Thoracic Transverse Nerve Root Compression at the T3–T4

Thoracic transverse nerve root compression at the T3–T4 level is a form of thoracic radiculopathy in which the nerve root exiting the spinal canal between the third and fourth thoracic vertebrae becomes pinched or irritated. This can occur when intervertebral discs bulge or herniate, bony spurs narrow the neural foramen, or surrounding ligaments thicken. Because the thoracic spinal canal is relatively narrow and rigid compared to the cervical and lumbar regions, even small structural changes can impinge the nerve root, leading to localized pain, numbness, or tingling that may radiate around the chest or back in a band-like pattern. Over time, chronic compression can cause muscle weakness in the trunk and contribute to postural imbalance. Diagnosis typically involves a combination of detailed history, physical examination (including dermatomal sensory testing), electrodiagnostic studies, and high-resolution imaging such as MRI or CT myelography physio-pedia.com.

Thoracic transverse nerve root compression at T3–T4 happens when the nerve as it leaves the spinal cord at the third and fourth thoracic vertebral level gets pressed or squeezed. This pressure irritates the nerve, causing pain, numbness, or weakness along its path around the chest wall and trunk.

Types

1. Degenerative Compression
   When spinal discs or facet joints shrink or grow abnormally with age, they can narrow the nerve opening and press on the T3–T4 nerve root.

2. Traumatic Compression
   A sudden injury—like a fall or car crash—can fracture or dislocate a vertebra at T3–T4, pinching the nerve root.

3. Neoplastic Compression
   Tumors growing inside or near the spinal canal at T3–T4 can invade or push against the nerve root.

4. Infectious Compression
   Infections such as spinal epidural abscess or tuberculosis can swell tissues and pus near T3–T4, squeezing the nerve.

5. Iatrogenic Compression
   Medical treatments like spine surgery, injections, or radiation around the T3–T4 area can unintentionally injure or scar the nerve root.

Causes

1. Degenerative Disc Herniation
   The outer layer of the T3–T4 disc may tear, letting inner gel press onto the nerve root.

2. Facet Joint Hypertrophy
   Overgrown facet joints at T3–T4 can narrow the foramen where the nerve exits.

3. Ligamentum Flavum Thickening
   The yellow ligament can thicken with age, encroaching on the nerve pathway at T3–T4.

4. Spondylolisthesis
   One vertebra slips forward over another, misaligning the nerve canal at T3–T4.

5. Osteophyte Formation
   Bone spurs around T3–T4 from arthritis can grow into the neural foramen and pinch the nerve.

6. Vertebral Fracture
   A crack in T3 or T4 from trauma or osteoporosis can collapse the vertebra and trap the nerve.

7. Spinal Tumors
   Benign or cancerous growths inside the spinal canal near T3–T4 can press the nerve root.

8. Epidural Abscess
   A collection of pus between bone and dura mater can compress T3–T4 nerve roots.

9. Synovial Cysts
   Fluid-filled sacs from facet joints near T3–T4 can bulge into the nerve opening.

10. Rib Fracture Displacement
    A broken rib near the T3–T4 level can shift inward and press on the nerve.

11. Spinal Stenosis
    General narrowing of the spinal canal around T3–T4 reduces space for the nerve roots.

12. Epidural Lipomatosis
    Excess fat in the epidural space around T3–T4 can suffocate the nerve root.

13. Inflammatory Arthritis
    Conditions like rheumatoid arthritis can swell joints and tissues at T3–T4, compressing the nerve.

14. Hemorrhage
    Bleeding into the epidural space near T3–T4 can form a clot that presses on the nerve.

15. Vascular Malformation
    Abnormal blood vessels at T3–T4 can enlarge and crimp the nerve opening.

16. Congenital Spinal Canal Narrowing
    Some people are born with a tight canal at T3–T4, making compression more likely.

17. Iatrogenic Scar Tissue
    Scar formation after surgery near T3–T4 can entrap or tug on the nerve root.

18. Disc Calcification
    Hardening of the T3–T4 disc from calcium deposits can reduce disc height and squeeze the nerve.

19. Tuberculous Spondylitis
    Spinal tuberculosis destroys vertebral bone at T3–T4, leading to collapse and nerve compression.

20. Metastatic Disease
    Cancer spread from another site to T3–T4 vertebrae can invade bone and press on the nerve root.
