摘要
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 The pedicle lengthening implant is originally made, or can be modified to, connect to the longitudinal member.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.
