Most of the patients develop osteoporosis too. As a result, the spine loses its flexibility and durability and highly unstable fractures may occur at the lower cervical or lower thoracic spine, even after minor trauma.

The treatment of the fractures is usually surgical. The surgical approach is either posterior or a combination of anterior and posterior approaches and instrumentation at least two vertebra above and below the fracture level.
