강직성 척추염 환자에서 발생한 일반 방사선 사진으로 확인되지 않은 흉추의 파열골절 1례

초록

Patients with ankylosing spondylitis (AS) are at high risk for spinal fracture even after a minor injury. Most spinal fractures with ankylosing spondylitis occur in the cervical spine, whereas spinal fractures in thoracic or lumbar spine are rare. These fractures are often difficult to detect on standard radiographs, because the normal anatomical landmarks are lacking and the abnormal spinal stiffness precludes optimal exposure of the spine. We report on a case of a 12th thoracic spine fracture in ankylosing spondylitis with bamboo spine after a minor injury. In this case, anteroposterior and lateral radiographs of the thoracolumbar spine showed a bamboo spine typical for ankylosing spondylitis with no evidence of fracture. However, computed tomography showed a 12th thoracic fracture with burst. Therefore, this fracture, in a patient with AS involved all three spinal columns, was considered unstable.
