Abstract
A spinal fixation device and method for the stabilization of the spine after surgical procedures such as those related to degenerative disc diseases are described. The device comprises a spacer, which is placed between adjacent vertebrae when installed and a locking mechanism attached to the spacer. The locking mechanism attaches the device to the spinous processes of adjacent vertebrae of the spine in a manner which is non-invasive with respect to the vertebrae to which it is attached.
