Spontaneous Air Reduction of Vertebra Plana with Kummell's Disease During Vertebroplasty: Subsequent Experience with an Intentional Trial

摘要

Kummell's disease, known as the delayed posttraumatic osteonecrosis of the vertebral body, is characterized by a vertebral compression fracture with osteonecrosis. Necrotic changes cause air or fluid collection in the fractured vertebra, which shows a pathognomonic radiologic finding "intravertebral vacuum cleft" [1]. Vertebral augmentation procedures, such as vertebroplasty (VP) and kyphoplasty (KP), are well known to be effective in managing vertebral compression fractures [2].
