Learning more about DISH (Diffuse Idiopathic Skeletal Hyperostosis), a form of Arthritis

(Diffuse Idiopathic Skeletal Hyperostosis), also known as Forestier’s disease, is a non-inflammatory condition where tendons and ligaments around the spine and other joints harden or turn into bone (ossification). This creates flowing bone spurs—often described as looking like dripping candle wax—most commonly along the right side of the middle (thoracic) spine. [1, 2, 3, 4, 5]

Key Symptoms

• Stiffness and Pain: Morning stiffness and dull pain in the upper back, neck, or lower back. [1, 2, 3]
• Reduced Range of Motion: Decreased flexibility and difficulty turning the neck or bending the spine. [1, 2, 3]
• Swallowing Difficulties (Dysphagia): Large bone spurs in the neck (cervical spine) can press against the esophagus. [1, 2]
• Hoarseness or Sleep Apnea: Pressure on the vocal cords or airway from cervical bone spurs. [1, 2, 3]
• Peripheral Joint Issues: Aches, spurs, or stiffness in the shoulders, elbows, hips, knees, or heels. [1, 2]
• Nerve Compression or Fracture Risk: Numbness or weakness if nerves are pinched, plus a higher risk of severe spinal fractures from minor falls. [1, 2, 3]

Causes and Risk Factors

• Age and Sex: Most common in adults over age 50 and affects men twice as often as women. [1, 2]
• Metabolic Conditions: Strongly linked to type 2 diabetes, obesity, and metabolic syndrome. [1, 2, 3]
• Other Factors: High levels of vitamin A or retinoid use (such as isotretinoin), or genetic predisposition. [1, 2]

Diagnosis and Management

• Diagnosis: Confirmed via X-rays or CT scans showing flowing bone bridging at least four continuous vertebrae while keeping normal disc spaces and no major inflammation in the joints. Detailed information is outlined by the Cleveland Clinic and PubMed Central. [1, 2, 3, 4]
• Treatment: There is no cure to reverse existing bone spurs. Care focuses on managing pain and maintaining mobility through:
  • Over-the-counter pain relievers or prescription anti-inflammatory drugs (NSAIDs)
  • Physical therapy and low-impact exercise
  • Managing underlying conditions like blood sugar and weight
  • Surgery (such as removing bone spurs or spinal stabilization) in rare cases involving severe swallowing problems, airway restriction, or fractures. [1, 2, 3, 4, 5, 6]
