feeling in the legs, lower back pain, scoliosis and bladder control problems. Babies and children may have a tuft of hair, a dimple, skin color change or a fatty lump on the lower back. It can begin at birth or in infancy.

Signs & symptoms

Symptoms vary from person to person. GARD lists these:

  • Weakness in the legs
  • Loss of feeling in the lower limbs
  • Lower back pain
  • Scoliosis
  • Loss of bladder control
  • Hair tuft, dimple or fatty lump on the lower back

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include brain and nervous system specialists and genetic specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

    Bobby Jones Chiari & Syringomyelia Foundation and Spina Bifida Association may keep lists of experts for this condition.

Quick facts

Symptoms usually startNewborn and as an Infant

GARD says it occurs when tissue attachments limit the spinal cord's movement. It may result from improper growth of the neural tube before birth, which is closely linked to spina bifida. Other causes include spinal narrowing with age, spinal cord injury, tumors and infection.
