Abstract

A serrated bone graft section for graft in a patient includes a body portion cut from elongate cortical bone, the body portion having a sidewall portion, the body portion having substantially planar end faces at opposite ends of said body portion, each of the end faces having a plurality of grooves cut therein so as to form serrations in each of the end faces.

Claims

1. A serrated bone graft section for graft in a patient, comprising a body portion cut from elongate cortical bone, the body portion having a sidewall portion, the body portion having substantially planar end faces at opposite ends of said body portion, each of the end faces having a plurality of grooves cut therein so as to form cross-cut serrations in each of the end faces, wherein a substantial portion of each end face planar surface area.

2. The section of claim 1, wherein said planar end faces are parallel with respect to each other.

3. The section of claim 2, wherein said plurality of grooves includes a first set of substantially parallel grooves in each end face.

4. The section of claim 3, further including a second set of substantially parallel grooves in each of the end faces which crosses said first set of substantially parallel grooves to form said cross-cut serrations.

5. The section of claim 4, wherein the first and second sets of substantially parallel grooves are substantially perpendicular to each other.

6. The section of claim 5, wherein the first and second sets of substantially parallel grooves each include at least about three grooves.

7. The section of claim 6, wherein said body portion has a length of from about 8 mm to about 80 mm, and wherein said body portion has a diameter of from about 10 mm to about 27 mm.

8. A serrated bone graft section for graft in a patient, comprising a body portion cut from elongate cortical bone, the body portion having a sidewall portion, the body portion having substantially planar end faces at opposite ends of said body portion, each of the end faces having a plurality of grooves cut therein so as to form cross-cut serrations in each of the end faces, wherein a substantial portion of each end face is planar surface area wherein said substantially planar end faces are not parallel, and are angled with respect to each other.

9. The section of claim 8, wherein said plurality of grooves includes a first set of substantially parallel grooves in each end face.

10. The section of claim 9, further including a second set of substantially parallel grooves in each of the end faces which crosses said first set of substantially parallel grooves to form said cross-cut serrations.

11. The section of claim 10, wherein the first and second sets of substantially parallel grooves are substantially perpendicular to each other.

12. The section of claim 11, wherein the first and second sets of substantially parallel grooves each include at least about three grooves.

13. The section of claim 12, having an anterior length dimension (T1) of from about 5 mm to about 17 mm, and a posterior length dimension (T2) of from about 8 mm to about 20 mm.

14. The section of claim 13, having a diameter of from about 15 mm to about 27 mm.
