The spine is made up of bones called vertebrae. These vertebrae are separated from one another by discs. Each vertebra also has a thick bony portion in the front called the vertebral body. This part supports most of our body weight. Osteoporosis is the most common disease in women above the age of 50. It affects one out of two people, and is characterized by a deterioration of bone quality caused by aging that can result in fragile areas more susceptible to breaking under impact.
Other diseases, such as cancer or malignant tumors, can also cause bone weakening.
