미만성 특발성 골격 과골증 환자에서 척추 유합술 후 발생한 후만 변형 - 증례 보고 -

초록

Study Design: Case report. Objectives: To report a case of progressive kyphotic deformity after spinal fusion in a patient with diffuse idiopathic skeletal hyperostosis (DISH). 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. 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.
