SUMMARY OF LITERATURE REVIEW: DISH is characterized by spinal and peripheral enthesopathy, and is a completely different disease from ankylosing spondylitis (AS). Though DISH can be associated with thoracic kyphosis, no reports have described a progressive thoracolumbar kyphotic deformity after spinal fusion surgery in a DISH patient. MATERIALS AND METHODS: A 47-year-old male presented with pain in the thoracolumbar region. After excluding the possibility of AS and confirming the diagnosis of DISH, we performed spinal fusion for the treatment of a T11-T12 flexion-distraction injury. The kyphotic deformity was found to be aggravated after the first operation, and we then performed corrective osteotomy and additional spinal fusion. Results: The kyphotic deformity of the patient was corrected after the second operation. RESULTS: The kyphotic deformity of the patient was corrected after the second operation. CONCLUSIONS: In DISH patients in whom AS must be excluded in the differential diagnosis, a kyphotic deformity can become aggravated despite spinal fusion surgery, so regular and continuous follow-up is required.
