Thoracic Disc Herniation

The backbone, or spine, is made up of 26 bones called vertebrae. The thoracic spine (mid-back region) consists of twelve bones (T1-T12 vertebrae). Vertebrae are separated from one another by soft discs filled with a jelly-like substance. These disks cushion the spinal column and put space between the vertebrae. The discs allow movement between the vertebrae.

As you age, the discs break down or degenerate. As they do, they lose their cushioning ability which can lead to pain if the back is stressed.

A herniated (slipped) disk occurs when all or part of a disc is displaced which may place pressure on nearby nerves or the spinal cord.

Symptoms of Thoracic Disc Herniation

Thoracic disc herniation is rare and can be asymptomatic; however, symptoms of thoracic disc herniation may include:

• Pain in the mid-back and/or torso - chest, abdomen - which may radiate to the groin
• Tingling and numbness that may travel around the rib cage from the back to the front of the chest or upper abdomen
• Weakness in arms or legs
• Bladder and bowel dysfunction

Risk Factors for Thoracic Disc Herniation

Risk factors may include:

• Trauma
• Metabolic abnormalities
• Genetic predisposition
• Vascular problems
• Infections
