What Is Tethered Spinal Cord Disease? Causes, Symptoms

Tethered spinal cord disease occurs when the spinal cord is abnormally attached to surrounding tissues, limiting its movement within the spinal canal. This condition can develop when the spinal cord doesn't grow at the same rate as the rest of the body during fetal development, leading to the spinal cord becoming stretched and fixed in place. Other causes of a tethered spinal cord can include spinal cord injuries, spinal infections, or spinal tumors. The tethering of the spinal cord can put pressure on the nerves and affect their function. Understanding the causes of tethered spinal cord disease is crucial for proper management and treatment.

What Are the Symptoms of Tethered Spinal Cord Disease

Tethered spinal cord disease can present with various symptoms, such as back pain, leg weakness, numbness, or tingling, changes in bowel or bladder function, and in severe cases, difficulty walking or standing. Children may exhibit symptoms like scoliosis, foot deformities, or delays in walking. As the spinal cord becomes stretched or compressed, these symptoms can worsen over time. It is essential to seek medical attention if experiencing any of these signs to prevent complications and ensure timely management of the condition.

Progressive weakness in the legs, leading to difficulty walking or standing for extended periods.
Numbness or tingling in the lower body, often affecting the legs, feet, or pelvic region.
Bladder or bowel dysfunction, such as urinary incontinence or constipation, due to nerve compression.
Back pain that worsens with activity and may also radiate down the legs, known as sciatica.
Muscle stiffness or tightness in the legs, causing discomfort and limited range of motion in the lower body.

Causes of Tethered Spinal Cord Disease

This condition can result from congenital factors such as spina bifida, where the spinal cord does not properly develop, leading to tethering. Additionally, acquired causes like spinal cord injuries or surgeries may also trigger tethering. In some cases, tumors or scar tissue formation in the spinal cord region can result in tethering as well. These various factors contribute to the tethering of the spinal cord, potentially causing symptoms and complications for affected individuals.

Congenital abnormalities during fetal development can lead to a tethered spinal cord.
Trauma or injury to the spinal cord can cause tethering, restricting its normal movement.
Tumors or abnormal growths in the spinal cord region may result in tethered spinal cord disease.
Inflammatory conditions like meningitis can lead to scarring and tethering of the spinal cord.
Surgical procedures in the spinal area can sometimes cause tethering, leading to the development of the disease.

Types Of Tethered Spinal Cord Disease

Tethered spinal cord disease encompasses various types, including primary spinal cord tethering and secondary spinal cord tethering. Primary spinal cord tethering is congenital, often resulting from abnormalities present at birth that cause the spinal cord to become stretched or fixed in place. Secondary spinal cord tethering can develop later in life due to conditions like spinal cord trauma, scarring from previous surgeries, or spinal cord tumors. Both types of tethered spinal cord disease can lead to symptoms such as back pain, leg weakness, and bladder dysfunction, requiring medical evaluation and potential surgical intervention.

Tethered spinal cord syndrome is a condition where the spinal cord is abnormally attached to surrounding tissues.
Primary tethered cord syndrome is congenital, often due to improper spinal cord development in utero.
Secondary tethered cord syndrome can result from spinal cord trauma, infection, or tumors.
Acquired tethered cord syndrome may develop later in life due to scarring or adhesions.
Symptoms of tethered spinal cord disease can include back pain, leg weakness, and bladder dysfunction.
Treatment for tethered spinal cord syndrome may involve surgical release to relieve tension on the spinal cord.

Risk Factors

Tethered spinal cord disease is associated with certain risk factors that may predispose individuals to this condition. Factors such as congenital anomalies, history of spinal surgery, spinal cord tumors, spinal infections, or previous spinal trauma can increase the likelihood of developing a tethered spinal cord. Additionally, conditions like spina bifida or other neural tube defects are known to contribute to the risk of this disorder. Understanding these risk factors is crucial for early detection and appropriate management of tethered spinal cord disease to prevent potential complications and improve outcomes.

Congenital spinal cord abnormalities increase the risk of developing tethered spinal cord disease.
History of spinal cord trauma or surgery can predispose individuals to tethered spinal cord.
Certain genetic conditions, such as spina bifida, are associated with a higher likelihood of tethered spinal cord.
Presence of a fatty mass or tumor near the spinal cord may contribute to tethered spinal cord development.
Individuals with a history of spinal infections are at an increased risk of developing tethered spinal cord disease.

Diagnosis of Tethered Spinal Cord Disease

A thorough physical examination may reveal symptoms such as back pain, leg weakness, or changes in bladder and bowel function. Imaging tests like MRI or CT scans help visualize the spinal cord and identify any abnormalities like spinal cord tethering. Neurological testing, including electromyography (EMG) and nerve conduction studies, can assess nerve function and identify any nerve damage. A comprehensive diagnostic approach is essential to confirm the presence of tethered spinal cord disease and guide appropriate treatment decisions.

Imaging tests like MRI and CT scans help diagnose tethered spinal cord disease by visualizing spinal cord abnormalities.
Electromyography (EMG) may be used to assess nerve function and detect abnormalities associated with tethered spinal cord.
A physical examination by a neurologist may reveal symptoms typical of tethered spinal cord, such as back pain or lower extremity weakness.
Neurological tests like sensory testing and reflex assessments can help identify signs of tethered spinal cord disease.
A thorough medical history review is crucial in diagnosing tethered spinal cord, including symptoms, past surgeries, and family history.

Treatment for Tethered Spinal Cord Disease

Treatment options for Tethered spinal cord disease aim to alleviate symptoms and prevent further neurological complications. Surgical intervention is often necessary to release the tethered spinal cord and restore proper spinal cord function. This procedure involves detethering the spinal cord to relieve tension and improve mobility. Post-surgery, physical therapy may be recommended to enhance strength, flexibility, and overall quality of life. Medications can also be used to manage pain and other associated symptoms. Regular monitoring and follow-up care are essential to track progress and address any recurrent issues. Overall, a multidisciplinary approach involving neurosurgeons, physical therapists, and other healthcare professionals is crucial for optimal management of Tethered spinal cord disease.
