Complications
- if a patient with DISH sustains spine fractures are at increased risk of instability due to ligamentous calcification and increased deforming forces secondary to vertebral ankylosis
- there is evidence that surgical treatment of cervical fractures in elderly patients with DISH correlates with a 15% rate of mortality compared to 67% after conservative treatment, highlighting the importance of prompt diagnosis, evaluation, and treatment after trauma in patients with DISH (1)
- heterotopic ossification is a frequent complication following total hip arthroplasty in patients with DISH (30 t0 56%) - compares to 10 to 22% in patients without DISH
