The present invention creates two pedicle cuts (osteotomy) in the vertebrae, separates each vertebral cut by inserting an implant into the cut, enlarges the spinal canal, and removes the separated vertebral cuts. The fixation of each expands the spinal canal, allowing the vertebra to heal with the spinal canal expanded. The implant includes two stents, two washers, two screws, and a cable. One stent is pushed into each pedicle cut of the vertebra. One screw is inserted into one washer and one stent and screwed into the front of the vertebra for each pedicle cut of the vertebra. A cable is attached to the washer at each end and tied around and through the posterior part of the vertebra, securing the posterior part of the vertebra to the anterior part of the vertebra, stabilizing the enlarged spinal canal, To allow the vertebra to heal in the expanded state. |
