tethered spinal cord syndrome

What is Tethered Spinal Cord Syndrome?

Tethered spinal cord syndrome (TSCS) is a disorder of the nervous system caused by tissue that attaches itself to the spinal cord and limits its movement [1]. This condition occurs when the lower end of the spinal cord becomes fixed or attached in place, which can cause various symptoms and complications.

Causes and Types

Two primary conditions are responsible for TSCS: myelomeningocele and lipomyelomeningocele [8]. Myelomeningocele is a congenital defect where the spinal cord and meninges protrude through an opening in the spine, while lipomyelomeningocele is a fatty tumor that attaches to the spinal cord.

Symptoms

The symptoms of TSCS can vary depending on the individual but often include:

• Back pain or shooting pain in the legs [3]
• Weakness, numbness, or problems with how leg muscles work [3]
• Tremors or muscle spasms
• Bladder and bowel dysfunction

These symptoms can develop slowly over time and may become severe in adults [9].

Key Points

• TSCS is a disorder of the nervous system caused by tissue attachment to the spinal cord.
• Two primary conditions cause TSCS: myelomeningocele and lipomyelomeningocele.
• Symptoms include back pain, weakness, numbness, tremors, and bladder/bowel dysfunction.

Common Signs and Symptoms of Tethered Spinal Cord Syndrome

Tethered spinal cord syndrome, also known as caudal regression syndrome or lipomyelomeningocele, is a rare condition where the spinal cord becomes attached to the spine, leading to various symptoms. Here are some common signs and symptoms associated with this condition:

• Back pain: Pain in the lower back, which can worsen with activity and improve with rest [1][2]
• Leg pain: Pain or discomfort in the legs, especially in the back of the legs [3][4]
• Leg numbness or tingling: Numbness or tingling sensations in the legs or feet [5][6]
• Weakness in the legs: Weakness or loss of strength in the legs or feet [7][8]
• Difficulty walking: Trouble with, or changes in, walking patterns due to muscle weakness or numbness [9]
• Lesions on the lower back: Hairy patches, dimples, or fatty tumors on the lower back [5]
• Discoloration of the skin: Discoloration of the skin in the lumbar region [9]

These symptoms can vary depending on age and individual factors. In older children and adults, symptoms may be more subtle and include back pain, leg pain, weakness in the legs, or fatigue.

Diagnosing Tethered Spinal Cord Syndrome

Tethered spinal cord syndrome (TSCS) can be diagnosed using various tests, which help identify the condition and its severity. Here are some common diagnostic tests used to diagnose TSCS:

• MRI: Magnetic Resonance Imaging is the most common test used to diagnose TSCS. It provides detailed views of the spinal cord, nerves, and surrounding tissues [1]. MRI imaging can show where the tethering is located, which helps doctors determine the best course of treatment [3].
• Clinical assessments: Clinical evaluations are also essential in diagnosing TSCS. Patients often present with symptoms such as pain, motor or sensory deficits, and bladder/bowel dysfunction [5].
• Ultrasound: An ultrasound test may be performed to confirm the diagnosis, especially in children suspected of having TSCS [6].

Diagnostic Accuracy

Studies have shown that MRI has moderate to high diagnostic sensitivity and specificity for diagnosing TSCS [2][4]. A small number of studies have reported varying results, but overall, MRI remains a reliable test for diagnosing this condition.

Other Tests

While not as common, other tests like CT scans and clinical assessments may also be used in conjunction with MRI to confirm the diagnosis. However, these tests are generally less accurate than MRI in diagnosing TSCS.

In conclusion, diagnosing tethered spinal cord syndrome requires a combination of clinical evaluations and imaging tests. MRI is the most reliable test for diagnosing this condition, providing detailed views of the spinal cord and surrounding tissues.

Medication Options for Tethered Spinal Cord Syndrome

While surgery is often the primary treatment for tethered spinal cord syndrome, medication can also play a role in managing symptoms and alleviating discomfort.

• NSAIDs: Nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen may be prescribed to help reduce pain and inflammation associated with the condition [1].
• Painkillers: Codeine or hydrocodone, which are types of painkillers, might also be used to manage chronic pain in patients with tethered spinal cord syndrome [2].

However, it's essential to note that medication alone may not be sufficient to treat the underlying condition. In many cases, surgical intervention is necessary to address the physical tethering of the spinal cord.

Differential Diagnosis of Tethered Spinal Cord Syndrome

Tethered spinal cord syndrome (TSCS) can be challenging to diagnose, and a comprehensive differential diagnosis is essential to rule out other conditions that may present with similar symptoms. Here are some key points to consider:

• Spina bifida: A congenital defect where the spine does not form properly, leading to an open or closed neural tube defect. [1]
• Diastematomyelia: A rare congenital anomaly where the spinal cord is split into two parts, often associated with TSCS. [9]
• Spinal stenosis: Narrowing of the spinal canal, which can cause compression of the spinal cord and lead to symptoms similar to TSCS. [1]
• Cauda equina syndrome: A condition where the nerves in the lower spine are compressed or damaged, leading to symptoms such as pain, weakness, and numbness. [2]
• Spinal tumors: Benign or malignant growths on the spinal cord that can cause compression and lead to symptoms similar to TSCS. [3]
• Dermatological conditions: Certain skin conditions, such as neurofibromatosis type 1 (NF1), can be associated with TSCS. [4]
• Musculoskeletal disorders: Conditions such as scoliosis or spondylolisthesis can cause compression of the spinal cord and lead to symptoms similar to TSCS. [5]

Key Diagnostic Features

When differentiating between these conditions, it's essential to consider the following diagnostic features:

• Imaging studies: MRI or CT scans are crucial for visualizing the spine and identifying any abnormalities that may be contributing to the patient's symptoms.
• Clinical presentation: A thorough medical history and physical examination can help identify the specific symptoms and signs associated with each condition.
• Laboratory tests: Blood tests, such as complete blood counts (CBCs) or electrolyte panels, may be necessary to rule out underlying metabolic disorders.
