The exact cause is unknown, but researchers believe it may be linked to:
- Metabolic Factors:
- Insulin resistance, obesity, or abnormal calcium metabolism.
- Genetic Predisposition:
- Family history may play a role.
- Mechanical Stress:
- Long-term stress on ligaments and tendons may contribute to excessive bone growth.
How Is DISH Diagnosed?
- Medical History and Physical Exam:
- Stiffness and pain patterns, along with risk factors, are evaluated.
- Imaging Tests:
- X-rays are the most common diagnostic tool, revealing characteristic flowing bony growths along the sides of the vertebrae.
- CT or MRI may be used for more detailed views, especially if nerves or soft tissues are affected.
- Blood Tests:
- Typically normal, as there is no inflammation, but tests may rule out other conditions like arthritis.
