Children hit developmental milestones as they grow, whether it’s learning to walk or potty training. These attachments cause an abnormal stretching of the spinal cord. Sometimes a small portion of the bony vertebrae (laminae) are removed to obtain better exposure or to decompress the spinal cord. Symptoms in infants and older children include: pain in the lower back. Releasing the tethering lesion; can be simple or highly complex requiring many hours or dissection under the microscope. to manifest problems with the bowel and bladder control. The dura is then opened, and the spinal cord and myelomeningocele are gently dissected away from the scarred attachments to the surrounding dura. Many children require only one untethering procedure. While spina bifida is one of the main causes of tethered spinal cord syndrome, in some instances, the condition could also be caused by: Spine trauma; Spine surgery; A spine tumor; Benign growths; Congenital deformities; A split spinal cord; Symptoms of Tethered Spinal Cord Syndrome. weakness or numbness in the legs or feet. Some researchers, noting that less severe spinal cord traction may remain asymptomatic in childhood, hypothesize that the age of symptom onset is related to the amount of cord stretch. At times we use a laser to sharply dissect tissue from the nerves. Director, Functional Neurosurgery Symptoms common to adult tethered cord syndrome include constant, often severe back and leg pain, which may extend to the rectum and genital area in some cases. Many children do not have symptoms at the time of diagnosis. Tethered cord syndrome refers to a group of neurological disorders that relate to malformations of the The course of the disorder is progressive. Tethered cord syndrome occurs when tissue attachments limit the movement of the spinal cord … Signs and symptoms of a tethered cord can include the following: A crooked toe. The pathophysiology is unclear and may be conceptually incongruent with current understanding of typical tethered cord syndrome. Tethered cord is one of the conditions treated by the specialists at the Weill Cornell Chiari CARE program. (Photo 5) All Rights Reserved, background-image - a woman looking at a screen, Neurosurgery Research & Education Foundation, Dermal sinus tract (a rare congenital deformity), Thickened/tight filum terminale (a delicate filament near the tailbone), Fatty tumor or deep dimple on the lower back, Back pain, worsened by activity and relieved with rest, Progressive or repeated muscle contractions. Children with a tethered cord who receive appropriate treatment can have a normal life expectancy. This can cause the spinal cord to stretch out as the spine grows, leading to possible nerve damage, pain and other symptoms. That’s why most of the symptoms are in the low back and legs (lower spinal cord and nerves). “Occult tethered cord” Symptoms consistent with tethered cord (as reviewed) and exclusion of other conditions and co-morbidities No imaging evidence of fatty or thickened filum and conus at “normal” position Essentially, a normal standard MRI Learn more about the NREF and make a donation today. Tethered Cord What is ‘tethered cord’?

Trouble with bowel or bladder control, such as difficulty in toilet training in a toddler, keeping a dry diaper with a baby, loosing control in a toilet trained child or no being able to hold urine until getting to the bathroom. Tethered cord syndrome, lipomeningomyelocele, or meningomyelocele, includes a group of congenital diseases,( which child is born with) may include swelling in the midline of the lower back of the spine, filled with CSF ( brain water and nerves), or this may be containing fat entangling the nerves meant to supply the lower limbs. Baltimore. The spinal cord therefore becomes stretched, and symptoms may begin during times of rapid growth, at around 2 years, 7-8 years, and with puberty. As a child continues to grow, the spinal cord can become stretched, causing damage and interfering with the blood supply to the spinal cord. A conservative … Tethered cord syndrome (TCS) after myelomeningocele (MMC) repair (or secondary TCS) is a challenging condition characterized by neurological, orthopedic, and urological symptoms, which are combined with a low-lying position of the conus medullaris and damage to the stretched spinal cord owing to metabolic and vascular derangements. This condition is called a tethered spinal cord. However, if left untreated, these symptoms may become quite severe. On rare occasions, years after the original surgery, a re-tether may develop for certain types of tethered cords causing radiating leg pain, persistent back pain or bladder problems. Typical symptoms are: Lower back pain; Leg pain; Muscle weakness, manifesting in toes and legs; Urinary incontinence or urinary retention; Fecal incontinence or chronic constipation; Foot, leg and spinal deformities; Symptoms usually exacerbate over time. problems standing or walking. In surgically treated patients, pain relief can often be achieved, and long-term neurological stabilization tends to persist more often than it does in conservatively treated patients. Omar Zalatimo, MD MPH MHA FAANS Clinically, tethered cord syndrome usually presents with slowly progressive lower extremity weakness, lower extremity or back pain, scoliosis, gait abnormalities, and/or changes in bowel/bladder function, reflexes, foot-shape, or leg length.

