Abstract
A method for correcting spinal stenosis involves cannulating a passage in a vertebra, and placing a distal portion of an implant therein. Then, a circumferential vertebral cut is performed from within the passage, using a proximal end of the distal portion of the implant to align the vertebral cut. Then, a proximal portion of the implant is placed into the passage, positioned against the distal portion at the vertebral cut. Operation of the distal and the proximal portions of the implant relative to one another widens the vertebral cut and expands the spinal canal. The proximal portion can then be secured to the distal portion to stabilize the vertebral cut, allowing vertebral healing with the spinal canal expanded. Flanges may exist that radially extend outward from the implant and into the vertebral cut, or into the passage walls, to assist vertebral cut widening and stabilization.
