Fig. 6. Osteoporotic compression fracture with an intravertebral cleft (IVC) at the L1 level in a 83-year-old male. A : Computed tomography scan shows a gas filled IVC, indicative of Kummell's disease. B and C : Simple radiographs after bone cement-augmented percutaneous short segment screw fixation show restored vertebral height and improved kyphotic deformity. D and E : Simple radiographs taken at 12 months after surgery reveal a well-maintained kyphotic angle.
