Prolapsed / Bulged Thoracic Disc

Prolapsed Disc Diagram

The disc is made from a jelly-like centre (nucleus pulposus) surrounded by a hard outer ring (annulus fibrosis). The jelly-like center can push against the outer ring. This may initially cause a bulging of the outer ring of the disc, called a bulging disc. However if there is enough force or if the outer annulus is very worn or damaged, the nucleus may squeeze all the way through. This is called a prolapsed or herniated disc. It often occurs with lifting, pulling, bending, or twisting movements.

Patients with this condition may experience a sudden onset of back pain during the causative activity, however, it is also common for patients to experience pain and stiffness after the provocative activity, particularly the next morning.

Symptoms are typically felt in the back and may be located centrally, on one side or on both sides of the spine.

If the prolapsed disk bulges out toward the spinal canal, it can put pressure on the sensitive spinal nerves. This can cause pain that radiates around the rib cage, pins and needles, numbness, shooting pains, and can cause muscle weakness.

Treatment for a Prolapsed / Bulged Thoracic Disc
Physiotherapy treatment for patients with this condition is vital to hasten the healing process, ensure an optimal outcome and decrease the likelihood of injury recurrence. Treatment may comprise:
