Figures
- Fig 1.
A 75-year-old woman with compression fractures at T12 and L1, which were treated with vertebroplasty. A, Postoperative CT scan with sagittal re-formation shows intradiskal cement leakages at L1-L2 disk space (arrow). B, Postoperative axial CT shows cement leakage into the paravertebral vein at T12 on the left (arrow).
- Fig 2.
An 85-year-old woman with a compression fracture at L1, which was treated with kyphoplasty. A, Postoperative CT scan with sagittal re-formation shows no intradiskal cement leakage from the L1 vertebral body. B, Postoperative axial CT scan again shows no cement leakage from the L1 vertebral body.
