Thoracic Radiculopathy

What is Thoracic Radiculopathy?

Thoracic radiculopathy is irritation or compression of a thoracic nerve root in the mid back. The thoracic spine is the middle portion of the spine, located between the neck and lower back. Thoracic nerve roots travel from the spine around the ribs, chest wall, and upper abdomen.

When a thoracic nerve root is irritated, pain may wrap around the chest, ribs, side, or abdomen in a band-like pattern. Patients may describe the pain as burning, sharp, aching, stabbing, or electric-like. Thoracic radiculopathy is less common than cervical radiculopathy in the neck or lumbar radiculopathy in the lower back.

De Novo Brain & Spine evaluates adult patients with suspected or confirmed thoracic radiculopathy when symptoms suggest thoracic nerve compression, thoracic disc herniation, spinal stenosis, spinal instability, fracture, tumor, infection, deformity, or another structural spine condition that may require neurosurgical review.

Common Signs and Symptoms

Thoracic radiculopathy symptoms depend on which thoracic nerve root is affected and whether the nerve irritation is mild, moderate, or severe. Symptoms may feel like they are coming from the chest, ribs, abdomen, or mid back.

Common signs and symptoms may include:

• Mid back pain
• Pain that wraps around the ribs, chest wall, side, or upper abdomen
• Band-like burning, tingling, or numbness around the trunk
• Sharp, stabbing, aching, or electric-like pain
• Pain that worsens with twisting, bending, coughing, sneezing, deep breathing, or certain positions
• Numbness or pins-and-needles sensation along the ribs or trunk
• Muscle tightness or spasms in the mid back
• Pain between the shoulder blades
• Weakness, balance problems, or trouble walking if the spinal cord is affected
• Symptoms that may be mistaken for heart, lung, gastrointestinal, or abdominal conditions

Seek urgent medical evaluation for thoracic radiculopathy symptoms with progressive weakness, numbness, trouble walking, loss of coordination, bowel or bladder changes, fever, unexplained weight loss, history of cancer, severe pain after trauma, or rapidly worsening neurological symptoms. Seek emergency medical care or call 911 for chest pain, shortness of breath, fainting, sudden weakness, sudden speech difficulty, loss of consciousness, or symptoms that may suggest a heart, lung, stroke, or other emergency condition.

What Causes This Condition?

Thoracic radiculopathy occurs when a thoracic nerve root becomes irritated, inflamed, or compressed. Because thoracic pain can overlap with chest or abdominal symptoms, evaluation may also need to consider non-spine causes.

Possible causes and related conditions may include:

• Thoracic herniated disc, when disc material presses on or irritates a thoracic nerve root
• Thoracic degenerative disc disease
• Thoracic foraminal stenosis, which is narrowing where a nerve exits the spine
• Facet joint disease or arthritis-related spine changes
• Bone spurs, also called osteophytes
• Thoracic spinal stenosis
• Vertebral compression fracture
• Osteoporotic spinal fracture
• Traumatic spinal fracture
• Scoliosis or kyphosis, which may change spinal alignment and nerve root space
• Spinal instability in selected cases
• Shingles, also called herpes zoster, which can cause nerve pain around the chest wall
• Diabetes-related thoracic radiculopathy in selected patients
• Spinal tumor, infection, inflammatory disease, or cyst in less common cases
• Prior thoracic spine surgery or recurrent nerve compression in selected patients

These causes and risk factors do not mean every patient with mid back, rib, chest wall, or abdominal pain has thoracic radiculopathy. Treatment planning depends on symptoms, neurological examination, imaging findings, medical history, and overall health.

How Thoracic Disc Herniation Can Affect Nerves and the Spinal Cord

A thoracic disc herniation occurs when disc material in the mid back extends beyond its usual position. Depending on its location and size, it may affect nearby nerve roots, the spinal cord, or other structures within the spinal canal.

When a nerve root is involved, symptoms may be felt around the ribs, chest wall, side, or abdomen. If the spinal cord is affected, symptoms may involve the legs, balance, coordination, or walking.

