Thoracic Disc Herniation Surgery

Surgery for thoracic disc herniation involves removing a disc fragment that is compressing the spinal cord in the thoracic region. Because the spinal cord occupies most of the thoracic canal, these herniations require careful surgical approaches — often from the side or front rather than directly from the back.

Surgery is considered when a thoracic disc herniation causes myelopathy (spinal cord dysfunction), significant radiculopathy, or progressive neurological symptoms. Incidental thoracic disc herniations found on imaging are common and usually do not require treatment.

Thoracic disc herniations are uncommon as a surgical problem but can be serious when they compress the spinal cord. The key challenge is approach selection — a standard posterior laminectomy is generally not safe here because retracting the thoracic spinal cord carries significant risk. Lateral or anterolateral approaches provide safer access. This is a case where the surgeon's experience with the specific anatomy matters a great deal.

• Spinal cord injury
• Intercostal neuralgia
• Dural tear and CSF leak
• Pneumothorax
• Infection
• Incomplete decompression

Hospital stay is usually two to four days. Patients may have temporary chest wall discomfort from the approach. Recovery to full activity takes six to twelve weeks, with neurological improvement sometimes continuing for months.
