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.
Signs and symptoms might include:Stiffness. Stiffness may be most noticeable in the morning.Pain. You may feel pain in your back or in other affected areas, such as your shoulder, elbow, knee or heel.Loss of range of motion. You may notice this most when stretching side to side.Difficulty swallowing or a hoarse voice. You may experience these if you have DISH in your neck.
The treatment of DISH involves treating each bothersome symptom. If no bothersome symptoms are present, then no treatment is necessary. The treatment of DISH should be individualized for the patient and their specific signs and symptoms. Physical activity and physical therapy are usually beneficial for patients suffering from spinal stiffness. For example, stretching and gentle exercise generally help with stiffness.
