Percutaneous Pedicle Screw Fixation with Bone Cement Augmentation Under Epidural Anesthesia for Treatment of Kummell Disease in Extremely Old Age

摘要

BACKGROUND: In cases of Kummell disease without neurologic deficit, petrcutaneous vertebroplasty or kyphoplasty has achieved short-term favorable outcomes. In the long term, recollapse of the augmented vertebral body and aggravation of kyphosis at the index level is often reported. Owing to medical comorbidities, elderly patients are often unsuited for extensive open spine surgery under general anesthesia.
