T7–T8 Transverse Nerve Root Compression

Thoracic transverse nerve root compression at the T7–T8 level occurs when the nerve exiting the spinal canal between the seventh and eighth thoracic vertebrae is squeezed or irritated. This compression can happen inside the spinal canal (central) or where the nerve passes through the bony opening (foramen), leading to characteristic pain, sensory changes, and muscle weakness along the chest wall or abdomen. Because the T7–T8 nerve root supplies sensation and motor control to the chest’s midsection, patients often describe “band‐like” discomfort around the ribs or subtle weakness of the trunk muscles.

Thoracic transverse nerve root compression at T7–T8—often termed thoracic radiculopathy—occurs when the T7 or T8 spinal nerve roots are pinched as they exit the intervertebral foramen. This compression can stem from intervertebral disc herniation, osteophyte formation, ligamentous hypertrophy, or trauma, leading to inflammation, nerve ischemia, and demyelination of the affected root. Patients typically experience sharp, burning, or electric shock–like pain radiating around the chest or abdomen in a band‐like distribution corresponding to the T7–T8 dermatomes, sometimes accompanied by sensory changes or mild motor weakness in the abdominal wall muscles hopkinsmedicine.orgncbi.nlm.nih.gov.

Types of T7–T8 Transverse Nerve Root Compression

1. Intraforaminal Compression
   The nerve is pinched inside the intervertebral foramen (bony tunnel). Disc bulges or facet joint overgrowth often narrow this space, gently squeezing the nerve root as it leaves the spinal canal.

2. Extraforaminal Compression
   Here, pressure occurs just outside the foramen, usually from a herniated disc fragment or a bony spur pressing on the nerve after it exits. Symptoms are similar to intraforaminal but may spare certain sensory fibers.

3. Subarticular (Lateral Recess) Compression
   The nerve is compressed beneath the facet joint inside the spinal canal’s lateral recess. Typically caused by thickened ligaments or facet capsule swelling, it leads to localized back pain and segmental sensory loss.

4. Central Canal Narrowing
   Though more common in the lumbar spine, central thoracic stenosis at T7–T8 can compress multiple nerve roots or the spinal cord itself, producing a mix of motor and sensory signs below the level of compression.

5. Acute vs. Chronic Classification

   • Acute compression appears suddenly (e.g., trauma) and often causes sharp, severe pain.

   • Chronic compression develops over months (e.g., degenerative changes) and typically causes duller, persistent discomfort.

Causes of T7–T8 Nerve Root Compression

1. Degenerative Disc Disease
   Over time, spinal discs lose water and height, causing bulging that can press on the T7–T8 nerve root. This wear-and-tear process is the most common non-traumatic cause in older adults.

2. Thoracic Disc Herniation
   A rupture of the disc’s inner gel pushes material into the foramen, directly pinching the nerve. Although less frequent in the thoracic spine, herniations at T7–T8 can cause mid-back pain and radiating chest discomfort.

3. Facet Joint Osteoarthritis
   Arthritic changes enlarge the facet joints, narrowing the nerve’s exit pathway. Patients often report localized back stiffness that worsens with twisting or extension.

4. Spondylolisthesis
   When one vertebra slips forward over another, it can crush the exiting nerve root. Even a small shift at T7–T8 alters the foramen’s shape enough to create compression.

5. Spinal Stenosis
   A general narrowing of the spinal canal from ligament thickening or bone overgrowth can impinge the T7–T8 nerve root centrally or laterally. Symptoms usually build gradually.

6. Thoracic Spine Fracture
   Traumatic breaks can displace bone fragments into the canal or foramen, acutely compressing the nerve. High‐energy injuries like falls or car crashes are common culprits.

7. Spinal Tumors
   Both primary (originating in the spine) and metastatic (spread from another site) tumors can grow into the foramen or canal, pressing on T7–T8. Unexplained night pain or weight loss often raises suspicion.

8. Infectious Discitis or Osteomyelitis
   Bacterial infection inflames the disc space or vertebral body, leading to swelling and abscess formation that compress the nerve. Fever, elevated inflammatory markers, and localized tenderness support this diagnosis.

9. Rheumatoid Arthritis
   Autoimmune inflammation can erode facet joints and ligaments, producing bone spurs and ligament thickening that narrow the exit for the T7–T8 nerve. Systemic joint pain and high rheumatoid factor help identify this cause.

10. Calcified Ligamentum Flavum
    Degenerative calcification of the ligament that lines the back of the spinal canal stiffens and bulges inward, squeezing the nerve roots. This tends to occur in older patients with chronic back stress.

11. Schmorl’s Nodes
    Upward or downward disc herniations into adjacent vertebral bodies can alter load distribution, indirectly causing adjacent facet overgrowth and foraminal narrowing at T7–T8.

