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.
