THORACIC SPINAL STENOSIS

Questions and Answers

Understanding the Differences Between Thoracic, Cervical, and Lumbar Spinal Stenosis

Spinal stenosis is a condition that involves narrowing of the spinal canal, but its impact varies significantly depending on whether it occurs in the thoracic, cervical, or lumbar regions of the spine. Here’s how thoracic spinal stenosis stands apart from its cervical and lumbar counterparts:

Thoracic Spinal Stenosis

• Location and Rarity: The thoracic spine is located in the middle section of the spine and connects to the ribs. Thoracic spinal stenosis is less common because the thoracic spine is more stable and less prone to degeneration compared to its cervical and lumbar counterparts.
• Symptoms: This form can lead to complications involving the heart and lungs due to its anatomical location. Symptoms may include numbness, muscle weakness, or even problems with balance, often presenting differently than in other types of spinal stenosis.
• Diagnosis and Challenges: Because it’s rare, diagnosis can be more challenging. It often requires thorough imaging tests like MRI or CT scans to identify the precise area of narrowing.

Cervical Spinal Stenosis

• Location: This occurs in the neck region. Since the cervical spine supports the head and facilitates a wide range of head movements, stenosis here can potentially compress the spinal cord.
• Symptoms: It may cause neck pain, radiating pain or numbness in the arms and hands, and in severe cases, issues with walking or coordination due to spinal cord compression.
• Urgency of Treatment: Often, it’s considered more urgent than other types because of the risk to the spinal cord leading to serious neurological deficits.

Lumbar Spinal Stenosis

• Location: Found in the lower back, it is the most common type of spinal stenosis due to the high degree of mobility and weight-bearing responsibilities of this region.
• Symptoms: Typically involves leg pain, numbness, or cramping that worsens with standing or walking and improves with sitting or bending forward.
• Treatment Approaches: Physical therapy, lifestyle changes, and sometimes surgery are considered to manage symptoms effectively.

Conclusion

Each type of spinal stenosis brings its unique set of challenges based on its location. Understanding these distinctions helps in both diagnosing and formulating an effective treatment plan tailored to the specific needs of the patient. Whether you’re experiencing symptoms or seeking to learn more, being informed is the first step towards managing your spinal health effectively.

Thoracic Stenosis Causes:

Older people are more likely to acquire thoracic spinal stenosis since it can come from normal aging. This condition, known as spinal stenosis, occurs gradually, slowly reducing the spinal cord’s space and/or room for the nerves in the area. However, older adults are not the only ones at risk. Other elements, though, are equally crucial.

Key Risk Factors

• Thickened Tissues and Bone Spurs: These conditions can narrow the spinal canal, increasing the likelihood of stenosis.
• Degenerative Disc Disease: Over time, discs can wear down, compromising the space within the spinal canal.
• Herniated and Bulging Discs: These can press against the nerves, exacerbating stenosis symptoms.
• Arthritic Spurs: These bony growths can contribute to spinal narrowing.

Because their spinal canal has been affected, those with thicker tissues, bone spurs, degenerative disc disease, herniated discs, bulging discs, and arthritic spurs are more prone to get thoracic spinal stenosis. Osteoarthritis also causes this illness, which affects elderly individuals more frequently. Osteoarthritis develops when the cartilage that ordinarily cushions the ends of our bones wears away. This allows the bones to scrape against one another.

Understanding these risk factors can help in the early identification and management of thoracic spinal stenosis, potentially improving quality of life for those affected.

In addition, the following factors may contribute to spinal stenosis:

• Degenerative Changes: The aging process can lead to degeneration of the spine, including the intervertebral discs and facet joints, contributing to stenosis.
• Herniated Discs: Disc herniation in the thoracic region can result in compression of the spinal cord.
• Osteoarthritis: Degeneration of the facet joints due to osteoarthritis can contribute to the narrowing of the spinal canal.
• Traumatic Injuries: Injuries to the spine, such as fractures or dislocations, can cause structural changes that lead to stenosis.
• Spondylolisthesis: This condition involves the displacement of one or more vertebrae.
• Bone spurs: They could enlarge into the spinal canal, pressing the nerves.
• Enlarged facet joints: The cartilage inside the facet joint may swell up due to degenerative changes in the joints between the vertebrae.
• Spinal canal ligament irritation; This inflammation may result in restriction.

