DefinitionBy Mayo Clinic Staff
Diffuse idiopathic skeletal hyperostosis (DISH) is a bony hardening (calcification) of ligaments in areas where they attach to your spine.
Also known as Forestier's disease, diffuse idiopathic skeletal hyperostosis may cause no symptoms and require no treatment. The most common symptoms are mild to moderate pain and stiffness in your upper back. DISH can also affect your neck and lower back. Some people have DISH in other areas, such as shoulders, elbows, knees and heels.
A non-inflammatory condition, DISH can be progressive. As it worsens, it can cause serious complications.
