Abstract

A method for inserting a bone block into a patient's intervertebral space, comprising: supporting the bone block in an inserter; advancing the inserter into the intervertebral space; rotating the inserter, thereby separating adjacent vertebrae; separating the bone block and the inserter with a push rod; and removing the inserter from the intervertebral space.

Claims (15)

1. A method for inserting a plurality of bone blocks in a patient's intervertebral space, comprising:

supporting a first bone block in a first inserter;

advancing the first inserter into the intervertebral space;

rotating the first inserter, thereby positioning the first bone block between adjacent vertebrae;

removing the first inserter;

supporting a second bone block in a second inserter;

advancing the second inserter into the intervertebral space;

rotating the second inserter, thereby positioning the second bone block between adjacent vertebrae;

removing the second inserter.

2. The method of claim 1 , wherein each of said first and second bone blocks comprise opposite vertebral contact surfaces and opposite sides spanning between the opposite vertebral contact surfaces, and wherein the bone block tapers between longitudinally spaced apart ends to create a lordotic angle between adjacent vertebrae in the patient's intervertebral space.

3. The method of claim 1 , wherein each of said first and second bone blocks has lateral protrusions which extend longitudinally along the length of the bone block.

4. The method of claim 1 , wherein each of said first and second bone blocks has an angled front end.

5. The method of claim 1 , wherein each of said first and second inserters have two arms disposed on opposite sides of each of said first and second bone blocks, at least one arm extending substantially the entire length of the each of said first and second bone blocks.

6. The method of claim 1 , wherein each of said first and second inserters have two arms disposed on opposite sides of each of said first and second bone blocks, each arm having a longitudinally extending groove on an inner surface adjacent to the each of said first and second bone blocks.

7. The method of claim 1 , wherein each of said first and second inserters have two arms disposed on opposite sides of each of said first and second bone blocks, each arm having an outer convexly curved camming surface.
