Cho, Choi, Jung, and Park: Local Bone versus Autogenous Iliac Bone Graft for Posterolateral Lumbar Fusion in the Same Patient

Abstract

Study Design

A prospective study

Objectives

To determine the usefulness of local bone obtained from laminectomy and decortication as graft bone instead of autogenous iliac bone in posterolateral lumbar spinal fusion.

Materials and Methods

Thirty- one patients underwent posterolateral lumbar spinal fusion with pedicle screw instrumentation. Local bone was inserted in the right side of intertransverse space and autogenous iliac bone was in the left side. We compared fusion rate in the radiographs at postoperative 6 week, 3 month, 6 month and 1 year.

Results

Radiographic fusion grading of local bone was 20 cases of grade 1, 8 cases of grade 2, 2 cases of grade 3 and 1 case of grade 4. Fusion grading of autogenous iliac bone was 24 cases of grade 1, 4 cases of grade 2 and 3 cases of grade 3. Bone fusion was complete after 9.1 months in local bone and 7.2 months in autogenous iliac bone. No significant differences was found between the two groups.

Conclusion

The local bone in posterolateral lumbar fusion is appropriate for satisfactory fusion instead of autogenous iliac bone if the amount of local bone is sufficient and decortication of the fusion bed is proper.

A 48 year-old female underwent posterolateral lumbar fusion with pedicle screw instrumentation. Local bone was inserted in the right intertransverse space and autogenous iliac bone was in the left side. The radiogrphs were taken at postoperative 6 week, 3 month (A), 6 month and 1 year (B). The local bone was incoperated more rapidly than autogenous iliac 2 bone, but no significant differences was found between two groups.
