Diffuse Idiopathic Skeletal Hyperostosis (DISH)

Diffuse Idiopathic Skeletal Hyperostosis (DISH) Facts

Diffuse idiopathic skeletal hyperostosis (DISH) is a condition that causes bone to form in abnormal places. DISH most commonly affects the mid back (thoracic spine) but may also affect the neck (cervical spine), low back (lumbar spine), hips, heels, and other areas. DISH is also known as Forestier's disease, spondylitis ossificans ligamentosa, spondylosis hyperostotica, and ankylosing hyperostosis of the spine. The exact cause of DISH is not known. DISH is more common in men than women and the elderly. DISH is uncommon before age 40. Decreased range of motion of the spine, especially in the mid back, is the most common sign of DISH. The diagnosis of DISH is made using X-rays. The treatment of DISH involves treating each bothersome symptom, if there are any.

Diffuse Idiopathic Skeletal Hyperostosis Causes

The exact cause of DISH is not known. A variety of factors are thought to contribute to its development, such as metabolic conditions. For example, DISH is more common in obese people and those with diabetes, as well as up to 20% of people with acromegaly (a rare condition caused by abnormal levels of growth hormone). It is more common in men than women and the elderly. DISH is uncommon before age 40.

DISH Overview

Diffuse idiopathic skeletal hyperostosis (DISH) is a disorder in which there is bone growth in the ligaments, particularly where they attach to the bones of the spine. You may have no symptoms, or you could have relatively minor spinal stiffness and pain. Over time your spine will stiffen and your vertebrae may fuse together.
