What is it ?
As in the case of cervical or lumbar herniations, thoracic disc herniation is due to natural aging of the spine. Many studies on mono-zygotic (real) twins have shown that disc degeneration is mostly genetically programmed. Statistically, the thoracic disc herniation is less frequent than the lumbar or cervical hernia. And as in these two anatomical regions, many radiologically visible herniated discs are asymptomatic.