Understanding the causes sets the stage for recognizing the diverse symptoms associated with Thoracic Stenosis.

Symptoms:

• Back Pain: Persistent, aching pain in the mid-back appears as a common symptom of thoracic stenosis.
• Numbness or Tingling: Compression of nerves can lead to sensations of numbness or tingling in the chest or abdomen.
• Weakness: Weakness in the legs or difficulty with balance may occur due to spinal cord compression.
• Bowel or Bladder Dysfunction: Severe cases of thoracic stenosis can lead to bowel or bladder dysfunction, requiring urgent medical attention.
• Gait Disturbances: Changes in walking patterns may manifest due to the impact on the spinal cord.

In addition to these symptoms, it’s crucial to differentiate between pain that can be managed non-surgically and pain that may require surgical consideration:

• Non-Surgical Pain: Typically affects the central or para-spinal soft tissue and does not radiate into the arms, chest, or legs. This type of pain usually responds well to non-surgical symptomatic treatment.
• Radiating Pain: Pain that extends from the spine into the extremities or chest wall is a sign of potential structural pinching of the nerves in the spine. This condition may necessitate a surgical opinion, especially if there’s no improvement within days to weeks with non-surgical treatment.

By understanding these distinctions, you can better identify when spinal pain might be a signal for more serious intervention. If you experience radiating pain that persists despite non-surgical treatments, it’s advisable to seek a surgical consultation promptly.

Diagnosis:

Diagnosing thoracic stenosis involves a combination of patient history, physical examination, and diagnostic imaging.

• Medical History and Physical Examination: The doctor will inquire about the patient’s symptoms, their onset, and conduct a thorough physical examination.  The doctor will then assess neurological function, reflexes, and signs of spinal cord compression.
• Imaging Studies: MRI and CT scans are valuable tools for visualizing the spinal canal and identifying the extent of stenosis.

To further confirm the diagnosis and pinpoint the exact source of the problem, additional imaging tests are often employed:

• X-rays: These are used to determine the presence of bone spurs and assess spinal instability.
• MRI: This imaging test helps visualize any nerves that are being compressed due to thoracic spinal stenosis.
• EMG: If neurological damage is suspected, an EMG may be requested to evaluate irritation or nerve damage.

By utilizing a combination of these imaging studies, healthcare providers can achieve a comprehensive understanding of the spinal condition.  This will lead to a more accurate diagnosis and effective treatment plan.
Once diagnosed, doctors can manage thoracic stenosis through various treatment modalities, including both non-surgical and surgical options.

Non-Surgical Treatment:

Physical Therapy: Physical therapy focuses on improving posture, strengthening core muscles, and maintaining flexibility to alleviate symptoms. Sessions of physical therapy exercises specifically target the muscles in the thoracic region. By strengthening these muscles, physical therapy can contribute to lessening the pressure in the area, which is crucial for treating thoracic spinal stenosis. This targeted approach not only helps in reducing pain but also enhances overall spinal stability.

Medications: Doctors will prescribe pain medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs) or muscle relaxants, to manage pain and discomfort.

• NSAIDs: Non-steroidal anti-inflammatory drugs like acetaminophen, naproxen, and ibuprofen can help reduce inflammation, which often leads to pain.
• Prescription Medications: For more severe cases, prescription medications can help block nerve pain. Additionally, cortisone or steroid injections can provide immediate pain relief.

By offering a range of options, from over-the-counter NSAIDs to stronger prescription medications, doctors tailor pain management strategies to the severity of your condition.

Corticosteroid Injections: In some cases, doctors will administer corticosteroid injections to reduce inflammation around compressed nerves.

Surgical Treatment:

In cases where non-surgical interventions fail to provide sufficient relief, doctors will consider surgical options. Surgical treatment may be necessary when spinal pain radiates into the arms, legs, or around the rib cage.  Typically, non-surgical low back, cervical, and thoracic pain affects the central or para-spinal soft tissue without radiating into the extremities.

However, pain that travels from the spine into the arms, chest, or legs implies structural pinching of the nerves in the spine. If this situation fails to improve within days to weeks with non-surgical symptomatic treatment, a surgical opinion may be required to address the issue effectively. This approach ensures that patients receive the appropriate level of care for their specific condition, whether through continued non-surgical methods or surgical intervention.
When conservative treatments have failed to reduce symptoms, or if there is a risk of nerve damage or myelopathy, a surgical approach may be necessary to treat thoracic spinal stenosis.

