Diffuse Idiopathic Skeletal Hyperostosis (DISH): Symptoms & Signs

Medically Reviewed on 11/9/2020

Diffuse idiopathic skeletal hyperostosis (DISH) is a form of arthritis characterized by a particular type of calcium deposit along the sides of the vertebrae (backbones) of the spine. Unlike typical degenerative arthritis, DISH is commonly associated with inflammation (tendinitis) and calcification of tendons where they attach to bone. The condition is also known as h.

Signs and symptoms of DISH include

  • intermittent pains in the areas affected by the calcium deposits and
  • inflammation.

Stiffness and loss of range of motion in the spine are other associated symptoms. Bone spurs, such as heel spurs, are common in people with DISH as a result of the inflammation.

Cause of a diffuse idiopathic skeletal hyperostosis (DISH)

The cause of DISH is unknown.

Other diffuse idiopathic skeletal hyperostosis symptoms

  • Bone Spurs