12. Thoracic Osteophytes (Bone Spurs)
    Bony projections from vertebral bodies or facets can encroach on the foramen. These spurs form over years of mechanical stress and arthritis.

13. Iatrogenic Postoperative Scarring
    Scar tissue after thoracic spine surgery may tether the nerve root, causing compression-like symptoms even without a new bone or disc lesion.

14. Intervertebral Cyst (Synovial or Ganglion)
    Fluid-filled sacs arising from facet joints can bulge into the foramen, gently pressing the nerve. These cysts often present with intermittent pain linked to joint activity.

15. Ligamentous Hypertrophy
    Thickening of supportive spinal ligaments (e.g., posterior longitudinal ligament) reduces canal size. Inflammatory or degenerative processes can drive this overgrowth.

16. Diabetic Neuropathy with Secondary Mechanical Compression
    Long-standing diabetes may cause nerve swelling; when combined with mild foraminal narrowing, the swollen nerve can be pinched at T7–T8.

17. Vitamin B12 Deficiency–Related Myelopathy
    Low B12 leads to spinal cord and nerve root vulnerability; even small degenerative changes at T7–T8 may then compress the weakened nerve more easily.

18. Tumoral Calcinosis
    Calcium deposits around spinal joints can form mass-like lesions that press on the T7–T8 nerve. This rare metabolic disorder often presents with elevated calcium levels on blood tests.

19. Ankylosing Spondylitis
    A form of inflammatory arthritis that fuses vertebrae and thickens ligaments, leading to rigid segments and potential foraminal narrowing at T7–T8. Look for HLA-B27 positivity and back stiffness.

20. Spinal Vascular Malformations
    Abnormal blood vessels (e.g., hemangiomas) within the vertebral body or epidural space can expand or bleed, indirectly compressing adjacent nerve roots. MRI with contrast typically reveals these lesions.

Symptoms of T7–T8 Nerve Root Compression

1. Mid‐Back Pain
   A deep, aching pain localized around the T7–T8 vertebrae. It often worsens with movement or prolonged sitting.

2. Radicular Chest Discomfort
   A band-like burning or stabbing sensation wrapping around the chest at the level of the seventh rib. This “rib belt” pattern follows the T7 dermatome.

3. Numbness or Tingling
   Patients may feel pins and needles or a loss of sensation in the mid-thoracic region or around their torso.

4. Muscle Weakness of the Trunk
   Weakness in the abdominal or intercostal muscles can lead to poor posture or a feeling of heaviness when bending or twisting.

5. Reduced Deep Tendon Reflexes
   The abdominal reflex (stroking the skin around the belly button) may be diminished on the affected side.

6. Gait Unsteadiness
   In severe or central compression, balance can be affected, causing unsteady walking or a wide‐based gait.

7. Pain with Cough or Sneeze
   Increased intra-abdominal pressure transiently worsens nerve irritation, leading to sharp spikes of pain during coughing or sneezing.

8. Postural Pain
   Pain that worsens when arching the back (extension) or twisting, as these movements further narrow the foramen.

9. Night Pain
   Discomfort that disrupts sleep, often due to increased disc hydration and height when lying flat.

10. Intercostal Muscle Twitching
    Visible or palpable muscle spasms along the ribs, resulting from irritated motor fibers.

11. Heat or Cold Intolerance
    Altered sensory fibers may cause the patient to feel too hot or too cold over the affected dermatome.

12. Allodynia
    Light touch that normally does not cause pain (like clothing pressing on skin) triggers discomfort on the T7–T8 segment.

13. Hyperalgesia
    A normally painful stimulus (like mild pressure) feels excessively painful in the compressed dermatome.

14. Muscle Atrophy
    Chronic compression can shrink intercostal or abdominal muscles, leading to a visible indentation on one side of the torso.

15. Autonomic Changes
    Though rare, sweating or flushing changes over the T7–T8 region may occur if nearby sympathetic fibers are affected.

16. Dysesthesia
    An unpleasant, abnormal sensation—often described as burning or electric shock—along the nerve distribution.

17. Reduced Thoracic Spine Mobility
    Stiffness and decreased range of motion when trying to bend or rotate the upper back.

18. Sensory Level on the Torso
    A clear horizontal line on the skin where sensation shifts from normal above to altered below T7–T8.

3. Range of Motion Testing
   Ask the patient to flex, extend, and rotate the thoracic spine; limited or painful motion suggests mechanical compromise.

4. Dermatomal Sensory Testing
   Light touch, pinprick, and temperature assessment over the T7 dermatome map sensory deficits.

5. Muscle Strength Grading
   Evaluate intercostal and abdominal muscle strength (e.g., trunk flexion against resistance) to detect weakness.

6. Deep Tendon Reflexes
   Check the upper abdominal reflex; reduced response may point to T7–T8 root involvement.

7. Gait and Balance Assessment
   Observe the patient walking and standing; ataxia or wide-based gait can appear in severe cases.