Surgical Procedures

Several surgical procedures can be employed to address thoracic spinal stenosis:

• Laminectomy/Laminotomy: This procedure involves the removal or partial removal of the lamina to create more space for the nerves, thereby relieving pressure on the spinal canal.
• Foraminotomy / Foraminectomy: By expanding the foramen, this surgery increases the space for nerve roots to exit the spinal canal, helping to release pinched nerves.
• Discectomy: Involves the removal of a bulging disc or the part of the disc pressing on nerves, providing pressure release and pain relief.

These surgical treatments offer targeted relief and can significantly improve the quality of life for individuals suffering from thoracic spinal stenosis.

Minimally invasive laminectomy

The most popular surgical treatment for treating spinal stenosis is minimally invasive laminectomy. This procedure is a non-fusion operation that widens the spinal canal and relieves pressure on the nerves. A minimally invasive laminectomy involves making a small incision in the back.  Surgeons then move muscles laterally to access the affected area of the spine. The lamina, a component of the vertebral arch, is then pierced to relieve compression. With no sutures to remove and little muscle damage, we carry out this surgery endoscopically through a less than an inch-long incision. Following surgery, patients just require a BAND-AID. Patients should anticipate going home the same day because more than 95 percent of minimally invasive laminectomy treatments are done as outpatient procedures.

Spinal fusion

To connect the vertebrae with a bone graft or other materials, we frequently conduct thoracic spinal fusion surgeries. The spine will become stronger and more stable as a result. When deciding whether a patient can undergo a minimally invasive operation or whether they require an open fusion procedure, we consider a number of variables. Surgeons may conduct some Spinal Fusions via a minimally invasive procedure with a one inch incision.

Minimally invasive foraminotomy

In order to prevent compression of the nerves in the spinal canal, we can enlarge that area using special equipment. A minor incision less than an inch long is used during minimally invasive foraminotomy.  This procedure will remove a fragment of bone and soft tissue.

Benefits of Surgical Treatment:

Relief from Compression Symptoms: One of the primary benefits of surgery is the potential for significant relief from symptoms associated with spinal cord compression.

Prevention of Neurological Decline: Surgery can prevent further deterioration of neurological function, preserving the patient’s ability to move and perform daily activities.

Enhanced Quality of Life: By addressing the structural changes associated with thoracic stenosis, surgery can contribute to an enhanced overall quality of life.

Recovery Period:

The recovery period following surgical treatment for thoracic stenosis varies based on the specific procedure performed and individual patient factors. Patients may undergo physical therapy to regain strength and flexibility, with a gradual return to normal activities. The recovery timeline becomes influenced by the extent of decompression or fusion performed.

Post-Surgery Instructions: 

Your surgeon will provide specific instructions following surgery, which usually include prescribing pain medication. In some cases, the surgeon may suggest wearing a spinal brace for weeks to months, depending on your specific post-surgical needs.

Resuming Daily Activities:

Guidance from your surgeon will help determine when you can resume normal activities such as returning to work, driving, and exercising. It’s essential to follow these guidelines closely to ensure a smooth recovery.

Rehabilitation and Physical Therapy:

Some patients may benefit from supervised rehabilitation or physical therapy after surgery. This type of treatment often requires a referral and can significantly aid in regaining strength and mobility.

Managing Discomfort and Pain: 

While it’s expected to experience some discomfort as you gradually return to normal activities, pain can signal that you need to slow down. The general expectation is a trend of gradual improvement over the first three or more months following surgery. Your surgeon will provide prognostic information to help you recognize any adverse post-operative trends that may necessitate an unplanned re-evaluation. These adverse signs can include fever, chills, wound drainage, new weakness, or changes in sensory or pain symptoms.

Individualized Treatment: 

It’s important to understand that there are usually no absolutes regarding the medical or surgical treatment of spinal conditions. Every patient is unique, and the best course of action may vary. This is why choosing a physician you feel comfortable with is critical. Whether a non-surgeon or surgeon, the best doctors are those you can trust to support you, even if the treatment outcome isn’t ideal. By following these guidelines and maintaining open communication with your healthcare provider, you can navigate your recovery period more effectively.