Background: Tethered cord syndrome is a well-defined condition, the management of which is fairly uniform. In contrast, occult tethered cord syndrome is a recently defined entity, where the management is still controversial. Infants and children with congenital tethered cord syndrome may also have tufts of hair, dimples, skin discoloration, or benign fatty tumors on the lower back. After some time, follow-up with the neurosurgeon may be on an as needed basis or if symptoms return. Tethered Cord Syndrome is a condition where the spinal cord is abnormally attached within the bony spine causing stretching and tugging that can be painful and lead to disability. However, another aspect of that diagram to the right is that some believe that a tethered cord can also pull on the brain and cause it to hang low in the skull base, intersecting with a disease called “Chiari Malformation”. Normally, the spinal cord moves freely through fluid within the spine from the base of the brain down to the lower back. Hairy patch on the lower back. Tethered cord syndrome may not result in any symptoms early in life, but may become problematic later due to age-related changes in the spine, resulting in: 1. Patients may present with any combination of the following 4: 1. (Photo 3), A crooked crease between the buttocks. Signs of a tethered cord include skin observations such as a hairy tuft, sacral dimple or a fatty mass on the back. These children will have symptoms related to the bottom of the spinal cord. The site navigation utilizes arrow, enter, escape, and space bar key commands. The child usually can resume normal activities within a few weeks. The symptoms listed below are some of the ways in which tethered spinal cord syndrome may be exhibited in children: Lesion on the lower back. The AANS does not endorse any treatments, procedures, products or physicians referenced in these patient fact sheets. A lesion, skin discoloration, or hairy patch on the lower back may be an indication that a problem may exist below the skin. Surgery in adult patients with a tethered cord syndrome should be reserved for those with symptoms. This situation may require additional surgery. It is estimated that 20-50% of children with spina bifida defects that are repaired shortly after birth will require surgery at some point to untether the spinal cord. Needles are inserted into the lower body to monitor nerve function even as the child is asleep. unusual anatomy of the anus. When the spinal cord becomes tethered, it’s attached to nearby tissues. 17 tethered cord syndrome patients report severe fatigue (32%) 23 tethered cord syndrome patients report moderate fatigue (43%) 10 tethered cord syndrome patients report mild fatigue (18%) 3 tethered cord syndrome patients report no fatigue (5%) There shall be difficulty in the bowel control. As the body grows, however, the spinal cord then becomes stretched and damaged by the abdominal attachment. You could see a weak foot or foot deformity, delayed walking, bowel issues or back pain in older kids. If they have surgery as soon as possible after tethered cord and bladder symptoms appear, they have a better chance of recovery and less of a … The spinal cord includes the bundle of nerves that controls leg movement and sensation as well as bladder function. Untethering is generally performed only if clinical signs or symptoms of deterioration are observed. The spinal cord typically divides into small nerve roots at the L2 vertebral body. When Tethering of Spinal Cord occurs in children it causes the spinal cord to stretch abnormally as the child grows, but in adults the spinal cord stretches with any activity the individual does which may be at work or at home. Factors in adult onset tethered cord syndrome include: transient stretching of the spine, mechanical constriction/narrowing of the spinal canal, and spinal trauma, all in the presence of an already tightly tethered c… The spinal cord is wrapped in a covering, or sheath, that allows bones and tissues to expand during childhood and adolescence. In people with spina bifida (myelomeningocele), the spinal cord fails to separate from the skin of the back during development, preventing the spinal cord from ascending normally; therefore, the spinal cord is low-lying, or tethered. During development of the spinal cord, tissue and fat, or other body elements that do not belong near the spinal cord can become attached to the spinal cord. In such cases, the strain on the spinal cord increases, leading to increasing sensory and motor problems, as well as loss of bladder and bowel control. The condition can be treated with surgery to prevent future nerve damage. (Photo 3) A crooked crease between the buttocks. Back pain, worsened by activity and relieved with rest. The entirety of symptoms that may be associated with that condition is referred to as tethered cord syndrome.

