Appl. No.:

12/624946

International Classification:

A61B 17/00

US Classification:

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.

Abstract:

Spinal canal expansion through pedicle lengthening in combination with spinal column stabilization, to treat spinal stenosis, spondylolisthesis, kyphosis, scoliosis or a major spinal rotational deformity, with or without a spinal fusion. A device or implant that includes a pedicle lengthening implant to decompress (expand) the spinal canal, and a bridge to connect two or more pedicle lengthening implants and/or pedicle screws or bone anchors to achieve simultaneous spinal stabilization across one or more vertebral segments. The bridge across the vertebral segments can include a longitudinal member, such as a plate or rod. The pedicle lengthening implant is originally made, or can be modified to, connect to the longitudinal member. Spinal deformity can be manipulated, through operation of one or more pedicle lengthening implants in respective vertebral segments, to improve a relative relationship between the respective vertebra segments, the longitudinal member then fixating the vertebral segments into a multi-level spinal construct.
