APPARATUS AND METHODS FOR VERTEBRAL AUGMENTATION

摘要

The apparatus comprises elongated members (2200) which are inserted into vertebrae and secured to an arcuate fixation rod (2300) by clamps (2400) which when moved along the rod cause the elongated members and attached vertebrae to pivot. The method may further include passing through a cannula (2100) and into the a damaged vertebra a disruption tool for fracturing the damaged vertebral body. Once the cortical bone is broken or otherwise disrupted, the height of the damaged vertebral body may be restored, for example by removing the disruption tool and inserting through the cannula another tool, implant, device and/or material to restore the height of the vertebral body and to restore normal spinal curvature in the affected area. Grafting material or filler may be added with or without an implanted device to augment the damaged vertebral body.