Although the skin is separated and closed at birth, the spinal cord stays in the same location after the closure. People with Tethered Cord (TC) can have sacral dimples, discoloration, and hairy patches on their lower back that can lead a doctor to investigate further, however, some have no external signs at all. Signs and symptoms of a tethered cord can include the following: The diagnosis of a tethered spinal cord is made by obtaining a Magnetic Resonance Imaging or MRI of the spine. Children may have several symptoms of tethered spinal cord, including: A tuft of hair at the base of the spine; A sacral dimple – a dimple or divot at the end of the spine. (Photo 1) A dimple above the gluteal crease (the crease in the buttocks) (Photo 2) Long hair (longer than 1 inch) growing on the back over the spine. In patients with a lipomyelomeningocele, the spinal cord will have fat at the lower tip, and this fat may connect to the fat that overlies the thecal sac (a fluid filled sac that the spinal cord “floats” within) that may also lead to thethering. If a tethered cord is suspected, one or more tests may be necessary to confirm the diagnosis. A child with tethered spinal cord syndrome will usually develop symptoms. Symptoms can worsen during periods of rapid growth, as the tethered cord becomes more stretched. A follow-up MRI is usually performed sometime after surgery. No menu assigned! When it is tethered, it pulls during activity, causing pain and other problems. Treatment of a tethered cord syndrome does require follow-up with the treating neurosurgeon and typically with physical therapy/ occupational therapy. Left and right arrows move across top level links and expand / close menus in sub levels. Complications include infection, bleeding, and damage to the spinal cord or myelomeningocele, which may result in decreased muscle strength or bladder or bowel function. In most cases, there are no problems at birth. TCS means your spinal cord is pulled down and tied (tethered) within your spinal column. Skin discoloration on the lower back. The lower tip of the spinal cord is normally located opposite the disc between the first and second lumbar vertebrae in the upper part of the lower back. (Photo 4). Tethered spinal cord syndrome is a neurologic disorder caused by tissue attachments that limit the movement of the spinal cord within the spinal column. A tethered spinal cord occurs when the spinal cord is attached to tissue around the spine, most commonly at the base of the spine. Children may have several symptoms of tethered spinal cord, including: Back pain or shooting pain in the legs Weakness, numbness or problems with muscle function in the legs Tab will move on to the next part of the site rather than go through menu items. Enter and space open menus and escape closes them as well. As a result, the spinal cord can’t move freely within the spinal canal.

Replacing and securing the bone (laminoplasty movie coming soon). This trend is due to improvement in neurological examinations and in the interpretation of imaging studies. … Some have kyphosis (rounded back) and scoliosis (curved spine). The surgery involves opening the scar from the prior closure down to the covering (dura) over the myelomeningocele. This information is provided as an educational service and is not intended to serve as medical advice. Bladder dysfunction, in particular, is common.

Tethered Spinal Cord is in almost all cases accompanied by a condition called as spina bifida. Surgery for a tethered spinal cord can prevent future irreversible nerve damage which can severely affect a child's bladder and leg function and quality of life. In addition to myelomeningocele and lipomyelomeningocele discussed above, the following are other causes of tethered cord that vary in severity of symptoms and treatment: The symptoms listed below are some of the ways in which tethered spinal cord syndrome may be exhibited in children: Although it is rare, a patient with tethered spinal cord can continue undiagnosed into adulthood. tethered cord symptoms. This syndrome is closely associated with spina bifida. A spinal ultrasound will often be ordered to help diagnose a tethered cord. Fatty tumor or deep dimple on the lower back.
