Summary
Diffuse idiopathic skeletal hyperostosis (DISH) can lead to spinal fractures and pseudoarthrosis, mimicking infections. Radiographic findings include disc space destruction and vertebral sclerosis.
Area of Science:
- Orthopedics
- Radiology
- Rheumatology
Background:
- Diffuse idiopathic skeletal hyperostosis (DISH) is a common ossifying diathesis affecting the vertebral skeleton.
- Spinal ankylosis in DISH predisposes the spine to stress and fracture.
- Fracture in ankylosed segments can lead to pseudoarthrosis due to continued motion.
