What is the prognosis for individuals with diffuse idiopathic skeletal hyperostosis (DISH)?

People with diffuse idiopathic skeletal hyperostosis are at risk of certain complications, such as:[1]
  • Disability. Loss of range of motion in the affected joint can make it difficult to use that joint. For instance, diffuse idiopathic skeletal hyperostosis in the shoulder can make it difficult and painful to use the arm.
  • Difficulty swallowing. Bone spurs associated with diffuse idiopathic skeletal hyperostosis in the neck (cervical spine) can put pressure on the esophagus, making it difficult to swallow. The pressure from bone spurs can also cause a hoarse voice or difficulty breathing during sleep (sleep apnea). In rare circumstances this can become serious and may require surgery to remove the bone spurs.
  • Paralysis. Diffuse idiopathic skeletal hyperostosis that affects the ligament running up the outside of the spine (posterior longitudinal ligament) can put pressure on the spinal cord. Spinal cord compression may result in a loss of feeling and paralysis.
