Thoracic spondylosis materializes as a condition marked by degenerative changes occurring within the thoracic spine. Over time, these changes encompass the development of bone spurs (osteophytes) and the breakdown of spinal discs. Such degeneration leads to pain, stiffness, and a diminished range of motion.

As spinal discs undergo deterioration, their capacity to cushion and support the vertebrae diminishes. Consequently, friction between the vertebrae escalates, instigating the formation of bone spurs as the body endeavors to stabilize the affected area. The presence of bone spurs intensifies pain and stiffness, with the potential to compress nearby nerves, resulting in radiating discomfort.

Individuals grappling with thoracic spondylosis often endure a gradual onset of symptoms. Dull aches or stiffness in the middle or upper back become recurrent, intensified by activities necessitating twisting or bending of the spine. A decrease in the range of motion within the affected area is frequently observed.
