Thoracic Disc Proximal Extraforaminal Prolapse

A thoracic? disc prolapse occurs when the soft center (nucleus pulposus) of an intervertebral disc in the mid‐back pushes through a tear in its tough outer layer (annulus fibrosus) and migrates laterally outside the neural foramen, compressing the exiting nerve root before it enters the foramen (“proximal extraforaminal”) Desert Institute for Spine CareBarrow Neurological Institute. Although thoracic? disc herniations are rare—accounting for less than 1% of all spinal herniations—they can cause severe pain?: Back pain means pain in the spine, muscles, discs, joints, or nerves of the back. সহজ বাংলা: পিঠ/কোমরের ব্যথা।" data-rx-term="back pain" data-rx-definition="Back pain means pain in the spine, muscles, discs, joints, or nerves of the back. সহজ বাংলা: পিঠ/কোমরের ব্যথা।">back pain?, radicular symptoms (pain along a nerve), weakness?, numbness?, balance trouble, or coordination problems. সহজ বাংলা: স্পাইনাল কর্ডের সমস্যা।" data-rx-term="myelopathy" data-rx-definition="Myelopathy means spinal cord dysfunction, often causing weakness, numbness, balance trouble, or coordination problems. সহজ বাংলা: স্পাইনাল কর্ডের সমস্যা।">myelopathy?

Types

Morphological Types

1. Disc Protrusion: The disc nucleus bulges outward, but the outer annulus fibrosus remains intact, causing mild to moderate nerve irritation without free fragments Verywell HealthNCBI.

2. Disc Extrusion: A tear in the annulus allows the nucleus pulposus to break through while still remaining connected to the disc, often causing more pronounced nerve root compression Verywell HealthNCBI.

3. Disc Sequestration: A fragment of the nucleus pulposus completely separates from the disc and can migrate within the spinal canal or along nerve roots, potentially provoking acute?, severe pain? Verywell HealthNCBI.

Location-Based Types

Thoracic? disc herniations are further classified by where the disc material extends relative to the spinal canal:

1. Central: Into the center of the spinal canal, risking spinal cord compression.

2. Centrolateral (Paracentral): Just to one side of the canal, often affecting one side of the cord or nerve roots.

3. Foraminal: Within the neural exit foramen, impacting the nerve root as it leaves the spine.

4. Proximal Extraforaminal: Lateral to the foramen, compressing the nerve’s initial segment outside the spine.

5. Distal Extraforaminal: Further lateral beyond the costotransverse junction, affecting the nerve away from the vertebral column NCBINSPC Brain & Spine Surgery.
