Abstract
The present invention provides devices, systems and methods for anchoring medical devices to hard tissues, such as bones or bony structures, particularly vertebrae. By anchoring these medical devices directly to the surrounding hard tissue, the devices are anchored closer to the source of treatment. This provides additional stability and reduces migration of the device at the treatment site. Also, by attaching to hard tissue rather than soft tissue, a stronger attachment is often able to be made.