Not every thoracic disc herniation causes symptoms, and imaging findings do not always explain a person’s pain by themselves. Clinical evaluation helps determine whether a disc finding is related to the symptoms being experienced.

How It Is Diagnosed?

Thoracic radiculopathy is diagnosed through medical history, physical examination, neurological examination, and imaging or nerve testing when appropriate. Because thoracic radiculopathy can mimic chest, lung, abdominal, or gastrointestinal conditions, the diagnostic process may also involve ruling out non-spine causes.

Common diagnostic steps may include:

• Medical history and symptom review to understand mid back pain, rib pain, chest wall pain, abdominal symptoms, numbness, tingling, weakness, triggers, injury history, and prior treatment
• Physical examination to evaluate posture, thoracic spine motion, muscle tenderness, rib movement, and painful motion
• Neurological examination to assess strength, sensation, reflexes, coordination, gait, balance, and signs of nerve root or spinal cord involvement
• Evaluation for non-spine causes when symptoms could involve the heart, lungs, abdomen, or other medical systems
• X-rays of the thoracic spine to evaluate alignment, arthritis, disc space narrowing, scoliosis, kyphosis, fracture, or degenerative change
• MRI of the thoracic spine to evaluate thoracic nerve compression, disc herniation, spinal stenosis, spinal cord compression, tumor, infection, fracture, or other soft-tissue findings
• CT scan of the thoracic spine when bone detail, fracture, deformity, or surgical planning requires further evaluation
• CT myelogram in selected cases when MRI is not possible or when additional detail around the spinal cord and nerve roots is needed
• Electromyography and nerve conduction studies, also called EMG/NCS, in selected cases when symptoms may overlap with another nerve condition
• Blood tests in selected cases when infection, inflammatory disease, cancer-related concern, or another medical condition is suspected
• Diagnostic injections in selected cases when a thoracic nerve root, facet joint, or other pain source needs further evaluation

The goal of diagnosis is to identify whether symptoms are caused by thoracic nerve root irritation, determine the cause of compression or inflammation, and decide whether conservative care, injections, or surgical evaluation may be appropriate.

Treatment Options

Thoracic radiculopathy treatment depends on the cause, severity, duration, neurological examination, imaging findings, prior treatment, activity limitations, and overall health. Many patients begin with non-surgical care when there is no progressive neurological deficit, spinal cord compression, fracture, infection, tumor, or other urgent concern.

Treatment options may include:

• Activity modification to reduce movements, twisting, lifting, or positions that worsen symptoms
• Physical therapy to improve posture, thoracic mobility, core strength, flexibility, shoulder mechanics, and spine stability
• Home exercise and stretching when recommended by a clinician or therapist
• Heat, ice, or other comfort measures for short-term symptom relief
• Anti-inflammatory medication, acetaminophen, muscle relaxants, or nerve pain medication when medically appropriate
• Treatment of posture, ergonomic, or activity-related contributors
• Thoracic epidural steroid injection in selected cases involving thoracic nerve root inflammation
• Selective thoracic nerve root block in selected cases when diagnostic or therapeutic nerve-targeted injection is appropriate
• Treatment of shingles-related nerve pain when herpes zoster or postherpetic neuralgia is the cause
• Treatment of fracture, tumor, infection, or inflammatory disease when one is identified
• Thoracic decompression in selected cases involving structural nerve compression or spinal cord compression
• Thoracic discectomy in selected cases involving thoracic disc herniation with significant nerve or spinal cord compression
• Spinal fusion or stabilization in selected cases involving instability, deformity, trauma, tumor, or certain fractures
• Rehabilitation and follow-up care to monitor pain, strength, sensation, walking, function, and neurological status

Surgery is not appropriate for every patient with thoracic radiculopathy. Neurosurgical treatment may be considered when symptoms are caused by structural nerve compression, spinal cord compression, progressive neurological symptoms, fracture, instability, tumor, infection, or persistent symptoms that do not improve with appropriate non-surgical care.
