Abstract
The invention provides methods for treating spinal stenosis by pedicle distraction. The vertebral segment is cut so that the pedicles are separated from the main portion of the vertebral segment. After being cut, each pedicle is separated from the main portion and fixed at a distance from the main portion using screws. For example, two-component compression screws or stenosis screws may be used to fix the pedicles from the main portion. The screws may be inserted through bores drilled into the vertebral segment. The bores are preferably drilled prior to the cutting. As a result of fixing the cut portion at a distance from the main portion, there will be a gap between the main portion and the two pedicles, thereby enlarging the cross-section of the spinal column.
