Abstract

An instrument for holding a bone plate may include a first arm, a second arm connected to and adjustable relative to the first arm, a first connection tip at the distal end of the first arm configured to connect to the first side wall of the bone plate, and a second connection tip at the distal end of the second arm configured to connect to the second side wall of the bone plate. A stabilizing member is connected to the first connection tip. The stabilizing member is distally spaced apart from the first connection tip to form an opening for receiving a portion of bone between the first connection tip and the stabilizing member.

First claim

The invention claimed is:

1. A method of expanding the spinal canal of a vertebra comprising:
cutting completely through the first lamina to create a space in the first lamina,
cutting partially through a second, contra-lateral lamina of the vertebra to create a partial cut in the second lamina,
connecting a first plate segment of a bone plate to a plate holding member of a plate holding instrument,
manipulating the plate holding instrument to position the first lamina in a space between a second plate segment of the bone plate and a stabilizing member of the plate holding instrument to thereby stabilize the first lamina,
pivoting the first lamina about the partial cut in the second lamina to increase the extent of the space in the first lamina,
connecting the second plate segment to the first lamina, and
connecting a third plate segment of the bone plate to a portion of the vertebra across the space from the second plate segment such that the first plate segment spans the increased space and the bone plate stabilizes the vertebra.

2. The method of claim 1 , wherein the first lamina is stabilized by the plate holding instrument during the pivoting of the first lamina.

3. The method of claim 1 , wherein pivoting of the first lamina occurs after connecting the second plate segment to the first lamina.

4. The method of claim 3 , wherein the first lamina is stabilized by the plate holding instrument during connecting of the second plate segment to the first lamina.

5. The method of claim 1 , further comprising adjusting the first plate segment relative to the plate holding member to change the space between the second plate segment of the bone plate and the stabilizing member to correspond to the thickness of the first lamina.

6. The method of claim 5 , further comprising adjusting the first plate segment in a first direction to increase the space between the second plate segment of the bone plate and the stabilizing member.

7. The method of claim 5 , further comprising adjusting the first plate segment in a second direction, to decrease the space between the second plate segment of the bone plate and the stabilizing member.
