A tethered cord is when part of the spinal cord is attached inside the spinal canal, and the spinal cord cannot move freely.</p> <h3>More to Know</h3> <p>The spinal cord is a bundle of nerves that sends signals between the <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/brain-nervous-system.html/">brain</a> and other parts of the body. It runs down the center of the backbone (spine) through a fluid-filled channel called the spinal canal.</p> <p>The spinal cord carries messages back and forth between the brain and body. A tethered spinal cord can cause problems with getting these messages through.</p> <p>Kids with tethered cords don't always have symptoms. But as a child grows, the nerves in the spinal cord can become stretched. When this happens, signals may not travel as easily back and forth between the brain and certain parts of the body. A child may have back pain; leg pain; numbness or tingling in the legs; leg weakness; trouble walking; a frequent or sudden need to pee; <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/constipation.html/">constipation</a>; difficulty peeing, or pee or poop accidents. Some kids have a birthmark, dimple, patch of hair, or bump on their lower back.</p> <p>A child may be <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/birth-defects.html/">born</a> with a tethered cord, or it may develop after an injury or surgery.</p> <h3>Keep in Mind</h3> <p>Surgery to release the spinal cord is the main treatment for a tethered cord. The doctor will make a&nbsp;small opening near the backbone, remove any connections, and then close the opening with medical glue or stitches. These will dissolve on their own and do not need to be removed.</p> <p><em>All A to Z dictionary entries are regularly reviewed by KidsHealth medical experts.</em></p>
A to Z: Spinal StenosisSpinal stenosis is a narrowing of the spaces in the spine, or backbone, where the spinal cord is located. Pressure placed on the spinal cord causes pain and disruption to some body functions.https://kidshealth.org/ws/RadyChildrens/en/parents/az-spinal-stenosis.html/adbe7f3e-67c9-4d4f-aa56-fea2dff4da17

Brain and Nervous SystemIf the brain is a central computer that controls all the functions of the body, then the nervous system is like a network that relays messages back and forth to different parts of the body.

Magnetic Resonance Imaging (MRI): Cervical SpineA cervical spine MRI can help evaluate various symptoms and also help diagnose tumors, bleeding, swelling, infections, or inflammatory conditions in the vertebrae or surrounding tissues.https://kidshealth.org/ws/RadyChildrens/en/parents/test-mri-spine.html/6eeef9ef-2b05-499c-a47a-599e302e13ae
Magnetic Resonance Imaging (MRI): Lumbar SpineA lumbar spine MRI is a painless test that uses a magnetic field and radio waves to produce detailed pictures of the bones, disks, and other structures in the lower back.https://kidshealth.org/ws/RadyChildrens/en/parents/mri-lumbar.html/9590ba4f-a832-441e-a171-dd45bb9e042c
Spina BifidaSpina bifida is a birth defect that involves the incomplete development of the spinal cord or its coverings. It's usually detected before a baby is born and treated right away.https://kidshealth.org/ws/RadyChildrens/en/parents/spina-bifida.html/a13499de-e5ce-40a1-a8bd-12bd447f75cf
X-Ray Exam: Cervical SpineThis X-ray can, among other things, help find the cause of neck, shoulder, upper back, or arm pain. It's commonly done after someone has been in an automobile or other accident.https://kidshealth.org/ws/RadyChildrens/en/parents/xray-c-spine.html/2e5c4519-896e-49e0-8100-3dc777f7488f
